The full extent of Doolittle's oblique injury remains uncertain, but it appears he is set to miss at least the next couple weeks due to the setback. Luke Gregerson appears to be the top option to see the ninth-inning duties in Doolittle's absence.

Doolittle (oblique) underwent an MRI on Sunday, Susan Slusser of the San Francisco Chronicle reports.

Doolittle hasn't shown much improvement from the cramping in his oblique a night earlier, so the Athletics will examine him more closely to see if he's dealing with an intercostal strain. If the MRI indeed reveals a serious oblique injury that results in a DL stay, manager Bob Melvin said he would decide on a fill-in closer rather than using a committee. Luke Gregerson would seem to be the top candidate to take his spot at the back of the Oakland bullpen.

Doolittle (oblique) felt a cramp in his right side after the second-last pitch of Saturday's game against the Angels, Jane Lee of reports. However, he is feeling better, passed some initial tests, and isn't worried it's anything serious.

Excellent news for fantasy owners and the A's, who just grabbed a share of the AL West lead with the Angels with Saturday's win. It sounds like he should be fine but will enjoy an off day Sunday after pitching two days in a row. Barring any setbacks, it should be safe to get "The Doctor" back in your lineup Monday.

Doolittle slammed the door for his 20th save of the season Saturday against the Angels, allowing a single and striking out one. However, he appeared to be in some discomfort after fielding a ground ball for the final out of the game, and was seen on camera saying "yeah" when catcher Daniel Norris asked him, "oblique?"

Owners will need to sit tight waiting for more information to surface about Doolittle and if, in fact, he suffered some sort of injury Saturday. Oblique and abdominal issues can vary widely from minor stiffness that can be played through to more major strains or tears that require long-term stints on the DL, so keep your fingers crossed. Either way, there's a good chance he gets a rest Sunday as the closer has pitched two days in a row.
