Jonathan Heasley - MLB News, Rumors, & Updates

Headed for free agency Heasley (elbow) has become a free agent after passing through outright waivers.

Impact Heasley spent most of the 2026 season on the Rays' 60-day injured list with a stress reaction in his right elbow after he suffered the injury in his lone appearance with the big-league club in May. He has a career 6.04 ERA across 143 big-league innings.

NOVEMBER 2 • ROTOWIRE

Shuttled to 60-day IL The Rays transferred Heasley (elbow) from the 15-day injured list to the 60-day IL on Monday.

Impact Initially deactivated last Tuesday after being diagnosed with a right elbow stress reaction, Heasley still remains without a clear timeline for a return, but his move to the 60-day IL ensures he'll be shelved through at least July 27. In a corresponding 40-man roster move, the Rays selected outfielder Austin Slater's contract from Triple-A Durham.

JUNE 8 • ROTOWIRE

Placed on big-league IL Heasley was returned to the major-league roster and placed on the 15-day injured list Tuesday with a right elbow stress reaction.

Impact Heasley was outrighted to Triple-A Durham on Saturday, but because he suffered his injury during his time with the Rays, he'll be placed on the Rays' 15-day injured list and also reclaim a spot on the 40-man roster. The 29-year-old righty gave up five earned runs in four innings during his lone outing with Tampa and will likely be outrighted to Triple-A again once he's healthy.

JUNE 3 • ROTOWIRE

Outrighted to Triple-A Heasley cleared waivers and was outrighted to Triple-A Durham on Saturday, Marc Topkin of the Tampa Bay Times reports.

Impact Heasley had a brief stint with the big-league club this week, allowing five runs over four innings in an appearance May 27. He was was DFA'd on Friday and is now back with Durham. Heasley has a career 6.04 ERA over 143 major-league regular-season innings, so he's likely to be used as bullpen depth for when the big club needs an extra arm.

MAY 30 • ROTOWIRE

DFA'd by Tampa Bay The Rays designated Heasley for assignment Friday, Marc Topkin of the Tampa Bay Times reports.

Impact Tampa Bay is bringing up a fresh arm in Andrew Wantz, who had his contract selected from Triple-A Durham in a corresponding move. Heasley threw 64 pitches across four innings of relief in Wednesday's 11-2 loss to the Orioles, allowing five runs on eight hits with two strikeouts.

MAY 29 • ROTOWIRE

Moves up from Triple-A The Rays selected Heasley's contract from Triple-A Durham on Wednesday.

Impact Heasley had been serving as a swingman at Durham this season, making seven appearances (four starts) while logging a 3.90 ERA and 1.21 WHIP across 27.2 innings. Though he could eventually be an option in the Tampa Bay rotation, for the time being, Heasley is expected to settle into a bullpen role. He'll give the Rays another arm who's capable of covering multiple innings after Tampa Bay placed Jesse Scholtens (wrist) on the 15-day injured list Tuesday.

MAY 27 • ROTOWIRE

Signs with Royals Heasley signed a minor-league contract with the Royals on Tuesday.

Impact Heasley has been a free agent since the White Sox released him at the end of March and hasn't pitched in a game at any level this season. The 28-year-old righty owns a 5.89 ERA and a 1.47 WHIP through 139 career innings in the majors and will likely serve as organizational depth for Triple-A Omaha.

AUGUST 6, 2025 • ROTOWIRE

Sent to minor-league camp The White Sox reassigned Heasley to minor-league camp Monday.

Impact Heasley, 28, attended camp as a non-roster invitee after he had previously turned in a 5.89 ERA and 89:55 K:BB in 139 career innings in the big leagues over parts of the last four seasons. Though he was sharp over his four Cactus League appearances in allowing just two hits and two walks while striking out three over four scoreless frames, Heasley will need to distinguish himself over a larger sample at Triple-A Charlotte before he gets a look with the White Sox.

