Leone (back) appears set to be activated from the 15-day injured list Monday, James Fegan of SoxMachine.com reports.

Leone has been on the shelf since May 6 with lower-back tightness, but he looks primed to be back in Chicago's bullpen after the minimum 15-day stay on the injured list. Right-hander Brad Keller was designated for assignment Sunday, opening a spot on the major-league roster for Leone once he's activated.

Stanek (2-0) got the win against the Orioles on Saturday, firing a scoreless two-thirds of an inning while recording a strikeout.

The hard-throwing reliever finished out the seventh inning after Gabe Speier had put two men on via a hit and a walk, retiring Adley Rutschman and Ryan O'Hearn via a strikeout and groundout, respectively, to preserve a 2-2 tie. Stanek eventually became the pitcher of record when the Mariners took a lead in the top of the eighth that held for the last two frames, giving him his second win of the campaign. The veteran right-hander pitched to an unsightly 9.00 ERA across the seven appearances he logged between April 25 and Monday, but he's now generated consecutive scoreless outings.

Manager Aaron Boone said Sunday that Kahnle (shoulder) will likely be activated from the 15-day injured list Wednesday, Gary Phillips of the New York Daily News reports.

After a rehab appearance Saturday, it appears Kahnle is moving in the right direction and could make his season debut this week. The 34-year-old finished out the 2023 season with a 2.66 ERA, along with a 48:19 K:BB and two saves across 40.2 innings.

Boushley was recalled Sunday from Triple-A St. Paul.

The right-hander will be sent up to the Twins while Jay Jackson was designated for assignment in a corresponding move. Boushley has recorded a 4.54 ERA and 1.14 WHIP with 38 strikeouts across 41.2 innings with Triple-A St. Paul and should fill a low-leverage role while up in the majors.

Jackson was designated for assignment by the Twins on Sunday.

The veteran reliever will be removed from the 40-man roster to free up space for right-hander Caleb Boushley, who was recalled by Minnesota in a corresponding move. Jackson will likely pitch for Minnesota's Triple-A affiliate in St. Paul if not picked up by another team.

Mata (hamstring) allowed two runs on four hits and one walk over two innings in a rehab start for High-A Greenville on Saturday.

Mata, whose rebab assignment moved from the Florida Complex League to Greenville, made his second rehab appearance. He worked a quick first inning but was knocked around in the second. "We just want him to throw strikes and hopefully the stuff is back," Boston manager Alex Cora told Julian McWilliams of The Boston Globe. "It's hard. So we'll see what happens in the upcoming weeks. Hopefully he stays healthy." Mata is out of options and will need to be activated to the parent club or get designated for assignment.

Slaten (2-2) was charged with Saturday's loss to the Cardinals. He allowed five runs (four earned) on five hits while striking out one over one inning.

Slaten handed back momentum a half inning after Boston tied the game, 2-2, in the top of the eighth. As sharp as Slaten was during April (0.52 ERA), he's been ineffective in May (10.80). The right-hander, who has two losses and a blown save in the last five appearances, has given up nine runs (eight earned) on 13 hits over 6.2 innings this month.

Rodriguez (1-0) picked up Saturday's win in extra innings over the Angels. He walked one and struck out one over two scoreless innings.

The Rangers received seven innings of one-run ball out of the bullpen, including the final two from Rodriguez. The right-hander has put together six scoreless frames over his last two outings.

There is no clear timeline for Poche (back) to be activated from the injured list, MLB.com reports.

Poche has received a pair of cortisone shots to relieve his pain and has been able to resume some baseball activity. However, his ramp-up has remained slow, making it unclear when he may be able to return.

Cano (2-2) allowed two runs on two hits in one-third of an inning to take the loss Saturday versus the Mariners.

Cano allowed the first two batters to reach base in the eighth inning, giving up one run in the process. Cionel Perez also allowed an inherited runner to score, and the Orioles couldn't overcome the deficit. This is the first time Cano has given up multiple earned runs in an appearance all season, and just the second time he's given up more than one run of any kind. He's now at a 2.95 ERA, 1.36 WHIP and 18:9 K:BB while adding two saves and 10 holds over 21.1 innings. The late-inning mix in Baltimore remains in flux, and Cano isn't doing himself any favors with three runs allowed over his last 1.1 innings across three appearances.
