Hart will start Sunday's game against the Giants.

Hart hasn't pitched since serving as an opener Wednesday versus Colorado, and he'll fill the role again for Sunday's series finale versus San Francisco. He covered a season-high 2.2 innings during that outing and has lasted as least two frames in 13 of his 28 appearances, so a similar workload seems likely this time around. Michael King's start was pushed to Monday after he was previously penciled in to pitch Sunday.

The Pirates optioned Mattson to Triple-A Indianapolis on Sunday.

The right-hander was just called up Saturday and will return to Indianapolis without making an appearance. Mattson has been inconsistent across 36 big-league outings this year with a 4.93 ERA, 1.56 WHIP and 33:16 K:BB over 34.2 innings.

Atlanta placed Lopez (knee) on the 15-day injured list Sunday.

Atlanta is labeling Lopez's injury as left knee inflammation, though Mark Bowman of MLB.com relays that the club is still awaiting the results of the right-hander's MRI before providing a timeline for his return. Right-hander JR Ritchie was recalled from Triple-A Gwinnett in a corresponding move and will step in as Atlanta's new fifth starter beginning with Sunday's game against the Nationals. Since moving back into the rotation in late June after a two-month stint in the bullpen, Lopez went 1-2 with a 3.86 ERA, 1.29 WHIP and 27:8 K:BB in 28 innings over six starts.

Martinez (elbow) will begin a rehab assignment at Single-A Visalia on Tuesday, MLB.com reports.

Martinez participated in a camp game Friday and reportedly hit 100 mph on his four-seamer. The recent upheaval in the Diamondbacks' bullpen -- Paul Sewald was removed as closer -- indicates Martinez could reclaim the job once he's healthy. That may not happen until September, however.

Sewald allowed five runs on five hits and failed to retire a batter in Saturday's 12-8 win over the Guardians.

Sewald was making his first appearance since being dropped from the closer's role earlier in the week, and it didn't go well. It appeared that manager Torey Lovullo was giving the demoted closer an opportunity to build confidence -- Arizona was leading 10-2 when Sewald entered to begin the eighth inning -- but he allowed five straight hits and was on the hook for three runners on base when he was removed from the game.

Miller (4-1) blew a save but earned the win over the Giants on Saturday, allowing one hit and walking one batter while striking out three over 1.2 innings.

Miller was summoned with one out and the bases loaded in the eighth inning to try to protect a two-run lead. He struck out the first batter he faced but then gave up a two-run, game-tying double to Osleivis Basabe. Miller retired the final batter he faced in the frame and also pitched a scoreless ninth, and he emerged with the win after San Diego walked it off in the bottom of the frame. Though he wasn't charged with any runs, Miller was tagged with his first blown save of the campaign in his 29th opportunity. He nonetheless lowered his ERA to a sparkling 0.76 and now has a jaw-dropping 88:16 K:BB across 47.1 innings spanning 45 appearances.

Megill pitched a perfect inning with no strikeouts to earn the save in Saturday's 3-1 win over the Angels.

Megill has given up just three runs over 20.1 innings since the start of June. After some early struggles this season, the Brewers closer continues to get the job done -- he's now 18-for-20 in save chances while also adding seven holds. He's maintained a 2.83 ERA with a 0.94 WHIP and 50:11 K:BB through 41.1 innings this year.

Mikolas (3-8) took the loss against Atlanta on Saturday, allowing four runs on nine hits and one walk while striking out three batters over six innings.

Mikolas struggled to keep the ball in the park, at Atlanta teed off for three homers against him, including two in the first inning. The right-hander at least managed to give Washington six frames, but he ultimately fell to his eighth defeat of the campaign and his first since June 29. Mikolas' ERA now stands at 5.67 through 108 frames, which would be the worst mark in the league if he had enough innings to qualify (he's currently four frames short). He's lined up for a tough road matchup in Philadelphia his next time out.

Atlanta manager Walt Weiss said Saturday that Lopez (knee) will likely go on the 15-day injured list, Chad Bishop of The Atlanta Journal-Constitution reports.

Lopez was scratched from his scheduled start Saturday against the Nationals due to left knee inflammation. He'll undergo an MRI to determine the severity of the knee injury, but Atlanta is already anticipating Lopez to be down for at least the next two weeks. JR Ritchie is expected to be called up from Triple-A Gwinnett to start in Sunday's series finale and could make a few turns through the rotation while Lopez is shelved.

Soto secured the save Saturday against the Reds, throwing a clean ninth inning. He struck out one.

Soto made quick work of the Reds, firing nine of his 11 pitches for strikes. The Pirates acquired Camilo Doval from the Yankees on Saturday to bolster the back end of their bullpen, and 29-year-old possesses closing experience that offers Pittsburgh another option for high-leverage spots. Soto has been shaky as the club's primary closer this season, posting a 3.69 ERA, 1.06 WHIP and 53:20 K:BB with 14 saves in 19 attempts over 46.1 innings.
