While we highlighted Trevor Rosenthal with a Prospect Instinct 2012 spotlight earlier in the season it’s time to take another look. On July 16, 2012 the St. Louis Cardinals called up the RHP from Springfield in Double-A.
This makes the past two seasons quite a ride for Rosenthal. He began and ended 2011 in Low-A Quad Cities and we highlighted that in his Prospect Instinct 2012. He probably should have begun the 2012 season in High-A with the FSL Palm Beach Cardinals but the Cards brass liked his Spring Training so much that they skipped him right to Double-A.
His season to date has looked like this – He was 8-6 with a 2.79 ERA and 83 strikeouts to 37 walks in 93.1. The .197 BA Against and the 3.51 FIP suggest that the success is for real. Some regression due? Sure. But remember, he skipped one of the biggest development stops for Cardinals pitchers. But Coach Dennis Martinez told me even before the season started that “Rosenthal… he’s a different animal.” when I asked about the thought process to having Trevor skip High-A while even #1 prospect Shelby Miller spent a half a season there.
5. Trevor Rosenthal, RHP 5/29/1990 H: 6’2″ W: 190 - Rosenthal made the the biggest jump inside the Cards system in 2011. He sat just outside the Top 15 last season and is now viewed as one of the top arms in all of the minor leagues. That shows you how deep this system is in right handed starters. Rosenthal has a mid 90s fastball and touches 97. He uses a mid 80s slider as a put away pitch, but it was his change up that made the biggest strides in 2011. The Cardinals forced him to use it more with a mandatory minimum pitch count which actually had him pitching backwards and using it early in counts. Check back when we do a more extensive break down of Rosenthal’s pitch development in our Prospect Instinct series.
Our Instinct: Rosenthal has the 3 pitch mix to be a mid rotation starter and could be as much as a #2. He should move to the FSL sometime in 2012 where he’ll work with Carlos Martinez and coach Dennis Martinez. I can see him moving station to station and making his pro debut some time in 2014. This is going to be an aggressive ranking in some opinions. Not in ours.
And while the other venues are all finally catching up with who Rosenthal is by making him a 2012 Breakout Player, Rosenthal himself is ready to make his Major League debut.
Chances are good that he spends time in the pen and he has the pitch mix to be successful there, but the Cardinals should be thinking long term and eventually give him more time in the minor leagues to finish and refine his stuff. In the long run his 92-95 fastball and slider are enough for success in the bullpen, but his changeup has advanced more than enough to make him a valuable starter.
We wish Trevor Rosenthal the best of luck and say congratulations.
