Down in the Midwest League (Class A), scouts have been flocking to Cedar Rapids' games to no doubt catch a glimpse of Byron Buxton and Jose Berrios, who are among the Twins' top prospects. To their credit, Buxton and Berrios haven't disappointed. Buxton -- who was the No. 2 overall pick in the 2012 draft and the consensus No. 2 prospect in Minnesota's system behind Miguel Sano -- is destroying pitching (.349/.597/1.049) in the Midwest League. Berrios -- who ranks up there with Alex Meyer, Kyle Gibson and Trevor May among the team's top pitching prospects -- hasn't lost in his first four starts (3-0) and is striking out 11.2 batters per nine innings. But there is another name starting to grab the attention of scouts, team executives and long-term Fantasy keeper owners -- Adam Brett Walker II. It sounds more like a name that belongs at an upscale country club than in a baseball lineup, but there's no mistaking Walker can hit. Walker's slash line (.309/.655/1.010) is equally impressive as Buxton's, and he was taken 95 picks after Buxton in the 2012 MLB draft. Walker leads the Midwest League with 44 RBI and hit his third grand slam of the season Tuesday. Baseball execs and scouts have been enamored with Walker's power potential since his college days at Jacksonville, but he slipped into the third round for multiple reasons -- most notably a high strikeout rate, a susceptibility to breaking pitches and having an average arm for an outfielder. While Walker is slugging .555 and has belted 24 home runs in his first 93 games, he's still striking out a lot -- averaging 1.2 strikeouts per game in his career -- and scouts feel he's destined to end up as a first baseman. But there's little denying this kid can rake if he makes contact. When talking about Walker's ceiling, Giancarlo Stanton comparisons often arise in scouting reports. A quick look at Stanton's minor-league numbers compare favorably to what Walker has done early in his career, including Stanton averaging 1.14 strikeouts per game. While no one, not even this writer, is ready to deem Walker the second coming of Stanton, his blistering start has warranted attention. At this pace, it might not be long before Walker is talked about in the same breath as Sano and Buxton. Now, let's move onto five other players in the minors grabbing headlines … Yordano Ventura, SP, Royals

Affiliate: Double-A Northwest Arkansas

2013 stats:3-0, 1.57 ERA, 1.02 WHIP, 47 strikeouts, 14 walks, one home run allowed in seven starts (34 1/3 innings)

Despite coming into spring training having made just six starts above Class A, Ventura was in the mix to make the starting rotation and remained in the thick of it until the end of camp. Though, the decision to start Ventura in the minors hasn't been a bad move for either party. The Royals are winning without Ventura's presence and the Dominican right-hander is building confidence dominating batters in the hitter-friendly Texas League. Ventura is striking out a career-high 12.3 batters per nine innings and allowing a career-low 5.5 hits per nine innings. Although Wade Davis and Luis Mendoza have ERAs north of 5.50, it's difficult to envision the Royals making a brash move to promote Ventura, who isn't even on the 40-man roster. Ventura is more likely to receive a promotion to Triple-A Omaha before landing in Kansas City. Eddie Butler, SP, Rockies

Affiliate: Class A Asheville

2013 stats: 4-1, 1.49 ERA, 0.85 WHIP, 45 strikeouts, 22 walks, two home runs allowed in eight starts (48 1/3 innings)

Although the Rockies lost Mark Ellis to NL West rival Los Angeles in free agency a few years ago, Colorado used its compensatory pick in the 2012 draft on Butler, who has the potential to be a frontline starter for years to come. It's a tradeoff that could have long-lasting implications. Since turning pro, Butler has gone 11-2 with a 1.86 ERA and 0.97 WHIP through 21 outings (20 starts). He commands a fastball that can touch the high 90s, his breaking pitches (curveball and slider) are overmatching minor-league hitters and the right-hander is working on developing a changeup. Given his college pedigree, Butler has the ability to move quickly through the Rockies' system and could be an impact arm in a few years. Addison Russell, SS, Athletics

Affiliate: Class A Stockton

2013 stats: .171/.302/.343/.644, two triples, three home runs, three stolen bases, five doubles, 11 RBI, 15 runs, 20 walks, 30 strikeouts in 27 games

Russell entered 2013 with hefty expectations following a stellar pro debut in 2012. The Athletics invited their consensus top prospect to spring training less than a year after being drafted in the first round, giving the appearance Russell had the makeup to sprint through the minor leagues despite being a high-school draftee. Sadly, Russell has struggled to start the season in the hitter-friendly California League. All Russell has to do is make contact and the baseball should have no problems traveling great distances. Although, let's not be too quick to write off Russell because of a slow start. He spent time on the disabled list in April because of a back injury and he still might be trying to find his rhythm. Although, if he's dealing with any lingering issues, it might not be such a bad thing. At least we would have a reason for his struggles. It's better than the talent evaluators missing on Russell or knowing Russell's struggles stem from him buckling under the pressure of being an elite prospect. Rubby De La Rosa, SP, Red Sox

Affiliate: Triple-A Pawtucket

2013 stats: 0-0, 4.35 ERA, 1.21 WHIP, 26 strikeouts, 10 walks, three home runs allowed in seven starts (20 2/3 innings)

De La Rosa was considered a top 100 prospect by Baseball America in 2011 before blowing out his arm and needing Tommy John surgery. He has had a slow road back, but he's finally ramping up the intensity at Pawtucket and returning to the form he had before reconstructive elbow surgery. Although he's still on a strict pitch count, De La Rosa has tossed four straight scoreless outings, spanning 14 innings. He's also had a 19-to-4 strikeout-to-walk ratio in that span. The Red Sox were over the moon when they landed Allen Webster and De La Rosa in a trade with the Dodgers last season, and their patience with De La Rosa could pay major dividends down the road. In fact, once De La Rosa gets his pitch count up, he might even have a spot in the Boston rotation later this summer. Rob Refsnyder, 2B, Yankees

Affiliate: Class A Tampa

2013 stats (two levels of Class A): .377/.476/.507/.983, one triple, one home run, 13 doubles, 13 stolen bases, 22 RBI, 22 walks, 23 strikeouts, 25 runs in 35 games

The 2012 fifth-round pick needed only 13 games this season before he was promoted from low Class A Charleston to high Class A Tampa. What's been most impressive is that Refsnyder has a higher batting average (.381) in more games (22) for Tampa than he did (.370) in fewer games for Charleston. Refsnyder was a key cog on Arizona's College World Series-winning team from 2012, picking up Most Outstanding Player honors along the way. Refsnyder was lauded for having great plate discipline and the ability to hit to all fields. Although he was an outfielder in college, the Yankees have transitioned Refsnyder to second base because they are unsure if his power will translate to the major-league level. It's been a rough go at second base for Refsnyder, who has committed 13 errors in 32 games this season, but the Yankees are committed to him as an infielder. Though, it won't be his defense that eventually sends him to the majors. It will be his bat -- making him an ideal candidate to put on your radar in long-term keeper leagues.
