Just as the Oakland A’s rotation was about to return to full health, another starter has gotten hurt.
The A’s placed pitcher Daulton Jefferies on the 15-day injured list retroactive to May 19 due to right arm nerve irritation, the team announced Friday.
Jefferies started the game Wednesday but felt tightness in his right biceps afterward and had an MRI, reported Matt Kawahara of the S.F. Chronicle. The rookie, who battled through an extensive injury history during his years in the minors, has made eight appearances this season for Oakland, throwing 39u2153 innings so far.
