Optioned to Triple-A
The Cardinals optioned O'Brien to Triple-A Memphis on Saturday.
ANALYSIS
O'Brien made his return Friday from an elbow issue that held him out for two weeks, but he'll now head back to Memphis to begin the 2025 campaign. The 30-year-old righty owns a 10.45 ERA over 10.1 career MLB innings, though St. Louis may be willing to give him another shot if he can replicate his 1.35 ERA in Triple-A from last year.

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.
