JoJo Romero Fantasy Stats

St. Louis Cardinals left-hander JoJo Romero has been effective in high-leverage situations this season and stands as the clear handcuff to closer Riley O'Brien. Romero owns a 2.96 ERA and 1.17 WHIP with 26 strikeouts in 27 2/3 innings. While O'Brien has locked down the closer role, he has begun to struggle as of late, allowing 10 earned runs (11 total runs) with two blown saves over his last 11 innings. He also has closing experience from last season, when he shared the role with O'Brien down the stretch and converted eight of nine save opportunities. Overall, last summer, Romero posted a stellar 2.07 ERA with 24 holds while operating in a high-leverage role. For fantasy managers in standard saves leagues, Romero is a smart, low-cost speculative add as O'Brien's primary handcuff. For those in leagues that reward holds, Romero continues to hold high-end value as he should remain a go-to option in high-leverage spots.

Across 61 innings (65 games) in 2025, St. Louis Cardinals relief pitcher JoJo Romero posted a 4-6 record with a 2.07 ERA, 1.25 WHIP, 55 strikeouts, and eight saves. With former Cardinals closer Ryan Helsley now a member of the Baltimore Orioles, Romero is in the mix to close games in St. Louis along with fellow Cardinals relievers Riley O'Brien and Matt Svanson. Romero outperformed his peripherals in 2025, as he posted a middling 10.2% K-BB rate. His 3.49 xERA and 3.28 FIP, while strong marks, were both significantly worse than his 2.07 ERA. Still, Romero has been an effective setup man for multiple seasons in St. Louis and saw some work in the ninth inning down the stretch of the 2025 season. As a left-handed reliever, Romero could emerge as Cardinals manager Oli Marmol's preferred ninth-inning option against lefty-heavy portions of opposing lineups. Romero may be worth targeting late in fantasy drafts heading into 2026.

The Seattle Mariners have expressed interest in bolstering their bullpen and have been linked to St. Louis Cardinals reliever JoJo Romero. The Cardinals are currently in the midst of a "re-tool" as they shipped off starting third baseman Nolan Arenado to the Arizona Diamondbacks this week and have also been shopping infielder Brendan Donovan. According to Jeff Jones of the Belleville News-Democrat, the Mariners are among the teams that have shown interest in Romero. Last summer, Romero was quite effective in the St. Louis bullpen, logging 61 innings to the tune of a 2.07 ERA and a 1.25 WHIP. He tallied just 55 punchouts but was a go-to option in high-leverage situations as he earned 24 holds and eight saves. While Romero would not contend for saves in Seattle as Andres Munoz is slated to remain the closer, he could find value in deeper holds leagues, operating as the primary left-hander in setup situations.

St. Louis Cardinals relief pitcher JoJo Romero picked up his eighth save of the season in Monday's 6-5 win over the Giants. Romero came in to pitch the bottom of the ninth inning up by one and tossed a 1-2-3 inning with a strikeout. The Cardinals have used numerous relief pitchers in save situations over the last 30 days, with Romero seeing more than others. The 29-year-old has pitched well this season, going 4-6 with eight of nine save opportunities converted and 23 holds to go with a 2.09 ERA, a 1.24 WHIP, and an 8.06 K/9 rate in 60 1/3 innings of work. While he has been one of the better arms out of the bullpen for the Cardinals, his fantasy value for the final week will remain up in the air, given how the Cardinals have utilized their bullpen at the end of games recently.

St. Louis Cardinals relief pitcher JoJo Romero picked up his sixth save of the season in Tuesday's 2-1 win over the Athletics. Romero came in to pitch the top of the ninth inning up by one and delivered a 1-2-3 outing with a strikeout. The 28-year-old has been in the mix for save opportunities since the team traded away Ryan Helsley and he has pitched well, converting all three of his opportunities without allowing a run in the last 15 days. He has now converted all but one of his save opportunities this season with a 2.13 ERA, a 1.26 WHIP, and an 8.17 K/9 rate in 50 2/3 innings of work. He is worth a look in at least deep roto leagues at this time for fantasy managers still in need of saves.

St. Louis Cardinals reliever JoJo Romero closed out a 4-1 win over the Pittsburgh Pirates on Thursday to log his fifth save of the season. Romero allowed one hit and no runs in a 12-pitch ninth inning, extending his modest scoreless streak to five appearances. The Cardinals haven't named a closer since they traded Ryan Helsley to the New York Mets on July 30, but Romero has gotten the lion's share of the team's saves this month. The lefty has been effective regardless of role this year, having pitched to a 2.25 ERA (3.29 FIP) with a 1.29 WHIP, 45:22 K:BB, and 19 holds in 48 innings.

St. Louis Cardinals relief pitcher JoJo Romero recorded his fourth save of the season on Thursday in a 7-4 win against the Rays. He was dominant the appearance, locking down a two-inning scoreless save while allowing one hit and striking out three. This was the first time all season that the 28-year-old pitched two full frames in an outing, and he needed only 26 pitches to get the job done. He's now thrown four straight scoreless innings since suffering two straight losses on August 13 and 17, as he remains the go-to option in the ninth inning after the departure of Ryan Helsley.

St. Louis Cardinals reliever JoJo Romero recorded four outs on Sunday to secure a 3-2 win over the Chicago Cubs and collect his third save of the year. The left-hander had to work around three singles and a walk in his 1 1/3 innings, but he managed his 13th scoreless appearance in 14 tries since the beginning of July. Romero now has a microscopic 1.98 ERA with 38:18 K:BB and a 52.3% groundball rate over 41 innings. He should continue to receive save opportunities thanks to the departure of former Cardinals closer Ryan Helsley, whom they sent to the New York Mets at the July 31 trade deadline.

St. Louis Cardinals left-handed reliever JoJo Romero will remain in a closer committee in St. Louis after the team traded away closer Ryan Helsley to the New York Mets at last week's deadline. Romero should probably be considered the favorite for save chances the rest of the way -- he has two saves in the last three days for the Red Birds -- especially since he's the only lefty arm in the bullpen after Steven Matz was traded. In addition to Romero, Riley O'Brien and Kyle Leahy are the other candidates to see save chances for the Cardinals in the final two months of the season. The 28-year-old Romero came on to preserve the win in Monday's 3-2 victory over the Dodgers, striking out one in a scoreless inning while also giving up a hit and a walk. Romero hasn't been perfect in 2025, but he has 16 holds and now is the favorite for saves in a committee approach.

The St. Louis Cardinals are still deciding who will take over the closer role after they shipped relievers Ryan Helsley and Phil Maton away at this week's trade deadline, but president of baseball operations John Mozeliak said on Thursday that left-hander JoJo Romero was the top candidate. Mozeliak also mentioned that right-handers Riley O'Brien and Kyle Leahy should see their usage expand to late-inning setup roles. Rookie Gordon Graceffo could also be in the mix, but it appears that Romero will get the first crack at ninth-inning duties, immediately raising his fantasy appeal for those looking for saves late in the year. Romero, 28, doesn't have typical dominant closer stuff, but he has a nice 2.04 ERA (2.84 FIP), 1.19 WHIP and 35:15 K:BB in 35 1/3 relief innings for the Cards this year. He has only four career saves in six MLB seasons.
