Archie Bradley, RHP, Arizona Diamondbacks
152 IP, 1.84 ERA, .215 BAA, 162/69 K/BB (26 GS)
Playoffs: (W) 7 IP, 7 H, 2 ER, 4/1 K/BB
Bradley turned in a ridiculous final month of the regular season at Double-A Mobile, going 6-0 with a 1.24 ERA, .189 BAA and 36/16 K/BB in 36.1 innings. The 21-year-old wasn’t always at his best, as he walked five or more batters twice during that span. However, the right-hander was on point in his Southern League playoff start, allowing two earned runs over seven innings.
Noah Syndergaard, RHP, New York Mets
117.2 IP, 3.06 ERA, .243 BAA, 133/28 K/BB (23 GS)
Playoffs: 6 IP, 7 H, 3 ER, 8/1 K/BB
Few pitching prospects have had a better overall season than Syndergaard, so it was disappointing that the 21-year-old finished the regular season with his worst start of the year (and career): 3 IP, 9 H (3 HR), 11 R (9 ER), 5/2 K/BB. However, the 6’6” right-hander returned to form in the first round of the Eastern League playoffs, as he allowed three earned runs with eight strikeouts over six innings. Syndergaard also touched 100 mph on a knee-high fastball to end the third inning.
Matt Wisler, RHP, San Diego Padres
136 IP, 2.78 ERA, .217 BAA, 131/33 K/BB (26 GS)
Playoffs: 6.1 IP, 2 H, ER, 4/3 K/BB
After six outstanding starts in the High-A California League, the Padres promoted Wisler to Double-A San Antonio where he registered a 3.00 ERA, .223 BAA and 103/27 K/BB ratio in 105 innings. The soon-to-be 21-year-old (Sept. 12 birthday) furthered his brilliant campaign by allowing one earned run on two hits over 6.1 innings against Corpus Christi in the Texas League playoffs.
Robbie Ray, LHP, Washington Nationals
142 IP, 3.36 ERA, .224 BAA, 160/62 K/BB (27 GS)
Playoffs: (W) 6.2 IP, 3 H, ER, 6/2 K/BB
After a disappointing 2012 season at High-A Potomac (105.2 IP, 6.56 ERA), Ray bounced back in a big way this year with a breakout season between Potomac and Double-A Harrisburg. In his start during the Eastern League playoffs, the 21-year-old worked 6.2 innings for the first time after tossing a complete-game shutout on July 11.
Neil Ramirez, RHP, Chicago Cubs
107.2 IP, 3.68 ERA, .207 BAA, 132/44 K/BB (22 GS)
Playoffs: (L) 3.1 IP, 5 H, 5 R (3 ER), 3/3 K/BB
Acquired by the Cubs as the PTBNL (player to be named later) in the Matt Garza trade, Ramirez made a strong first impression with his new team by tossing 4.2 one-hit innings in his debut with Double-A Tennessee. Unfortunately, poor defense made the 24-year-old a tough-luck loser in his only start in the Southern League playoffs.
Eddie Butler, RHP, Colorado Rockies
149.2 IP, 1.80 ERA, .180 BAA, 143/52 K/BB (28 GS)
Playoffs: 1-1, 7.2 IP, 9 H, 5 R (4 ER), 6/2 K/BB (2 GS)
The No. 46 overall selection in the 2012 draft, Butler put up stupid-good numbers this year in his full-season debut. After opening the season at Low-A Asheville, the 22-year-old made 13 starts for High-A Modesto before graduating to Double-A Tulsa. While he was dominant at the more advanced level (27.2 IP, 0.65 ERA, 25/6 K/BB), Butler was shaky in both of his Texas League playoff outings.
