Olson is scheduled to throw a bullpen session Saturday, Evan Woodbery of MLive.com reports.

Olson threw off a mound Wednesday for the first time since being placed on the injured list July 21 due to a right shoulder strain. The 24-year-old is slated for another side session Saturday. He's still expected to be sidelined for multiple weeks, but he seems to be progressing well.

Warren will start Saturday's game against the Rockies at Yankee Stadium, Chris Kirschner of The Athletic reports.

Warren was called up from Triple-A Scranton/Wilkes-Barre on Wednesday to take Luis Gil's (back) spot on the active roster, and he'll now slot into Gil's spot in the rotation this weekend. In three big-league starts this season, Warren has an 8.59 ERA with a 17:5 K:BB, though those numbers are skewed heavily by an eight-run start against the Angels on Aug. 7.

The Angels selected Zeferjahn's contract from Triple-A Salt Lake on Friday.

Zeferjahn was part of the return package in the trade that sent Luis Garcia to Boston. After stumbling to a 5.47 ERA with a 31:17 K:BB across 24.2 innings with the Red Sox's Triple-A affiliate, Zeferjahn has tallied a 2.35 ERA and an 8:1 K:BB in 7.2 innings for Salt Lake. The 26-year-old will take Mike Baumann's spot on the 26-man and 40-man rosters.

The Red Sox transferring Paxton (calf) to the 60-day injured list Friday, Mac Cerullo of the Boston Herald reports.

The 35-year-old was placed on the 15-day IL on Aug. 12 due to a partially torn left calf, and he won't be eligible to return before the end of the regular season. The Red Sox are currently 3.5 games back of the final wild-card spot in the American League, but there's an outside chance Paxton will be available in mid-October should Boston make a playoff run.

The Rangers could call Leiter up from Triple-A Round Rock to start Wednesday's game against the White Sox, Evan Grant of The Dallas Morning News reports.

Leiter has been in the minors since mid-May after yielding 17 runs in 9.1 innings over his first three big-league starts. The No. 2 overall pick in the 2021 First-Year Player Draft has turned things around at Round Rock lately, posting a 2.57 ERA and a 63:18 K:BB across 42 innings during his last nine starts. With Max Scherzer (shoulder) suffering a setback that will prevent him from returning from the 15-day injured list next week and Dane Dunning experiencing diminished velocity in his most recent spot start, Leiter looks like he could be given the next chance to fill the fifth spot in the Texas rotation.

Burnes (12-6) took the loss against Houston on Thursday, allowing six runs (five earned) on eight hits and two walks while striking out two batters over 5.2 innings.

Burnes began his outing with three scoreless frames before the Astros tagged him for two runs in the fourth. Following a 1-2-3 fifth inning, the veteran righty folded in the sixth, giving up five hits -- all singles -- to allow four runners to score. In fact, all eight of the knocks Burnes allowed in the contest were singles, so he wasn't exactly hit hard, though the right-hander gave up too much contact with just six whiffs and two punchouts. He still has a respectable 3.28 ERA on the campaign, but over his past four starts he's uncharacteristically posted an 8.71 ERA over 20.2 frames.

Arrighetti (6-11) notched the victory against Baltimore on Thursday, allowing three hits and issuing one walk while striking out six batters over six scoreless innings.

Arrighetti began August with two excellent outings before stumbling with a 5.2-inning, four-run loss to the White Sox last Friday. The rookie bounced back with one of his best starts of the season Thursday, as he allowed just four total baserunners and retired the final eight batters he faced. Arrighetti also collected his fourth quality start over his past five outings, a span during which he has a 2.93 ERA and 44:8 K:BB across 30.2 frames.

Maeda (2-6) took the loss Thursday against the Cubs, allowing six runs on nine hits and two walks across five innings. He struck out five.

Maeda was hit early and often while serving in bulk relief Thursday, allowing a grand slam to Miguel Amaya in the second frame and surrendering a pair of doubles later in the outing. Since the start of July, Maeda has stumbled to a 7.60 ERA with a 31:8 K:BB across 36 innings. Though he may follow an opener again, Maeda is tentatively scheduled to pitch against the Angels early next week.

Canning pitched six scoreless innings, giving up two hits and no walks while striking out six batters, in bulk relief against Toronto on Thursday.

The Angels trailed 5-0 by the time Canning got the ball in the third inning, but the right-hander kept his club in the contest with six dominant scoreless frames. This was the first time Canning worked in any capacity other than a traditional starter this season, and he adapted well to the role in racking up 13 whiffs and throwing 54 of 74 pitches for strikes. It wouldn't be surprising if the Angels have Canning work behind an opener again in his next appearance given the results Thursday. He had been struggling with a 5.41 ERA and 1.42 WHIP across 133 frames prior to the superb outing against Toronto.

Springs (1-2) took the loss Thursday against Oakland, allowing three runs on seven hits and two walks across 3.1 innings. He struck out three.

After completing five innings in three straight starts, Springs failed to get through the fourth Thursday. While all three of his allowed runs came before the fourth frame, Springs was removed after 82 pitches following a Darell Hernaiz double. Since making his season debut in late July, Springs has a 4.50 ERA with four home runs allowed and a 24:7 K:BB over 22 innings. He's on track to face the Mariners early next week.
