Kyle Zimmer is going back to school.
On Friday, the Royals announced they were shutting down Zimmer two days after he experienced shoulder stiffness in his start with Class AA Northwest Arkansas.
“Kyle has some minor shoulder irritation and has reached his innings threshold for the season, so he will no longer pitch in 2013,” Royals director of player development Scott Sharp told MLB.com. “He is returning to school for the fall semester to rest and knock out some classes, and will return ready to go in 2014.”
Zimmer, the Royals’ first-round pick in last year’s draft from the University of San Francisco, started this season with Class A-Advanced Wilmington, where he went 4-8 with a 4.82 ERA. He struck out 113 and walked 31 in 89 2/3 innings.
In his last five starts with the Blue Rocks, Zimmer was 3-2 with a 2.59 ERA and 42 strikeouts in 31 1/3 innings. He gave up 21 hits and walked six in that span.
That earned Zimmer, 21, a promotion to the Naturals, where he was 2-1 with a 1.93 ERA and 27 strikeouts against five walks in 18 2/3 innings.
His combined totals: a 4.32 ERA, 140 strikeouts and 36 walks in 108 1/3 innings.
