The Cardinals traded Helsley to the Mets on Wednesday in exchange for Jesus Baez, Nate Dohm and Frank Elissalt, Jeff Passan of ESPN.com reports.

EDGE Analysis

After making a move for Tyler Rogers earlier in the day, the Mets will bring in another quality high-leverage arm in Helsley, who currently boasts a 3.00 ERA through 36 innings and has notched 21 saves this season. With Edwin Diaz already firmly established as the Mets' closer, Helsley will likely join Rogers in working as a setup man in Queens.

Helsley was awarded the save Friday against the Padres, allowing one hit and striking out two in a scoreless ninth inning.

EDGE Analysis

Called upon to protect a three-run lead, Helsley worked around a single to notch his 21st save of the season and second in as many nights. While the 31-year-old has had some hiccups this year, converting 21 of 26 save opportunities, he's been sharp recently, giving up just one earned run across his last 10 appearances, as the Cardinals continue to lean on him in high-leverage spots.

Helsley struck out two and allowed a hit in a scoreless ninth inning to earn the save Thursday against the Padres.

EDGE Analysis

The right-hander picked up his first save since July 13 and has converted seven straight chances, giving up just one earned run across his past 10 appearances. In 2025, Helsley has rarely looked like the closer that led the league with 49 saves last season, but he's still expected to garner significant interest on the trade market with a 3.09 ERA, 1.40 WHIP and 39:14 K:BB over 35 innings this year.

Helsley allowed a hit and a walk in a scoreless inning while earning a save against Atlanta on Sunday. He struck out one batter.

EDGE Analysis

After blowing three straight chances in early June, he's converted six straight while allowing only one run over his last eight outings. Helsley owns a 3.27 ERA and a 36:14 K:BB while converting 19 of his 24 save chances this season.

Helsley notched the save in Tuesday's 4-2 win over Washington, allowing one hit and one walk with no strikeouts in a scoreless ninth inning.

EDGE Analysis

Helsley picked up save No. 18 on the campaign, and he's now tied with three other relivers for the fourth-highest mark in this area in the National League. The 30-year-old right-hander had a very shaky stretch to open June, during which he allowed one run in four consecutive outings to begin the month, but he's since settled back in nicely. Over his last six appearances, Helsley hasn't yielded a run while converting each of his five save chances.

Helsley struck out one and didn't allow a baserunner in a scoreless ninth inning to earn the save Saturday against the Cubs.

EDGE Analysis

Helsley recorded a save against the Guardians on Saturday, striking out one batter in a perfect ninth inning.

EDGE Analysis

Helsley got a relatively easy save chance, as he entered in the ninth inning with St. Louis holding a three-run lead. He came through with a stress-free frame, retiring all three batters he faced on 11 pitches. This was Helsley's third straight scoreless appearance following a rough stretch to begin June in which he gave up at least one earned run in four consecutive outings. While he's had some struggles this season, Helsley is tied for 11th in the majors with 16 saves in 21 opportunities.

Helsley picked up the save in Tuesday's 8-7 victory over the Cubs, allowing two hits in a scoreless ninth inning. He struck out one.

EDGE Analysis

June has certainly been a dicey stretch for Helsley, who's now yielded two knocks in five of his seven outings this month, but he was able to hang on for his 15th save Tuesday. The hard-throwing right-hander had blown three straight save opportunities prior to successfully converting his past two chances, so that should offer fantasy managers some optimism going forward. Helsey sports a 3.54 ERA and 33:12 K:BB over 28 innings, but his 1.46 WHIP looms as a cause for concern.

Helsley earned the save in Game 1 of Thursday's doubleheader against the White Sox, striking out one in a perfect ninth inning.

EDGE Analysis

Helsley was called upon to protect a 5-4 lead in the ninth and needed just 10 pitches to secure his first save since May 31. It was an encouraging outing for the 30-year-old, who had blown three straight save chances and allowed a run in each of his previous four June appearances. On the season, he's 14-for-19 in save opportunities with a 3.81 ERA, 1.50 WHIP and 31:12 K:BB across 26 innings.

Helsley dealt with a toe injury on his right foot early in the season that required an uncomfortable insert in his cleat, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

The toe issue -- which first cropped up late in spring training -- threw off Helsley's delivery, resulting in less velocity and command. Helsley finished April having allowed four runs with a 10:8 K:BB over 10 innings. The 30-year-old suffered a third straight blown save Monday against the Blue Jays, but Helsley said he feels "great" now, and his velocity is back up, giving him confidence he can bounce back.
