Frankie Montas (RHP)
10/16: Montas was acquired this summer by the A’s from the Dodgers in the Josh Reddick/Rich Hill trade, and he actually comes with a bit of major league experience on his resume. He made 7 appearances with the White Sox in 2015 before being dealt to the Dodgers prior to the 2016 season. Surgery last offseason followed by a broken rib sidelined Montas for all but 7 games this year. The Dominican righty boasts a 100+ mph fastball and has struck out an average of 9.3 batters per 9 innings over his minor league career. Montas has mainly appeared as a starter in the minors. And if he looks strong in his return to action, it’s possible that he could compete for a rotation spot next spring, or the A’s could always choose to put his power arm in the bullpen and see how it plays out there.
Trey Cochran-Gill (RHP)
10/16: The reliever came to the A’s from the Mariners in return for Evan Scribner as part of Oakland’s offseason bullpen purge. Originally taken by the Mariners in the 17th round of the 2014 draft, the 23-year-old had failed to allow a home run in his minor league career prior to this past season. The Alabama native was especially tough on right-handers while coming out of Midland’s bullpen in 2016 and had a stretch of 3 ½ months this season where he didn’t surrender a round-tripper for the RockHonds.
Sam Bragg (RHP)
10/16: The A’s 18th-round pick in the 2013 draft, the right-handed reliever has always had good control and solid strikeouts numbers. Bragg got off to a rough start in 2016, but he finished strong and ended up striking out 68 while walking just 19 over 65 innings for Midland. The right-hander had equal success against righties and lefties for the RockHounds, but he’ll be looking to gain greater overall consistency.
Daniel Mengden (RHP)
9/16: Mengden is set to be the first pitching prospect called up by the A’s with September’s expanded rosters. He looked impressive in his first 4 outings for Oakland this season, allowing just 8 earned runs over 4 starts in June, but he struggled in his next 5 appearances, giving up a total of 23 earned runs in 5 July starts before being sent back to Nashville. Mengden impressed after returning to Music City, putting up a 2.10 ERA in 6 starts for the Sounds. And overall, in 17 minor league starts this season, Mengden has posted an impressive 1.46 ERA while striking out 95 in 98 1/3 innings of work. The 23-year-old admittedly was feeling a little worn down after hitting a career-high in innings pitched this season. But after a little R & R in the offseason, if Mengden can return to the form he flashed in his first 4 big league starts, then he could put himself in contention for a return to the majors again next season.
Dillon Overton (LHP)
9/16: Overton made 5 starts for Oakland this season and mostly struggled, putting up a 10.97 ERA in his time with the A’s. But he was one of the best starters in the Pacific Coast League this season. His 3.29 ERA is currently the fifth best in the league and he’s struck out 105 in 125 2/3 innings for the Sounds. There’s obviously a big difference between what it takes to succeed at Triple-A and what it takes to make it in the majors. The A’s have been hoping that Overton’s velocity would tick up another notch since his return from Tommy John surgery. And if he could manage to add just a couple miles an hour to his fastball next season, it could make a world of difference. It’s also possible that the A’s front office could ultimately decide that Overton’s arm is better-suited to the bullpen and could take the opportunity to see how he fares as either a long reliever or a situational lefty.
Jharel Cotton (RHP)
9/16: After coming to the A’s as part of a trio of talented young arms the team snagged from the Dodgers in the Josh Reddick/Rich Hill deal, Cotton made a strong impression when he came within one out of throwing a perfect game in his second start for Nashville. The 24-year-old has posted a 2.86 ERA in 6 starts for the Sounds and appears poised to claim the Pacific Coast League strikeout crown with 155 K’s in 135 2/3 innings of work this season. Cotton has consistently tallied big strikeout totals. His mid-90s fastball and his solid changeup have enabled him to succeed at the Triple-A level and, with a strong spring, he could put himself into contention for a spot in the major league rotation next season.
Raul Alcantara (RHP)
9/16: Alcantara has been a prominent pitching prospect in the A’s system since coming over from the Red Sox, along with Josh Reddick, following the 2011 season. Tommy John surgery slowed down his progress, but he’s made quite an impression in the second half this season, putting up a 1.18 ERA in 8 starts since joining Nashville in July. He’s yet to have a bad start at the Triple-A level, and it appears that Alcantara could finally be reaching his potential. He’s still just 23, but he’s been on the A’s 40-man roster for some time, so his option years are winding down, and the A’s may feel some pressure to give him a shot soon. He’s pitching as well as anyone at Nashville right now. So why not strike while the iron is hot? And Alcantara’s arm has certainly been as hot as anyone’s in the second half of 2016.
