The Royals selected Bummer's contract from Triple-A Omaha on Sunday.

The left-hander joined Kansas City on a minor-league deal July 20 and will get a look in the majors after delivering four scoreless outings for Omaha. Bummer made 19 appearances for Atlanta earlier this year and surrendered 13 earned runs with a 13:10 K:BB over 15.1 innings.

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.

The White Sox recalled Davitt from Triple-A Charlotte on Sunday.

The right-hander was up for his first taste of the majors in April and was sent back to Charlotte after firing a scoreless frame in his big-league debut. Davitt will now get another look in the majors despite having a 6.22 ERA, 1.49 WHIP and 64:25 K:BB across 59.1 Triple-A innings It'll likely be a short stay on the 26-man active roster since trade-acquisition Luis Castillo should officially join the team soon.

The Guardians optioned Dion to Triple-A Columbus on Sunday.

The left-hander spent most of June and July in the big leagues but has been shuttled between Triple-A and the majors a few times since the All-Star break. In his first taste of MLB this season, Dion has a 4.58 ERA, 1.37 WHIP and 25:3 K:BB across 19.2 innings. Trade acquisition Craig Yoho will fill the vacated roster spot for Cleveland.

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.

Perkins (2-7) allowed six runs on nine hits and a walk while striking out nine over 5.1 innings to take the loss Saturday versus the Tigers.

Perkins gave up five of those runs on homers, making this the third time in five outings he's yielded multiple long balls. In that span, he's been on the hook for 21 runs over 22.2 innings, though he also has a 27:11 K:BB in that span. On the year, Perkins is sporting an ugly 6.72 ERA, 1.40 WHIP and 89:28 K:BB over 73.2 innings across 27 games (nine starts), including a 7.38 ERA over 42.2 innings as a starter. Despite the ongoing struggles, he's penciled in to make his next start in Boston.

Jansen allowed one run on two hits and struck out two over one inning to earn the save in Saturday's 8-6 win over the Athletics.

Jansen posted an 8.1-inning scoreless streak in July, but it came to an end in his first appearance of August. He had a three-run cushion when he entered the game and was able to hold on for his 13th save of the campaign. The veteran closer has a 3.94 ERA, 1.25 WHIP and 34:18 K:BB through 29.2 innings while converting 13 of 17 save chances.
