Notable September Call-Ups

Today’s flurry of transactions has been driven by September call-ups as teams look to expand their flexibility with expanded rosters. Only players who are on the 40-man roster can be activated, of course, meaning that several organizations have had to designate or outright players to clear roster space. On the activation side of the equation, we always see big name prospects reach the bigs in early September, though many of the game’s best big-league ready youngsters have already been elevated this year.

We already noted Hector Olivera’s promotion earlier today, and you can see all of the day’s promotions at the MLB.com Transactions page. Here are some more of the notable call-ups (for various reasons)…

• Zach Davies, Brewers — Acquired in the Gerardo Parra deal, Davies is heading into the Milwaukee rotation for his first big league action. The rebuilding Brewers figure to have multiple rotation spots open in the long-term, making Davies’ late audition one to keep an eye on. Be sure to check out the MLBTR Podcast episode featuring the young righty.
• Miguel Castro, Rockies — Another recent trade acquisition, Castro was one of the two main pieces (along with fellow righty Jeff Hoffman) who went to Colorado in exchange for Troy Tulowitzki. It’s not clear what role the Rockies have in mind in the near-term, but they’ll get an early look to see whether he will be a part of their plans for 2016.
• Dalton Pompey, Blue Jays — Pompey opened the season with a chance to solidify himself as Toronto’s everyday center fielder, but offensive struggles saw him slide all the way to Double-A. Pompey nonetheless rates as one of baseball’s best prospects, and he’ll again have the opportunity to show the Blue Jays that he can be a long-term piece.
• Javier Baez, Cubs — It’s been a difficult season for Baez, who has dealt with the tragic death of his younger sister and then a broken finger but hit well late in the year at Triple-A. Baez’s light-tower power and exceptional bat speed make him one of the game’s most intriguing power prospects, and a huge September could lead the Cubs to pencil him in as their second baseman in 2016.
• Joey Gallo, Rangers — Speaking of the game’s top power prospects, Gallo wowed the baseball world when he .260/.362/.580 with five homers through his first 14 big league games earlier this year. But, he went 6-for-37 with 22 strikeouts over his next 11 games and was optioned to Triple-A, where his struggles continued. Gallo posted a very three-true-outcomes batting line in 53 games there: .195/.289/.450 with a 39.5 percent strikeout rate in 228 plate appearances. He has as much power as anyone in baseball, but the strikeouts are a concern.
• Marco Gonzales, Cardinals — The 19th overall pick back in 2013, Gonzales debuted with the Cardinals in 2014 and tossed 34 2/3 respectable, if unspectacular innings. He’s dealt with injuries in 2015 and hadn’t pitched in the Majors this season prior to September. The Cards threw him right into the fire tonight, and things didn’t go well (four runs in 2 2/3 innings). Gonzales could be in line for a rotation spot next season, although with Adam Wainwright returning and Jaime Garcia’s option likely to be picked up, he could begin 2016 in Triple-A again.
• Rob Refsnyder, Yankees — Refsnyder had a nice season at Triple-A (albeit a bit light in the power department), and Yankee fans have been clamoring for him to inherit the everyday second base job for quite some time. A platoon with Stephen Drew may be more likely, but Refsnyder will get his first extended run on a big league roster this month and hope to impress the team as Drew heads into free agency.
• Trevor Cahill — Cahill joins the Cubs on a mission to show some semblance of the form he displayed from 2010-13 with the A’s and D-Backs, when he very much looked the part of a mid-rotation starter. Since that four-year stretch (when he notched a 3.72 ERA in 751 innings), Cahill has an ERA just under 6.00 and has been released by the Braves and opted out of a deal with the Dodgers after floundering in Triple-A as well. He’s still only 27.
• Matt Moore, Rays — Moore’s return from Tommy John was dreadful, but he flat out dominated Triple-A hitters following a demotion to get his control back in check. Moore had a 3.30 ERA in Triple-A but held hitters to a .207/.273/.333 batting line with a 43-to-8 K/BB ratio in 30 innings, including an Aug. 22 start in which 16 of the 18 outs he recorded came via strikeout.
• Andrew Bailey, Yankees — The right-hander was a young, ace closer for the Athletics but saw his career fall apart due to injuries after being traded to the Red Sox. He’s thrown well at Triple-A this year after joining the Yankees on a minor league deal, and he’ll now get his first chance at the big league level since way back in 2013.
• Allen Craig, Red Sox — Craig has fallen off the radar after three outstanding seasons with the Cardinals from 2011-13. He’s probably not in Boston’s long-term plans, but a nice September could make it a bit easier for the Sox to generate a little trade interest. Craig batted .274/.368/.350 in Triple-A this season, and while the average/OBP are nice, he had just 18 extra-base hits (14 doubles, four homers) in 399 PAs there.
• Rex Brothers, Wilin Rosario, Rockies — Formerly two key contributors for the Rockies, both have wilted recently, and both could be viewed as change-of-scenery candidates this offseason. Their September performances, for that reason, are worth keeping an eye on.
