The St. Louis Cardinals called up 22-year-old pitching prospect Trevor Rosenthal from Double-A Springfield on Monday, but Cardinals general manager John Mozeliak doesn't want fans to think it's a panic move for the bullpen. Rosenthal posted the second-best ERA in the Texas League (2.78 ERA) over his 94.0 innings of work, and he also racked up the fifth-highest strikeout total in the league (83 strikeouts) while walking just 37 batters. For Mozeliak, that simply made Rosenthal the best internal option, as he told Joe Strauss of the St. Louis Post-Dispatch:
"Clearly we're still developing roles and trying to get things to become more successful. When you look at our internal options, we thought most about giving Rosenthal a chance."
When Rosenthal takes the mound for the Cardinals it will be his MLB debut. Back in February, ESPN's Keith Law ranked Rosenthal as the team's No. 7 overall prospect and fifth-best pitching prospect in the organization.
