Future Watch: Guerrero Jr. nabs top spot after hot start Blue Jays prospect Vladimir Guerrero Jr. collected at least one hit in all but one of his first six games at Double-A New Hampshire.

These rankings are put together based on information gathered from various prospect sources, conversations with evaluators inside and outside the Jays organization, as well as personal opinion.

I am not a scout, so any notes gathered on pitcher mechanics or notable swing changes throughout the season are coming from an outside source.

While the first list on April 4 outlined who the top 20 prospects in the organization are, the purpose of this weekly ranking from this point forward is to highlight how players have done over the past seven days (from Wednesday through Tuesday) and shuffle them up accordingly.

If you see Vladimir Guerrero Jr. as the seventh name on the list one week, it doesn’t mean he’s suddenly the seventh-best prospect in the system. It just means six other prospects from this top 20 performed better over a seven-day period.

We hope you enjoy this weekly snapshot that will run through the end of August when minor league seasons come to a close.

1. 3B Vladimir Guerrero Jr.

2018 affiliate: Double-A New Hampshire

Age: 19 (3/16/1999)

Height: 6-foot-1 | Weight: 200

Top 100 prospect rankings: Baseball America (3), MLB Pipeline (3), Keith Law ESPN (2), Baseball Prospectus (4), FanGraphs (3)

Projected MLB ETA: 2019

Season stats: .304/.379/.696 with 2 HR, 8 RBI, 0 SB in 30 plate appearances at Double-A

Past week: .304/.379/.696 with 2 HR, 8 RBI, 0 SB in 30 plate appearances at Double-A

In his first six games at Double-A, Vladdy Jr. collected at least one hit in all but one, and in the game he didn’t get a base hit, he walked twice. He hit a couple of tape-measure home runs, but he got more attention for the sacrifice bunt he laid down during the new extra-inning format that had everyone asking why in the world would a manager have one of the best bats in the minors bunting. Fisher Cats manager John Schneider told John Lott of The Athletic it was Vladdy’s doing, showing his selflessness. It’s worth noting repeatedly that he’s the youngest player in the Eastern League by more than a year and a half.

2. SS Bo Bichette

2018 affiliate: Double-A New Hampshire

Age: 20 (03/05/1998)

Height: 6-foot-0 | Weight: 200

Top 100 prospect rankings: Baseball America (8), MLB Pipeline (13), Keith Law ESPN (17), Baseball Prospectus (19), FanGraphs (9)

Projected MLB ETA: 2019

Season stats: .393/.433/.464 with 0 HR, 3 RBI, 3 SB in 30 plate appearances at Double-A

Past week: .393/.433/.464 with 0 HR, 3 RBI, 3 SB in 30 plate appearances at Double-A

Hitting second ahead of Guerrero Jr. in a stacked Fisher Cats lineup, the second-youngest player in the Eastern League also had a terrific debut, banging out 11 hits in 28 at-bats. After an 0-for-4 on opening day, Bichette decided to get back to his multi-hit ways, and heads into Wednesday night’s game in Trenton riding a streak of five multi-hit efforts.

3. RHP Sean Reid-Foley

2018 affiliate: Double-A New Hampshire

Age: 22 (08/30/1995)

Height: 6-foot-3 | Weight: 220

Projected MLB ETA: 2020

Season stats: 1-0, 0.00 ERA, 0.67 WHIP, 6 IP, 1 hits, 3 BB, 7 K at Double-A

Past week: 1-0, 0.00 ERA, 0.67 WHIP, 6 IP, 1 hits, 3 BB, 7 K at Double-A

Even though he’s repeating Double-A this season, Reid-Foley got off to an excellent start, as he tries to rebuild his prospect status after last year’s 5.09 ERA. The Jays are hoping a number of arms that regressed last season reverse that course in 2018.

4. 2B/SS Lourdes Gurriel Jr.

2018 affiliate: Double-A New Hampshire

Age: 24 (10/19/1993)

Height: 6-foot-2 | Weight: 185

Projected MLB ETA: 2019

Season stats: .375/.414/.583 with 0 HR, 7 RBI, 1 SB in 29 plate appearances at Double-A

Past week: .375/.414/.583 with 0 HR, 7 RBI, 1 SB in 29 plate appearances at Double-A

After a year of adjusting both on and off the field following his defection from Cuba, this is the type of week the Jays expect more of this season. His only asset defensively will be versatility – he’s focusing on the middle infield spots, but the Jays have seen him play outfield while scouting him and believe he’ll be fine out there if needed – but there’s no doubting his natural ability to hit.

5. INF Cavan Biggio

2018 affiliate: Double-A New Hampshire

Age: 23 (04/11/1995)

Height: 6-foot-1 | Weight: 203

Projected MLB ETA: 2020

Season stats: .353/.389/.765 with 1 HR, 5 RBI, 0 SB in 18 plate appearances at Double-A

Past week: .353/.389/.765 with 1 HR, 5 RBI, 0 SB in 18 plate appearances at Double-A

Overshadowed by all of the other fancy last names in the Fisher Cats’ lineup, lefty-swinging Biggio is an interesting prospect in his own right. The 2016 fifth-rounder out of Notre Dame isn’t tooled up like Guerrero and Bichette, but neither was his Hall-of-Fame father. Similar to Gurriel, versatility is the Jays’ goal with Biggio, and he’s already appeared at first base and second base. Third base time is also expected this season.