MARCH 17, 2025 • ROTOWIRE

Gets NRI from ChiSox The White Sox signed Heasley to a minor-league contract Tuesday that includes an invitation to spring training.

Impact Heasley made four relief appearances with the Orioles in 2024, getting bludgeoned for 11 runs (10 earned) over 5.1 innings. Slated to turn 28 later this month, Heasley has posted a 5.89 ERA and 89:55 K:BB across 139 innings at the major-league level.

JANUARY 14, 2025 • ROTOWIRE

Let go by O's The Orioles released Heasley (shoulder) on Thursday, Jake Rill of MLB.com reports.

Impact Heasley was DFA'd on Wednesday to clear a spot on the 40-man roster for Chayce McDermott, and he'll now be sent into the open market after passing through waivers. The 27-year-old righty has been on the injured list at Triple-A Norfolk since June due to right shoulder inflammation, and the fact the Orioles had recently moved him to the 60-day IL suggests he won't be able to pitch until at least mid-August.

JULY 25, 2024 • ROTOWIRE

Removed from 40-man roster The Orioles designated Heasley for assignment Wednesday.

Impact The club needed a 40-man roster freed for Thursday's starter, Chayce McDermott. Heasley has been sidelined for more than a month at Triple-A Norfolk with a shoulder issue and it's not clear what his current health situation is.

JULY 24, 2024 • ROTOWIRE

Joins big-league bullpen The Orioles recalled Heasley from Triple-A Norfolk on Thursday, Dan Connolly of The Athletic reports.

Impact Heasley has been torched for seven runs (six earned) over 4.1 innings during his time with the Orioles this season. He's been much better at Norfolk, though, yielding just one run with an 18:4 K:BB in 20 frames. The right-hander should operate in middle relief.

MAY 23, 2024 • ROTOWIRE

Sent to minors The Orioles optioned Heasley to minor-league camp Sunday, Andy Kostka of TheBaltimoreBanner.com reports.

Impact The right-hander had a 3.52 ERA and 4:2 K:BB over 7.2 innings during spring training but won't be included on Baltimore's Opening Day roster. Heasley was acquired from the Royals in December and had a 7.20 ERA across 15 frames for Kansas City last season.

MARCH 24, 2024 • ROTOWIRE

Rough start to spring Heasley has allowed two runs on four hits and a walk with one strikeout over three Grapefruit League innings.

Impact Heasley's given up one home run. The 27-year-old right-hander was acquired by the Orioles in a trade from the Royals in December. Assuming the Orioles carry just one multi-inning option in the bullpen to begin 2024, Heasley appears to be behind Keegan Akin for that role, though both players figure to be part of the organization's plans this season.

Orioles acquire RHP Jonathan Heasley from Kansas City for minor league RHP Cesar Espinal

The Baltimore Orioles have acquired right-hander Jonathan Heasley from the Kansas City Royals for minor league righty Cesar Espinal

DECEMBER 19, 2023 • Associated Press

Traded to Baltimore The Orioles acquired Heasley from the Royals on Monday in exchange for Cesar Espinal, Jeff Passan of ESPN.com reports.

Impact Heasley was moved to the bullpen full-time in June last season and flashed some promise, but the results ultimately weren't there, as he held a 7.20 ERA and 9:2 K:BB over 15 innings during his time with the big club. The Orioles obviously see some potential with the righty and will try to coax more out of him.

DECEMBER 18, 2023 • ROTOWIRE

Optioned to Triple-A Heasley was optioned to Triple-A Omaha on Saturday.

Impact Heasley had been in the majors since early July. In his first seven appearances of his latest big-league stint, he allowed just one earned run in seven innings, but he's given up nine earned runs (including five homers) in 5.1 innings across his last four outings. He'll sort things out in the minors, with Max Castillo taking his place in the bullpen.

AUGUST 12, 2023 • ROTOWIRE

Summoned to majors Heasley was recalled from Triple-A Omaha on Tuesday.

