The Cardinals have placed reliever Trevor Rosenthal on the 10-day DL with what the team is calling right posterior elbow irritation, per an announcement. Young righty Luke Weaver has been recalled to take his spot on the active roster.
Rosenthal had recently regained the team’s closer role, turning in quality results as the Cards surged in the standings. But the hard-throwing righty left last night’s outing after exhibiting diminished velocity, with indications at the time that he was experiencing tightness in his pitching arm.
The 27-year-old hurler has turned in a bounceback year after a rough 2016 campaign that was marred by arm problems. Through 47 2/3 innings to date, he carries a 3.40 ERA and has racked up 14.3 K/9 against 3.8 BB/9. Rosenthal has not only reversed last year’s walk problems, but has worked at a career-high 98.9 mph and generated a personal-best 15.9% swinging-strike rate.