6. OF/1B Ryan Noda

2018 affiliate: Low-A Lansing

Age: 22 (03/30/1996)

Height: 6-foot-3 | Weight: 217

Projected MLB ETA: 2020

Season stats: .333/.565/.533 with 0 HR, 4 RBI, 2 SB in 23 plate appearances at Low-A

Past week: .333/.565/.533 with 0 HR, 4 RBI, 2 SB in 23 plate appearances at Low-A

Noda arrived on the scene as a 15th-round pick out of the University of Cincinnati last summer and still hasn’t stopped hitting. After slashing .364/.507/.575 in 66 games for rookie-level Bluefield, Noda picked up right where he left off, walking seven times and striking out only twice in 23 trips to the plate in his first week in Lansing.

7. C Danny Jansen

2018 affiliate: Triple-A Buffalo

Age: 22 (04/15/1995)

Height: 6-foot-2 | Weight: 225

Top 100 prospect rankings: FanGraphs (71)

Projected MLB ETA: 2018

Season stats: .714/.778/1.429 with 1 HR, 1 RBI, 0 SB in 9 plate appearances at Triple-A

Past week: .714/.778/1.429 with 1 HR, 1 RBI, 0 SB in 9 plate appearances at Triple-A

The Bisons’ entire season-opening series in Rochester against the Red Wings was postponed due to snow, but that didn’t seem to affect Jansen, who went 4-for-4 with a home run in their first game of the season Monday in Pawtucket.

8. LHP Ryan Borucki

2018 affiliate: Triple-A Buffalo

Age: 24 (03/31/1994)

Height: 6-foot-4 | Weight: 175

Projected MLB ETA: 2018

Season stats: 0-1, 3.60 ERA, 1.60 WHIP, 5 IP, 6 hits, 2 BB, 3 K at Triple-A

Past week: 0-1, 3.60 ERA, 1.60 WHIP, 5 IP, 6 hits, 2 BB, 3 K at Triple-A

After making one start at the highest level of the minors to finish out a highly successful 2017 season, Borucki made his second Triple-A start Tuesday, allowing two runs over five innings against Pawtucket, the Red Sox’ top affiliate. The lefty threw 78 pitches, with 48 of them going for strikes.

9. RHP T.J. Zeuch

2018 affiliate: High-A Dunedin

Age: 22 (08/01/1995)

Height: 6-foot-7 | Weight: 225

Projected MLB ETA: 2020

Season stats: 1-0, 6.00 ERA, 1.00 WHIP, 6 IP, 4 hits, 2 BB, 5 K at High-A

Past week: 1-0, 6.00 ERA, 1.00 WHIP, 6 IP, 4 hits, 2 BB, 5 K at High-A

Zeuch worked six innings on opening day for Dunedin, and it was a pair of home runs ruining an otherwise solid outing. The 6-foot-7 right-hander threw 50 of 76 pitches for strikes and recorded 11 ground-ball outs. The Jays considered sending him to Double-A to start the year, so he might not be in High-A long if he gets results.

10. 2B Samad Taylor

2018 affiliate: Low-A Lansing

Age: 19 (07/11/1998)

Height: 5-foot-10 | Weight: 160

Projected MLB ETA: 2022

Season stats: .214/.421/.214 with 0 HR, 0 RBI, 1 SB in 19 plate appearances at Low-A

Past week: .214/.421/.214 with 0 HR, 0 RBI, 1 SB in 19 plate appearances at Low-A

Taylor is a potential breakout name to watch in the Jays’ system this summer, but it was a quiet debut for the lithe second baseman in the state of Michigan. One of the underrated aspects of Taylor is his ability to take a walk. He drew five of them in four games.

11. SS Logan Warmoth

2018 affiliate: High-A Dunedin

Age: 22 (09/06/1995)

Height: 6-foot-0 | Weight: 190

Projected MLB ETA: 2020

Season stats: .200/.333/.200 with 0 HR, 0 RBI, 1 SB in 18 plate appearances at High-A

Past week: .200/.333/.200 with 0 HR, 0 RBI, 1 SB in 18 plate appearances at High-A

The North Carolina Tar Heels product skipped over Low-A and landed in Dunedin to start his first full minor-league season. It was a quiet debut with just three hits in 15 at-bats, but he walked twice and only struck out once.

12. C Riley Adams

2018 affiliate: High-A Dunedin

Age: 21 (06/26/1996)

Height: 6-foot-4 | Weight: 225

Projected MLB ETA: 2021

Season stats: .125/.125/.375 with 1 HR, 3 RBI, 0 SB in 16 plate appearances at High-A

Past week: .125/.125/.375 with 1 HR, 3 RBI, 0 SB in 16 plate appearances at High-A

The defence is coming along and there’s lots of power in the bat, but Adams will have to curb the swing and miss as he climbs the ladder. In his first week in Dunedin, the third-round pick from a year ago struck out eight times in 16 trips to the plate.