Sean Manaea (LHP)
8/16: The former 1st-round draft pick for the Royals was expected to spend most of the season at Triple-A. But due to injuries, Manaea was called up after making just 3 starts for the Sounds, and he’s now made 20 apperances so far for the A’s. The Samoan southpaw has struck out 100 in 117 1/3 innings for Oakland this season and has gotten stronger as the season has worn on, posting a 3.58 ERA in the second half. The A’s parted with former prospects Daniel Robertson and Boog Powell in the deal that originally brought Zobrist to Oakland. When the team turned around and acquired a top pitching prospect like Manaea in return for Zobrist, it added a high-ceiling young arm to the system. And it looks like the big strike-throwing lefty should prove to be a staple of the A’s starting rotation in the coming years.
Grant Holmes (RHP)
8/16: A former 1st-round draft pick for the Dodgers in 2014, Holmes was a highly-coveted high school arm who is the highest-profile hurler to come to the A’s in the recent deal with the Dodgers. As a young 20-year-old in the hitter-friendly High-A California League, Holmes had fared well for the Dodgers’ affiliate this year, posting a 4.02 ERA while striking out 100 over 105 1/3 innings of work before the trade. But Holmes has struggled since coming to Stockton, surrendering 19 earned runs over his first 19 innings while pitching for the Ports. He’d just passed his career-high in innings pitched prior to the trade, so he could just be a little worn down late in the season while also making the adjustment to a new organization. Holmes is a big strong kid who has averaged 9.3 strikeouts per 9 innings over his minor league career and has to be considered one of the top young pitching prospects in the A’s system at this point.
Casey Meisner (RHP)
8/16: Meisner came to the A’s in the least high-profile of last summer’s deals, in return for reliever Tyler Clippard. A former 3rd-round draft pick for the Mets, Meisner got off to a great start for Stockton, posting a 2.78 ERA in 7 late-season starts for the Ports. He returned to the California League this year but has mostly struggled this time around the track, putting up a 4.59 ERA over 113 2/3 innings. The 6-foot-7 righty’s mechanics can be an issue and his command has been inconsistent this season. But Meisner’s been walking far fewer in the second half, and he’s still just 21. So even if he may not currently be considered among the team’s top prospects, Meisner still possesses a lot of potential.
A.J. Puk (LHP)
8/16: Widely reported to be a possible #1 pick in this year’s amateur draft, the A’s were thrilled to get their hands on a top pitching prospect like Puk with their first pick in the draft. Puk is a flame-throwing lefty out of Florida with top-of-the-rotation potential. The 6-foot-7, 220-pound power pitcher’s fastball has been clocked as high as 99 mph, and he pairs it with a solid slider. Since joining Vermont, Puk’s struck out 34 in 28 2/3 innings while posting a 3.14 ERA for the Lake Monsters. And with his outstanding fastball, a solid slider, an impressive frame and loads of raw talent, it’s easy to see why most people view Puk as a pitcher with tremendous upside and a player who could make a real difference for the green and gold before long.
Daulton Jefferies (RHP)
8/16: With their second selection in the competitive balance portion of the 1st-round of this year’s draft, the A’s took the talented young righty out of UC Berkeley. Jefferies’ fastball has been clocked as high as 95 mph, and he also features a slider and an occasional changeup while possessing excellent command. Despite being sidelined for eight weeks during his final college season with shoulder and calf injuries, Jefferies went 7-0 and posted a stellar 1.08 ERA while striking out 53 and walking just 8 over 50 innings of work for Cal. The A’s took things slow with Jefferies after the draft due to his previous shoulder injury, but he’s recently started seeing some action in Arizona. And in his first 4 brief appearances, the 21-year-old has shown off his pinpoint control by allowing just 1 walk and 1 run while striking out 12 over 8 2/3 innings for the AZL A’s.
Logan Shore (RHP)
8/16: With the A’s 2nd-round pick in this year’s draft, the team took one of Puk’s college teammates from Florida, who recently joined his old friend at Vermont. Shore is a 6-foot-2, 215-pound righty who went 11-0 with a 2.44 ERA while striking out 80 and walking just 15 over 92 1/3 innings of work in his last season for Florida. The 21-year-old was actually the top performer on Florida’s pitching staff, while Puk was considered to have more upside. Shore doesn’t throw nearly as hard as the A’s top two picks but is a consistent strike-thrower with good control who also possesses an advanced changeup. What he may lack in velocity, he more than makes up for with solid command and an advanced understanding of pitching that many expect will help him rise quickly through the system. In his first 5 appearances for Vermont, Shore has allowed 3 earned runs and struck out 9 over his first 12 innings of work.
