Ogando will be reevaluated after his next bullpen session, but it appears that he may not return until after the All-Star break. Ogando may need more side sessions and at least one batting practice session before he goes on a medical rehabilitation assignment.
The Rangers will also likely want Ogando to make at least two starts in the Minors. If Ogando doesn't return until after the All-Star break, the Rangers will have less than two weeks to evaluate their starting rotation before the July 31 non-waiver Trade Deadline.
Rookie right-hander Justin Grimm started for the Rangers on Wednesday. It was the 30th start by a rookie for the Rangers this season, the most for any team in the Major Leagues.