13. C Reese McGuire

2018 affiliate: Triple-A Buffalo

Age: 23 (03/02/1995)

Height: 5-foot-11 | Weight: 215

Projected MLB ETA: 2018

Season stats: .000/.111/.000 with 0 HR, 0 RBI, 0 SB in 9 plate appearances at Triple-A

Past week: .000/.111/.000 with 0 HR, 0 RBI, 0 SB in 9 plate appearances at Triple-A

One of the challenges facing Bisons manager Bobby Meacham this season is divvying up the at-bats between McGuire, Jansen and the glut of outfielders he’s expected to have on hand. There’s only so many DH at-bats to go around. His glove will get him to the majors eventually, but it will be interesting to monitor the bat this season.

14. 1B Rowdy Tellez

2018 affiliate: Triple-A Buffalo

Age: 23 (03/16/1995)

Height: 6-foot-4 | Weight: 220

Projected MLB ETA: 2019

Season stats: .143/.333/.143 with 0 HR, 0 RBI, 0 SB in 9 plate appearances at Triple-A

Past week: .143/.333/.143 with 0 HR, 0 RBI, 0 SB in 9 plate appearances at Triple-A

Tellez was added to the 40-man roster this off-season, but 2018 is a crucial year for the big first baseman. He’s lost his grip on the title of first baseman of the future, but the Jays still believe in the bat. He’ll have to show more power than the .333 slugging percentage he put up last season.

15. C/1B Max Pentecost

2018 affiliate: Double-A New Hampshire

Age: 25 (03/10/1993)

Height: 6-foot-2 | Weight: 191

Projected MLB ETA: 2019

Season stats: .091/.154/.182 with 0 HR, 1 RBI, 0 SB in 13 plate appearances at Double-A

Past week: .091/.154/.182 with 0 HR, 1 RBI, 0 SB in 13 plate appearances at Double-A

Pentecost was behind the plate for all three games he appeared in during the first week of the season, showing that the Jays truly are committed to letting him sink or swim as a catcher this season. If his shoulder holds up, the Jays won’t give up on their 2014 first-round pick, even if he’s already 25.

16. OF Anthony Alford

2018 affiliate: Triple-A Buffalo

Age: 23 (07/20/1994)

Height: 6-foot-1 | Weight: 215

Top 100 prospect rankings: Baseball America (60), MLB Pipeline (47), Keith Law ESPN (44), Baseball Prospectus (58), FanGraphs (36)

Projected MLB ETA: Made MLB debut May 19, 2017

Season stats: .333/.500/.333 with 0 HR, 0 RBI, 0 SB in 4 plate appearances at High-A

Past week: .333/.500/.333 with 0 HR, 0 RBI, 0 SB in 4 plate appearances at High-A

Sidelined since mid-March with a Grade 2 strain of his right hamstring, Alford started his rehab assignment Monday in Dunedin, singling and getting hit by a pitch in four trips to the plate. Once he’s deemed ready, he’ll report to Triple-A Buffalo and, hopefully, string together a couple months of health and production.

17. RHP Nate Pearson

2018 affiliate: High-A Dunedin

Age: 21 (08/20/1996)

Height: 6-foot-6 | Weight: 245

Top 100 prospect rankings: Baseball America (91), Keith Law ESPN (100), FanGraphs (76)

Projected MLB ETA: 2020

Season stats: N/A

Past week: N/A

The start to Pearson’s first full minor-league campaign has been delayed by a minor back issue that isn’t believed to be serious. Pearson was scheduled to start last Friday for Dunedin, but the Jays say they’re just being cautious with their prized pitching prospect and he won’t need a DL stint.

18. RHP Eric Pardinho

2018 affiliate: Extended spring training

Age: 17 (01/05/2001)

Height: 5-foot-10 | Weight: 155

Projected MLB ETA: 2024

Season stats: N/A\

Past week: N/A

Pardinho will marinate in extended spring training as a 17-year-old until further notice. The right-hander already sits at No. 7 on MLB Pipeline’s list of top 30 Blue Jays prospects.

19. SS Richard Urena

2018 affiliate: Triple-A Buffalo

Age: 22 (02/26/1996)

Height: 6-foot-0 | Weight: 185

Projected MLB ETA: Made MLB debut Sept. 1, 2017

Season stats: N/A

Past week: N/A

Urena is currently in extended spring training, working his way back from an undisclosed injury. He’ll be back in Buffalo when he’s ready to go.

20. LHP Thomas Pannone

2018 affiliate: Triple-A Buffalo

Age: 23 (04/28/1994)

Height: 6-foot-0 | Weight: 195

Projected MLB ETA: 2019

Season stats: N/A

Past week: N/A

Handed an 80-game suspension by Major League Baseball last month for testing positive for Dehydrochlormethyltestosterone (DHCMT), Pannone isn’t eligible to return until June 30.
