Ohtani homers for 1,000th hit and strikes out 8, but Cardinals rally past Dodgers 5-3

Shohei Ohtani homered for his 1,000th career hit and struck out a season-high eight in four innings on the mound, but the St. Louis Cardinals rallied to beat the Los Angeles Dodger...

Locks down first save O'Brien earned the save in Wednesday's 5-3 win over the Dodgers, issuing one walk over 1.1 scoreless innings.
Impact After Freddie Freeman singled with two outs in the eighth inning, O'Brien was called upon to set down Teoscar Hernandez to end the frame. The right-hander would come back out for the ninth, where he'd work around a two-out walk to earn his first major-league save. After allowing 10 earned runs in eight innings last season, O'Brien has emerged as one of the Cardinals' top bullpen options this year, posting a 1.84 ERA with a 1.19 WHIP and 29:14 K:BB across 29.1 innings. O'Brien should be in line for additional save chances down the stretch following the departures of Ryan Helsley and Phil Maton at the trade deadline.

Excelling out of St. Louis bullpen O'Brien has permitted just one run and boasts a 20:8 K:BB over 16 innings covering his last 12 appearances.
Impact O'Brien has had trouble staying healthy and producing at the major-league level, but the stuff has always been there and he seems to finally be finding his footing. The 30-year-old netted his second hold of the season in Sunday's win over Atlanta and could continue to be elevated in the Cardinals' bullpen hierarchy.

Cardinals option RHP Fernandez to Triple-A Memphis and recall RHP O'Brien

APRIL 25, 2025 • Associated Press
Brought up from minors The Cardinals recalled O'Brien from Triple-A Memphis on Friday, Katie Woo of The Athletic reports.
Impact It's unclear what the corresponding roster move will be. 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.

Optioned to Triple-A The Cardinals optioned O'Brien to Triple-A Memphis on Saturday.
Impact 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.

Returns from elbow issue O'Brien tossed a scoreless inning Friday versus the Mets after being unavailable for more than two weeks due to right elbow soreness, Derrick Goold of the St. Louis Post-Dispatch r...
Impact O'Brien said his elbow "flared up" after his second spring outing on Feb. 26, but he did not go for tests because the elbow responded immediately to rest and treatment. While the reliever was unconcerned about the issue, it should be noted that he missed much of the 2024 campaign with a flexor strain. The Cardinals will wait to see how O'Brien's elbow bounces back from Friday's appearance before scheduling his next outing. O'Brien is in the running for one of the final spots in the St. Louis bullpen.
