Rookie RHP Yonny Chirinos is expected to miss about a month after being diagnosed Thursday with mild strain of the flexor tendon in his right elbow.
That was actually good news after the rookie right-hander underwent an MRI and an examination by Rays orthopedist Dr. Koco Eaton as there was no structural damage.
Chirinos, 24, experienced pain and tightness Tuesday as he prepared to throw a between-starts bullpen session, and the Rays immediately put him on the 10-day DL.
Chirinos started the season with three scoreless appearances and earned the No. 4 spot in the rotation but is now 0-1, 3.71.
LHP Ryan Yarbrough would seem the most likely candidate to replace Chirinos in the rotation in the near term, with RHP Nathan Eovaldi targeting a May 22-24 return from arthroscopic elbow surgery.
