The White Sox placed Leone on the 15-day injured list Monday with lower-back tightness.

EDGE Analysis

Leone tweaked his back during an appearance Saturday in St. Louis and now will be on the shelf for at least the next couple weeks. The veteran reliever holds a 6.75 ERA and 14:11 K:BB over 14.2 relief innings with the White Sox this season.

Leone was removed from Saturday's game against the Cardinals due to lower-back tightness, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

Leone entered the game in the eighth inning and was only able to get through one batter -- a five-pitch walk to Nolan Arenado -- before coming out of the game. The team officially labeled Leone as day-to-day, so his injury doesn't seem to be too severe, but the 32-year-old righty may take a few days off before pitching again.

Leone won't start Wednesday against Atlanta after the game was postponed due to inclement weather in Chicago.

EDGE Analysis

Leone had been scheduled to open Wednesday's game on the mound in what was set to be a bullpen day for Chicago, but as a result of the postponement, the game will be made up June 27. The White Sox will return to action Thursday in Kansas City, with Michael Soroka scheduled to start that contest and Leone set to return to his familiar bullpen role.

Leone will serve as the White Sox's opening pitcher for Wednesday's game versus Atlanta, Vinnie Duber of AllCHGO.com reports.

EDGE Analysis

The White Sox didn't name a No. 5 starter heading into Opening Day, but that void has since been filled by Mike Clevinger, who signed a one-year, $3 million deal with the club Monday. However, because Clevinger didn't participate in spring training and will require a ramp-up period before he's ready to make his season debut, the White Sox will opt for a bullpen day Wednesday in what would have been his first turn through the rotation. Expect Leone to work no more than one or two innings before giving way to a parade of relievers, with Tanner Banks being the most likely candidate to operate as a primary pitcher out of the bullpen if the White Sox elect to go that route.

The White Sox selected Leone's contract from Triple-A Charlotte on Wednesday, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

Leone was in camp as a non-roster invitee but made the team after giving up just two earned runs over eight innings this spring. The veteran reliever could even find himself in high-leverage spots as part of a bullpen that lacks clarity.

Leone signed a minor-league contract with White Sox on Tuesday which includes an invitation to major-league spring training, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

The veteran right-hander made 51 appearances between the Mariners, Angels and Mets last season but scuffled to a 4.67 ERA, 1.43 WHIP and 54:28 K:BB over 54 innings. Leone posted a 1.51 ERA with three saves and 15 holds in 57 outings for the Giants in 2021, but his 1.51 WHIP across the past two seasons is likely to be more indicative of his 2024 performance, if he makes Chicago's roster.

Leone was claimed off waivers by the Mariners on Thursday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Leone holds a 4.74 ERA and 44:20 K:BB across 43.2 innings of relief work for the Mets and Angels this season. It's a homecoming of sorts for Leone, who came up in the Mariners system and debuted for them back in 2014. He will be used in middle relief for the American League West leaders.

The Angels placed Leone on waivers Tuesday, Bob Nightengale of USA Today reports.

EDGE Analysis

Leone put up a 5.25 ERA and 1.83 WHIP across 12 innings since being acquired from the Mets at the trade deadline, and he'll now join five other Angels on the waiver wire as the team attempts to cut salary. Any team in search of bullpen depth will be able to simply claim the 31-year-old righty off waivers and add him to their active roster.

Leone picked up the save Tuesday against the Giants. He allowed one run on one hit while striking out one over two innings.

EDGE Analysis

Leone was picked up by the Halos at the beginning of August via trade and converted on his first save opportunity of the season. While he's expected to remain a middle reliever moving forward, Leone owns a 1.80 ERA and a 19:6 K:BB over his last 15 appearances (15 innings), and he could be a name to monitor for high-leverage work if Carlos Estevez's struggles persist.

The Mets traded Leone to the Angels on Tuesday in exchange for infielder Jeremiah Jackson, Joel Sherman of the New York Post reports.

EDGE Analysis

Leone's overall numbers don't look great, but he's pitched to a 1.80 ERA over his last 12 appearances dating back to late June. The 31-year-old right-hander will likely slide into a middle-relief role with the playoff-hopeful Halos.
