Peterson did not factor into the decision in Saturday's 11-8 loss to the Marlins, allowing eight runs on eight hits and three walks with one strikeout over two-plus innings.

Peterson was tagged for five runs in the first inning and three more without recording an out in the third, finishing with just 36 strikes on 65 pitches. It marked the southpaw's shortest and roughest outing of the season, and he's now allowed at least four earned runs in three of his past five starts. For the year, he carries a 3.61 ERA, 1.31 WHIP and 136:58 K:BB across 152 innings and will try to rebound in a road matchup with the Reds next weekend.

May (7-11) took the loss Saturday, coughing up seven runs (six earned) on eight hits and four walks over 5.1 innings as the Red Sox fell 10-3 to the Pirates. He struck out five.

Boston held an early 2-1 lead as May gave up only an unearned run through four innings, but the wheels began to come off for the right-hander in the fifth after a leadoff single by Isiah Kiner-Falefa. May has been tagged for at least four runs in four of his last eight starts, stumbling to a 6.13 ERA, 1.64 WHIP and 38:18 K:BB over 39.2 innings during that stretch. He'll look to bounce back in his next outing, which is scheduled to come on the road next weekend in Arizona.

Oviedo (2-0) picked up the win in Saturday's 10-3 victory over the Red Sox, giving up two runs on three hits and three walks over five innings. He struck out six.

The right-hander was lifted after 79 pitches (48 strikes), sticking around just long enough for the Pirates' offense to erase an early 2-1 deficit, and then some. Oviedo has looked good in three starts since rejoining the rotation, posting a 2.57 ERA, 0.93 WHIP and 17:5 K:BB over 14 innings. He'll look to stay sharp in his next trip to the mound, which lines up to come at home next weekend against the Brewers.

Irvin (8-10) took the loss Saturday as the Nationals fell 4-1 to the Rays, giving up four runs on five hits and a walk over six innings. He struck out three.

The right-hander handled most of Tampa Bay's lineup without issue, but Josh Lowe launched homers off Irvin in the first and fourth innings to account for all the damage off him. Irvin will be happy to put August behind him -- over six starts he went 0-5 with an 8.78 ERA, 1.95 WHIP, 16:12 K:BB and 2.6 HR/9 in 27.2 innings. He'll try to turn things around in his next outing, which is scheduled to come on the road next weekend against the Cubs.

Pepiot (10-10) picked up the win Saturday, allowing one hit and three walks over five scoreless innings in a 4-1 victory over the Nationals. He struck out six.

The Rays staked Pepiot to a 3-0 lead in the first inning and he never looked back, racking up 15 swinging strikes among his 93 pitches (53 total strikes). The right-hander has won four of his last five starts, lasting at least five innings in each and posting a 3.25 ERA, 1.01 WHIP and 27:10 K:BB over 27.2 innings. Pepiot lines up to make his next outing at home next week against the Guardians.

Gausman didn't factor into the decision in Saturday's 4-1 loss to the Brewers, allowing one run on four hits over seven innings. He struck out eight without walking a batter.

The veteran righty rose to the challenge of facing the team with the best record in the league, firing 66 strikes among his 96 pitches in his 13th quality start of the season, but the Blue Jays couldn't give him much run support in a game that got decided in the ninth inning. Over eight outings since the All-Star break, Gausman has produced a 2.82 ERA, 0.82 WHIP and 53:9 K:BB in 51 innings. He'll look to keep rolling in his next trip to the mound, which is scheduled to come on the road next weekend in Yankee Stadium.

Priester came away with a no-decision in Saturday's 4-1 win over the Blue Jays, allowing one unearned run on five hits over six innings. He struck out three without walking a batter.

The right-hander was locked in a pitchers' duel with Kevin Gausman for six frames, with Priester exiting the mound after 82 pitches (56 strikes). The quality start was his fourth in eight starts since the All-Star break, a stretch in which he's gone 4-0 with a 2.76 ERA, 1.23 WHIP and 37:13 K:BB over 45.2 innings. Priester hasn't taken a loss since May 13, a streak he'll look to extend in his next outing, which lines up to come on the road next weekend in Pittsburgh.

The Padres are expected to recall Hart from Triple-A El Paso to pitch in Sunday's game against the Twins, Kevin Acee of The San Diego Union-Tribune reports.

The team hasn't yet announced whether Hart will start Sunday's contest or work as a bulk reliever, but he is penciled in to face Minnesota either way. The 32-year-old lefty carries a 5.29 ERA and 1.21 WHIP through 32.1 innings in the big leagues this year, but he's given up just two earned runs in 13.1 frames since being sent down to Triple-A in late July.

Manager Brian Snitker said Saturday that Quantrill will work as a long reliever going forward, Mark Bowman of MLB.com reports.

Chris Sale's return from the injured list left Quantrill as the odd man out of Atlanta's rotation, but the 30-year-old righty will remain with the big club as a multi-inning relief option. He's given up 12 earned runs in only eight innings since joining Atlanta, however, so he'll most likely be reserved for low-leverage situations.

Red Sox manager Alex Cora said Saturday that he's unsure if Tolle will start on four days' rest Wednesday versus Cleveland, Tim Healey of The Boston Globe reports

Tolle shined in his MLB debut Friday, allowing two runs on three hits with two walks and eight strikeouts over 5.1 innings in a no-decision against Pittsburgh. While the rookie southpaw should get another turn in the rotation, Healey notes that Tolle wasn't regularly pitching on four days of rest in the minors, so the Red Sox -- who will have an off day Thursday -- may opt to hold him back until next Friday's game in Arizona. That decision isn't set in stone yet, as Cora said the team is still thinking about who will start Wednesday.