Impact Heasley struggled in his lone appearance with the Royals this season and also holds a 7.51 ERA this year at Omaha. He'll provide the bullpen with some length.

JULY 4, 2023 • ROTOWIRE

Headed back to minors The Royals optioned Heasley to Triple-A Omaha on Sunday.

Impact Heasley tossed 2.2 innings and 38 pitches out of the bullpen in Friday's 12-8 loss to Oakland and wasn't likely to be available for another day or two, so the Royals are opting to move him off the 26-man active roster in favor of a fresh arm in Max Castillo, who was called up from Triple-A in a corresponding move. The 25-year-old Heasley should reclaim a rotation spot as he heads back to Omaha.

MAY 7, 2023 • ROTOWIRE

Promoted to big leagues The Royals recalled Heasley from Triple-A Omaha on Friday.

Impact Heasley hasn't gotten off to a great start in Triple-A this season, posting a 9.00 ERA and 1.65 WHIP through 31 innings over six starts. It's unclear whether the Royals will decide to use him in their starting rotation or as a multi-inning reliever, but he's not a recommended fantasy option either way. Austin Cox was optioned to Omaha in a corresponding move.

MAY 5, 2023 • ROTOWIRE

Optioned to Triple-A Heasley was optioned to Triple-A Omaha by the Royals on Friday.

Impact Heasley struggled in the majors last season to the tune of a 5.28 ERA and 1.49 WHIP across 104 frames, and his troubles have seemingly carried over into the spring (11.57 ERA, 2.29 WHIP through seven innings). He will likely need to show significant signs of improvement with Omaha before the Royals can feel comfortable bringing him back on the major-league roster.

MARCH 17, 2023 • ROTOWIRE

Not making strong case yet Heasley has allowed seven earned runs across four innings through two Cactus League appearances.

Impact Heasley isn't exactly making a great case to be in the Royals' rotation to begin 2023. He struggled last year as well, logging a 5.28 ERA, 1.49 WHIP and 70:47 K:BB across 104 innings over 21 starts. Without significant improvement in spring games, he could be sent to Triple-A Omaha or work out of the Royals' bullpen to start the campaign.

MARCH 5, 2023 • ROTOWIRE

Rocky start to end season Heasley (4-10) took the loss Wednesday, allowing six runs on nine hits and two walks over five innings against the Guardians. He struck out four.

Impact The Guardians got to Heasley early, tagging him for four runs in the first inning and one run in both the second and third innings. The start comes after he allowed four earned runs over 4.2 innings in his prior start and seven runs three appearances before that. Over 104 innings on the campaign, Heasley earned a 5.28 ERA and 1.49 WHIP with 70 punchouts.

OCTOBER 6, 2022 • ROTOWIRE

Takes ninth loss Heasley (4-9) allowed five runs (four earned) on six hits and one walk while striking out one across 4.2 innings to take the loss Thursday against Detroit.

Impact Heasley was hit hard throughout his start, as he allowed five extra-base hits -- including two homers. He entered the game having tallied a quality start in three of his last four appearances, though he also allowed seven earned runs in the other start during that span. Heasley should take one more turn through the rotation this season, and he'll enter that contest with a 5.00 ERA and 66:45 K:BB across 99 innings.

SEPTEMBER 30, 2022 • ROTOWIRE

Earns fourth win Heasley (4-8) allowed one earned run on two hits and two walks while striking out three across six innings to earn the win Thursday against the Twins.

Impact Heasley got 11 flyball outs and successfully kept the ball in the yard to turn in his second consecutive quality start. Since being recalled from Triple-A Omaha on Aug. 9, Heasley has maintained an impressive 3.26 ERA. However, that has come with just a 24:16 K:BB across 38.2 frames. Despite the strong results of late, Heasley owns only a 4.87 ERA across 94.1 innings for the season.
