Leahy has generated "intrigue" as a potential option for the Cardinals' rotation, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

All 76 of Leahy's appearances in the majors have come from the bullpen, and he has been used almost exclusively as a reliever since 2023. However, he has lots of past experiences as a starter in the minors, and many of his relief appearances have spanned multiple frames, including his last time out Tuesday in Colorado when he struck out seven while yielding one run over 3.2 innings. It does not sound like a move to the Cardinals' rotation is imminent for Leahy, but it could be considered if they trade other members of the rotation at the deadline. Leahy has posted a 2.95 ERA and 48:19 K:BB over 55 frames in 2025.

Leahy has posted a 6.52 ERA and 6:5 K:BB over 9.2 innings covering his last nine appearances.

EDGE Analysis

Leahy still holds a 2.48 ERA for the season thanks to his great start, but a 3.73 FIP and 27:12 K:BB across 36.1 innings paint a less flattering picture. The 28-year-old collected 12 holds through his first 23 appearances but has zero across his last six outings.

Leahy is set to see more high-leverage relief appearances for the Cardinals, Katie Woo of The Athletic reports.

EDGE Analysis

Leahy is off to an excellent start, having allowed just one run and one hit with a 10:3 K:BB over 7.2 innings. He looks to have leapfrogged Ryan Fernandez -- who has a 10.80 ERA -- in the pecking order among righty relievers for St. Louis, at least for the time being. While he's unlikely to garner any save chances, Leahy could be worth a look in leagues that count holds.

Leahy has spun eight scoreless innings with a 9:1 K:BB during Grapefruit League play this spring.

EDGE Analysis

Leahy is competing with Nick Anderson, Chris Roycroft and Riley O'Brien for one of the final two spots in the Cardinals' Opening Day bullpen. Perhaps working in Leahy's favor, in addition to his fine work this spring, is that he's shown the ability to go multiple frames, whereas the other three competitors are more one-inning relievers. Each of Leahy's last three outings this spring were two innings apiece, and he recorded more than three outs in 20 of his 33 appearances last season for St. Louis.

The Cardinals recalled Leahy from Triple-A Memphis on Saturday.

EDGE Analysis

Leahy owns a 4.02 ERA and 1.02 WHIP through 47 innings with the Cardinals this season, and he's given up just one earned run across 5.2 Triple-A frames since making his last MLB appearance Sept. 6. He'll come up to give the Cards some additional bullpen depth as Sonny Gray (forearm) heads to the IL.

The Cardinals optioned Leahy to Triple-A Memphis on Saturday.

EDGE Analysis

Leahy has turned in a 4.30 ERA and 0.95 WHIP over 14.2 innings since being recalled from the minors in late-July, though he'll now be sent back to Triple-A after giving up three runs over 1.1 frames during Friday's loss. Chris Roycroft was recalled from Memphis in a corresponding move.

The Cardinals recalled Leahy from Triple-A Memphis on Sunday.

EDGE Analysis

The move corresponds with the Cardinals designating right-hander Giovanny Gallegos for assignment. Leahy's last major-league outing was July 21 against Atlanta, when he pitched two scoreless innings and notched his first major-league save. Across 19 major-league outings this season, Leahy has a 3.90 ERA and 1.05 WHIP across 32.1 innings.

Leahy was optioned to Triple-A Memphis on Sunday.

EDGE Analysis

Leahy recorded a save in the second game of Saturday's doubleheader, allowing a hit and striking out two over two scoreless innings. The right-hander has been the Cardinals' preferred 27th man for doubleheaders and has also seen some occasional time as a low-leverage option in the bullpen this season, so he should be at the top of the list if the team needs an injury replacement in the majors.

Leahy recorded his first career save in the second game of Saturday's doubleheader split with Atlanta, giving up a hit and striking out two over two scoreless innings.

EDGE Analysis

The 27-year-old righty was called up to be the 27th man for the twin bill, and he surprisingly got the nod in a high-leverage spot with St. Louis winning 6-5 in the eighth inning. When the Cards tacked on three more runs in the top of the ninth. manager Oliver Marmol elected to leave Leahy on the mound to clean things up. He hasn't pitched poorly during his time on the big-league roster this season, posting a 3.90 ERA, 1.05 WHIP and 22:7 K:BB through 32.1 innings over 19 appearances, but Leahy's likely headed back to Triple-A Memphis despite this performance.

Leahy is with the Cardinals and will be the team's 27th player for the nightcap of Saturday's doubleheader against Atlanta, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

Leahy will give the Cardinals and additional bullpen arm for Game 2 after St. Louis lost 3-2 in 10 innings during the matinee. Leahy has thrown 30.1 big-league innings with a 4.15 ERA and 1.09 WHIP. He'll likely be sent back to Memphis following the contest.
