The Pirates are expected to option Oviedo to Triple-A Indianapolis on Tuesday, Alex Stumpf of MLB.com reports.

Oviedo struggled in Monday's 5-4 win over the Giants in what was his first start in the majors since 2023, after he missed the entire 2024 campaign while recovering from Tommy John surgery and the first several months of this season while recovering from a lat strain. He yielding two runs on two hits and three walks while needing 43 pitches to cover his lone inning. With the bullpen now short after it had to cover eight innings Monday, the Pirates are replacing Oviedo with a fresh relief arm in Cam Sanders, who will be called up from Triple-A.

The Nationals will recall Cavalli from Triple-A Rochester to start Wednesday's game versus the Athletics, Grant Paulsen of 106.7 The Fan Washington reports.

Cavalli is set to make his first start in the big leagues since August 2022, after the right-hander encountered some setbacks following his March 2023 Tommy John surgery. The 26-year-old has collected a 9.00 ERA over his last six starts with Rochester, but a 31:9 K:BB over 27 frames during that time offers more promise. He should get an opportunity to hold down a rotation spot with the Nationals for the rest of the season.

Martinez allowed two earned runs on two hits and no walks in 2.1 innings of relief in Monday's 3-2 win over the Cubs.

After starting in each of his previous seven appearances, Martinez was moved to the bullpen to open up a spot in the rotation for Zack Littell, whom the Reds acquired from the Rays ahead of the trade deadline. Martinez's stay in the bullpen could be a brief one, as he was pressed into action in long relief after starter Nick Lodolo recorded just five outs before exiting with a left index finger blister. Reds manager Terry Francona said after the game that Lodolo is likely to go on the injured list, so Martinez represents a logical choice to replace the southpaw in the rotation the next time his turn comes up this weekend in Pittsburgh. Martinez may be needed for just one start, as Cincinnati could get ace Hunter Greene (groin) back from the IL as soon as next week.

Cortes (elbow) is scheduled to start Wednesday's game against the Diamondbacks at Chase Field.

San Diego reinstated Cortes from the 60-day injured list Sunday, but he'll end up waiting a few days before entering the rotation as a replacement for Randy Vasquez, who was optioned to Triple-A El Paso in a corresponding move. Acquired from the Brewers this past Thursday, Cortes made just two starts at the big-league level before landing on the IL on April 6 due to a left elbow strain. Before being traded, Cortes proved his health over the course of a four-start rehab assignment in July, during which he turned in a 1.00 ERA, 0.72 WHIP and 18:3 K:BB in 18 innings. After building up to 93 pitches in his final rehab outing July 24, Cortes isn't expected to face a workload restriction Wednesday in his Padres debut.

Reds manager Terry Francona said after Monday's 3-2 win over the Cubs that Lodolo (finger) is likely to be placed on the 15-day injured list, Casey Drottar of MLB.com reports.

Lodolo lasted only 1.2 innings Monday before exiting his start due to a blister on his left index finger. The southpaw has dealt with blister problems before, which factors into the Reds' decision to "err on the side of caution" with Lodolo, per Francona. Assuming Lodolo is indeed placed on the IL, he would be eligible to return Aug. 20. Nick Martinez worked 2.1 frames in relief of Lodolo and could slide back into the rotation in his place.

Glasnow allowed one run on three hits and two walks while striking out seven over seven innings in a no-decision Monday versus the Cardinals.

Glasnow bounced back after allowing four runs over four innings versus the Reds in his last start. The right-hander has allowed exactly one run in four of five outings since returning from a shoulder injury. Glasnow is now at a 3.06 ERA, 1.09 WHIP and 56:23 K:BB through 47 innings across 10 starts this season. He's projected to make his next start on the road versus the Angels next week as the Dodgers continue to work with a six-man rotation to ease the workload of multiple pitchers, including Glasnow, who have dealt with long-term injuries this year.

Gray allowed one run on one hit and one walk while striking out eight over seven innings in a no-decision versus the Dodgers on Monday.

Gray brought one of his best outings of the season, with only a Freddie Freeman solo shot in the fourth inning marring his line. This was a positive sign, as Gray allowed 26 runs (24 earned) over 27.2 innings across his six starts in July, including a pair of 11-hit outings, though his 32:3 K:BB last month suggests a bit of misfortune was in the mix. He's now at a 4.21 ERA, 1.17 WHIP and 141:21 K:BB through 128.1 innings across 23 starts this season. Gray's next start is expected to be another tough one this weekend at home versus the Cubs.

Gordon (2-4) allowed seven runs on 11 hits and no walks while striking out one batter over 2.2 innings to take the loss against Toronto on Monday.

Gordon struggled from the outset, giving up a run on three hits in the first inning. That frame was just the beginning of a rough outing for the right-hander; he gave up another run in the second and then had the bottom fall out in the third, when Toronto tagged him for six hits (three of which went for extra bases) while putting five more runs on his ledger. Gordon unsurprisingly didn't survive that inning, as he was pulled with two outs after 67 pitches. Gordon posted a respectable 3.13 ERA through his first four MLB appearances this season, but that number has ballooned to 6.59 following back-to back ugly starts during which he's surrendered a combined 14 runs (13 earned) across just 5.2 frames.

Pfaadt (11-7) allowed two runs on five hits and three walks while striking out four over 5.2 innings to earn the win over the Padres on Monday.

Pfaadt was effective at limiting the damage, bouncing back after giving up three home runs in a seven-run meltdown versus the Tigers in his last start. While he kept the ball in the yard this time, the three walks matched his season high, which he's now done three times. The right-hander has a 5.02 ERA, 1.31 WHIP and 102:28 K:BB through 122 innings over 23 starts this season. He's still prone to the occasional disaster outing, but he's been fairly steady since mid-June. Pfaadt's next start is projected to be at home versus the Rockies this weekend.

Sears (7-10) allowed five runs on 10 hits and one walk while striking out four over five innings to take the loss versus the Diamondbacks on Monday.

Sears' debut for the Padres wasn't pretty, as the Diamondbacks were able to plate at least one run in each of the first four innings. The southpaw has allowed 19 runs (17 earned) across his last five starts (23.1 innings). Overall, he has a 5.12 ERA, 1.31 WHIP and 101:30 K:BB through 116 innings across 23 starts between the Athletics and Padres. Sears' first home outing for the Padres is expected to be this weekend against the Red Sox.
