Jason Kipnis isn't the player who recently got a promotion.
Josh Satin (Mets) was finally promoted to AAA. That was long overdue. In AA this season, Satin had a line of .325/.422/.535 for an OPS of .957 in 404 PAs.
Ben Guez (Tigers) has put up decent numbers in AAA, with a line of .284/.344/.413 for an OPS of .757 in 222 PAs. Between AA and AAA this season, his line is .302/.366/.475 for an OPS of .841 in 338 PAs.
Since being called up to AAA, Ryan Lavarnway (Red Sox) has been on a tear. His line in AAA is .381/.450/.769 for an OPS of 1.219 in 151 PAs. Between AA and AAA this season, his line is .322/.395/.611 for an OPS of 1.006 in 390 PAs.
Of the three players above, I think Lavarnway has the best chance of being a September call-up.
Don't sleep on Michael Schwimer, either. He has been dominant at AAA this season for the Phillies. He is 5-1 with 8 saves and has a 1.82 ERA, a 1.067 WHIP, 6.6 H/9, 0.5 HR/9, 3.0 BB/9, 11.4 K/9, and 3.83 K/BB in 54 1/3 innings.
Dylan Axelrod (White Sox) has split time between AA and AAA this season and has also been very good as a starter. In 16 starts and 18 appearances, he is 5-2 with a 2.97 ERA, a 1.11 WHIP, 8.0 H/9, 0.1 HR/9, 2.0 BB/9, 8.5 K/9, and 4.27 K/BB in 100 innings.
Batting 6th, Danny Valencia was 1-3 with 1 BB, 1 HR (his 12th), 1 RBI, and 2 runs scored against the Tigers.
Batting 3rd, Ryan Braun was 1-3 with 1 BB, 1 HR (his 19th), 1 RBI, and 1 run scored against the Giants. Braun needs just 1 more HR and SB for his 2nd career 20/20 season. And the way he's going this year, a 30/30 season isn't out of the question.
Batting leadoff, Ian Kinsler was 1-4 with 1 double (his 24th) and 1 run scored against the Blue Jays. Kinsler also has a good chance at reaching 20/20 for the 3rd time in his career. He needs 5 more HRs and 1 more SB.
Batting cleanup, Kevin Youkilis was 0-4 against the Mariners.
Pinch hitting, Sam Fuld was 0-1 against the Royals. With Desmond Jennings being recalled, one would expect Fuld's playing time to go down. Of course, if B.J. Upton is traded, that's another story.
Craig Breslow picked up his 7th hold of the season. He pitched 2/3 of an inning on 1 hit and 1 K against the Yankees.
