What happened. The St. Louis Cardinals purchased the contract of RHP Jack Flaherty, RHP Sandy Alcantara, and C Alberto Rosario as well as called up OF Harrison Bader and IF Alex Mejia. To make room on the 40 man roster, LHP Sean Gilmartin was outrighted.
The story. The Cardinals made their first wave of September callups today. We already knew about Flaherty, as he had already been announced as today’s starting pitcher against the Giants, however, the rest were unknown but not unexpected additions.
The numbers. Jack Flaherty, 21, is a former first round pick of the Cardinals from the 2014 MLB Draft. Through the minors, he has been dominant, holding a 2.77 ERA over 400 innings in four seasons and five different levels of the minors. This season, he started the year posting a 1.42 ERA in 10 starts for Double-A Springfield before a promotion to Triple-A Memphis where he posted a 2.74 ERA in 15 starts.
He has thrown 149 innings so far this season and is likely going to be pushed as far or a little further than the club would like to, but it is a heavier workload for a minor league starting pitcher than I can remember in recent years. For comparison, the most Carlos Martinez ever threw in a season in the minors was 104 innings. For Alex Reyes it was 109.
Sandy Alcantara, 22 next week, was an international signing by the Cardinals. He had a 4.31 ERA in 22 starts and 3 relief appearances for Double-A Springfield. Alcantara boasted a 11.2 K/9 in two stops last season, but it has tumbled to 7.6 K/9 this season. The Cardinals are hoping he can be 2017’s Alex Reyes and turn that electric fastball into a quality bullpen arm.
Alberto Rosario, 30, has hit .247/.291/.279 in 50 games in Triple-A Memphis. He joined the club as a minor league free agent in December 2014. He spent time on the club’s 40 man roster last season, hitting .184 in 20 games with the big league club.
Alex Mejia, 26, will be the fourth member of the Cardinals’ 2012 draft class on their roster this September. The shortstop is up for his second stint with the big league club, having spent a couple weeks with the team hitting .214 in 10 games with the club including almost single-handed winning a game by himself. He has hit .291/.341/413 with 7 home runs in 118 games between Springfield and Memphis this season.
Harrison Bader, 23, was a third round pick of the Cardinals from the 2015 draft. He spent a week with the big league club earlier this season and hit .286/.348/.381 including scoring the walk off game winning run in his MLB debut. He hit .283/.347/.469 with 20 home runs in 123 games for Triple-A Memphis this season.
The impact. 8/10. Normally I wouldn’t consider September callups to be all that important to the club, but this is a unique place for the Cardinals to be.
They traded away Mike Leake to create an opportunity for Flaherty in the rotation. He is penciled into the 2018 rotation at this point and a good showing will go a long way towards helping the Cardinals made a run at this wild card.
Additionally, Alcantara could be an intriguing boost to the bullpen. He has the electric fastball, but also struggles with command. Stop me if you’ve heard this one before. If, like Trevor Rosenthal and Alex Reyes before him, he can harness it and put in some quality innings, that can be a big impact for a bullpen that has struggled in important innings most of the season.
The addition of Bader could be intriguing for an offensive mix that really only has Tommy Pham as a consistent contributor. Dexter Fowler has a nagging injury, Randal Grichuk is streaky, and Stephen Piscotty has had a rough season. But he will have to hit the ground running in his early starts to elbow his way into additional playing time.
I don’t foresee Mejia or Rosario in a position to give the club much impact, but those three, if the club makes an unlikely run at the Cubs or a Wild Card spot, the three guys I mentioned probably played a big role.
