Rest-of-Season Projections
Brought up from minors
The Cardinals recalled O'Brien from Triple-A Memphis on Friday.
ANALYSIS
He'll absorb the roster spot vacated by Ryan Fernandez, who was optioned to Memphis. O'Brien has yielded three earned runs while striking out 14 over seven innings with Memphis this season. He'll look to help out a struggling St. Louis bullpen.

Latest Fantasy Rumors
Eligible for promotion Monday
O'Brien will be eligible to be recalled by the Cardinals on Monday, and Jeff Jones of the Belleville News-Democrat speculates the right-hander could be called up from Triple-A Memphis at some point this week.
ANALYSIS
O'Brien could have joined the Cardinals over the past couple weeks if the corresponding move was an IL transaction, but he's stayed a Triple-A for the full 15 days. The 29-year-old has made just one appearance in the majors this season but has been dominant in 13 outings for Memphis with a 1.46 ERA, 0.99 WHIP and 9:5 K:BB over 12.1 innings.
