A flurry of deals at the July 31 non-waiver trade deadline have roiled the MLB prospect waters and left the minors with no consensus No. 1 prospect. Three candidates for the top spot in our rankings (Yoan Moncada, Rafael Devers, and Amed Rosario) received big league promotions over the past few weeks, leaving the Yankees Gleyber Torres as the winner by default. But even if there isn't a clear No. 1 right now, there are still plenty of potential September call-ups who are worth watching for on fantasy baseball waiver wires, especially if you're in a Dynasty/Keeper league.

Torres is currently sidelined after Tommy John surgery on his left (non-throwing) elbow but he’s expected to make a full recovery and be ready to play again sometime next spring. Despite the injury, Torres gets the nod due to his elite pure hitting skills and success against advanced pitching. A case could also be made for the White Sox's Eloy Jimenez who has a potent power-patience combination to go along with a disciplined all-fields approach at the plate.

The Blue Jays’ Vladimir Guerrero, Jr. and the Rockies’ Brendan Rodgers would also be defensible choices for the top spot, but Vlad, Jr. is a mere 18 and just debuted at High-A, while Rodgers has cooled off in Double-A after blistering the hitter-friendly California League. In any event, there’s still plenty of prospect talent in the minors, and while no one individual stands out, there are a number of guys who project as future big league stars.

MLB Top Prospects: Likely September Call-ups in 2017

Dominic Smith (No. 17) is probably next in line for a call-up, but there are at least a dozen other guys on this list who could see major league action before the end of 2017. The departure of Lucas Duda opens the door for Smith to be the Mets’ regular first baseman. After adjusting his swing path this season in order to produce more power, Smith is looking like a high-average, 20-HR guy in the bigs.

The Rays’ Brent Honeywell (11) and the White Sox’ Reynaldo Lopez (25) are also likely to receive promotions in the next month or so. The Rays are still in the playoff hunt and Honeywell would be an upgrade for the back of the rotation, where his deep repertoire and nasty screwball would make him an above-average contributor even as a rookie. Lopez has put together a strong second half after struggling with consistency and command in the first half. If he can harness his explosive three-pitch mix, he could eventually pitch at the front of the South-Siders’ rotation.

The Phillies are all-in on a rebuild and will probably want to see what top prospects Scott Kingery (18), Rhys Hoskins (41), and J.P. Crawford (38) can do at the big-league level. Kingery has enjoyed a breakout year after making significant adjustments to his swing in the offseason. He probably won’t hit for average against advanced pitching, but a .265 average and 20 home runs are possible. Hoskins has plus power, but he will need to shorten his swing to reach his potential as league-average first-baseman in the majors. Crawford took some time off in June to work on his swing and the results have been encouraging – an improved contact rate and an increase in power. The Phillies might handle him with care and keep him the minors for the remainder of this season, but he’s starting to look like the shortstop of the future again for Philadelphia.

The Dodgers are in it to win it this season, meaning RHP Walker Buehler (12) and OF Alex Verdugo (20) could get call-ups if the team needs pitching or outfield depth for the stretch run. Given Buehler’s injury history, the club may want to limit his innings and have him pitch out of the bullpen, but he could also get a handful of starts down the stretch. Chris Taylor’s emergence in LA has dampened the Dodgers’ need for outfielders, but it’s still a thin depth chart and Verdugo is a polished, big-league ready hitter who could step in and produce right away.

The tight AL wild card race could result in an opportunity for the Rays’ Willy Adames (22) and the Yankees’ Chance Adams (46). Adames has cooled off after a mid-season hot streak, but his above-average defense and solid bat should be an asset for Tampa Bay this season. Adams has been a revelation as a starter this year and could be in line for some late-season starts in New York. Adams has solid command of three above-average pitches, which he’s used to dominate Triple-A hitters this year.

In the NL race, Colorado might turn to utility infielder Ryan McMahon (40), who has tightened his plate discipline and improved his swing path during an impressive campaign. batting .362 over 101 games split between Double-A and Triple-A. McMahon has above-average power and could produce 20-plus home runs over a full season in Colorado.

Others who might see big-league time this year are the Blue Jays’ Anthony Alford (31), the Orioles’ Chance Sisco (47) and the Cardinals’ Jack Flaherty (48). Alford made his big-league debut earlier this season but was felled by a hamate injury. Now healthy, he sports a modest power-speed package and solid on-base skills. Sisco is Baltimore’s catcher of the future and should grow into double-digit home run power to go with a present ability to hit for average to all fields. Flaherty has little left to prove in the minors and could a get a look in St. Louis, where his above-average four-pitch mix should allow him to eventually slot in the middle of the rotation.
