Cantillo (4-3) earned the win over the Red Sox on Wednesday, allowing one run on five hits and two walks while striking out seven over six innings.

Cantillo was impressive against a tough Boston lineup, completing six innings for the first time this season. The southpaw's lone blemish came in the fourth inning when Boston scratched across a run on three singles, but he quickly rebounded to retire seven of the final eight batters he faced. Wednesday's performance continued a strong stretch in which Cantillo has now allowed exactly one run in three straight outings. Across his nine starts this year, the 25-year-old has posted a 3.68 ERA and 51:24 K:BB over 44 innings.

Ellard will serve as the White Sox's opening pitcher for Thursday's game against the Twins, Scott Merkin of MLB.com reports.

Ellard will work as an opener for the second time in four days after coughing up one unearned run in 1.2 innings in Monday's 6-5 win over Minnesota. Jonathan Cannon is expected to pitch in bulk relief after Ellard exits the game.

Topa (1-5) was charged with the loss and a blown save in a 4-3 defeat to the White Sox on Wednesday, allowing one run on two hits and no walks with one strikeout in two-thirds of an inning.

That's consecutive blown saves for Topa, who has now given up at least one run in four straight outings. Given the right-hander's recent struggles, it wouldn't be surprising to see manager Rocco Baldelli turn to a different high-leverage arm, such as Cole Sands or Kody Funderburk, for Minnesota's next save chance. Topa has a 4.03 ERA and 1.45 WHIP over 58 innings this season.

Leasure picked up the save in a 4-3 win over the Twins on Wednesday, allowing one hit and one walk with no strikeouts in a scoreless ninth inning.

Leasure turned in his sixth save of the season, and it was also his fourth consecutive scoreless outing. The right-hander had a 4.62 ERA for the year through July 28, but he's been exceptional out of the Chicago bullpen since the start of August. Over his last 14 innings, Leasure has a 2.57 ERA, 0.71 WHIP and 22:4 K:BB with four saves to enhance his ERA to 4.08 for the campaign.

Cano earned the save in Wednesday's 7-5 win over San Diego, striking out two in a perfect ninth inning.

Cano was sharp Wednesday, striking out a pair to lock down his second save this season, his first since July 5. The 31-year-old Cano has pitched better of late, allowing just one run in his last six appearances (5.2 innings) to reclaim a high-leverage role in Baltimore's bullpen. Overall, his ERA sits at 5.07 with a 1.45 WHIP and 47:22 K:BB across 49.2 innings this season.

The Astros transferred Rooney (elbow) to the 60-day injured list Wednesday, Matt Kawahara of the Houston Chronicle reports.

Elbow inflammation sent Rooney to the injured list last week, and moving to the 60-day IL will officially put an end to his regular season. The 28-year-old turned in a 2.56 ERA and 1.19 WHIP in 38.2 innings in Triple-A and gave up one run in 1.1 frames during his MLB debut. Jayden Murray was selected to the active roster in a corresponding move.

The Mariners recalled Kowar from Triple-A Tacoma and placed him on the 15-day injured list Wednesday with a right shoulder impingement, retroactive to Aug. 19.

Kowar was sent down to Triple-A in mid-August but hasn't pitched for Tacoma since being demoted. Now dealing with a shoulder issue, the 28-year-old will return to the big-league club to rehab his injury. He'll be eligible to return from the IL as soon as he's healthy, but there's currently no telling how close he is to activation.

The Guardians optioned Kent to Triple-A Columbus on Wednesday.

Kent is clearing out to make room on the roster for Joey Cantillo , who was recalled from Triple-A to start Wednesday's game in Boston. The righty has made nine relief appearances with the big club this season, allowing five runs with a 9:6 K:BB across 9.2 innings.

The Guardians recalled Cantillo from Triple-A Columbus ahead of his scheduled start Wednesday in Boston.

The left-hander has offered a mixed bag with the Guardians this season, posting a 3.93 ERA and 80:36 K:BB over 66.1 frames covering eight starts and 21 relief appearances. The Guardians haven't indicated whether Cantillo's appointment to the rotation will be a permanent one, as his performance against the Red Sox may play a big part in determining whether he makes additional starts, gets moved to the bullpen or optioned back to Triple-A.

The Angels optioned Silseth to Triple-A Salt Lake on Wednesday.

He's being sent out to make room on the active roster for Wednesday's starting pitcher, Caden Dana, who was recalled from Salt Lake. Silseth didn't allow a run over his three relief appearances for the Angels following his Aug. 24 call-up.
