Lopez (groin) tossed a scoreless inning of relief to earn a hold in Saturday's 5-3 win over the Nationals. He allowed one walk and struck out one.

Lopez, who missed eight days due to a groin injury, looked good in his return to the mound. The righty has a stellar 2.34 ERA overall this season and has been even better since making his Chicago debut in late June. Across 23.2 innings with the Cubs, Lopez has turned in a 0.76 ERA and has struck out 26 batters. Porter Hodge earned the save Saturday and is likely first in line to close games moving forward, though Lopez figures to be in the mix as well now that he's healthy.

Thompson (7-4) was the losing pitcher in Saturday's game against the Dodgers, allowing two runs on three hits while striking out one over one inning.

Thompson entered with one out and a runner on and got the Diamondbacks out of the eighth inning unscathed, but trouble followed him in the ninth. He was removed after a pair of singles and a sacrifice bunt, then watched Justin Martinez let his two runners score. Thompson has largely been a dependable bullpen arm but is showing cracks this month. The submarining right-hander has a 6.17 ERA and a .327 batting-average against over 11.2 innings in August.

Phillips pitched a perfect inning to earn the save in Saturday's 8-6 win over the Diamondbacks.

Phillips was sharp in August, allowing two runs (one earned) over 12.1 innings while posting a 20:1 K:BB across 14 appearances. He picked up three saves, four holds, one blown save and one win, as the Dodgers have stuck with a committee approach to closing duties after Phillips' rough July. Overall, he has a 3.22 ERA, 1.12 WHIP and 55:12 K:BB with 18 saves in 21 chances and six holds over 44.2 innings this season.

Butto earned a save against the White Sox on Saturday, allowed one run on three hits in one inning.

The Mets held a three-run lead heading into the bottom of the ninth inning and turned to Butto to close things down. The right-hander didn't cruise, giving up a run on a trio of hits and allowing the tying run to reach first base, but he was ultimately successful in converting his third save of the campaign. Butto isn't a threat to Edwin Diaz's job as closer; Diaz was simply unavailable after pitching on three straight days.

Williams walked two and hit one batter in a scoreless and hitless inning, adding two strikeouts to earn the save in Saturday's 5-4 win over the Reds.

Williams has allowed multiple baserunners in three of his last five outings, but he was able to escape a bases-loaded jam of his own making in Saturday's win. The right-hander is now 8-for-9 in save chances this year. He's pitched to a 2.31 ERA, but a 1.20 WHIP and eight walks over 11.2 innings show he's not quite all the way back from a command standpoint. Williams has also logged 20 strikeouts and doesn't appear to be at much risk of ceding closing duties back to Trevor Megill.

Estevez allowed a hit and struck out two over a scoreless inning to earn the save in Saturday's 3-0 win over Atlanta.

Estevez didn't receive Philadelphia's last save chance, which went to Jeff Hoffman on Thursday. Hoffman handled the eighth inning Saturday against the top of Atlanta's lineup while Estevez worked through the heart of the lineup in the ninth. Estevez has allowed five runs (three earned) over 12.2 innings while earning three saves across 12 appearances since he was traded from the Angels. He now has a 2.31 ERA, 0.81 WHIP and 44:8 K:BB with 23 saves in 27 chances this year. Manager Rob Thomson looks to be sticking with a committee approach to closing, with Estevez, Hoffman and Jose Alvarado all in the mix for high-leverage spots.

The Phillies optioned Marte to Triple-A Lehigh Valley following Saturday's 3-0 win over Atlanta.

After being called up from Triple-A on Thursday, Marte made his lone appearance for the Phillies in Friday's 7-2 loss to Atlanta, covering two innings while allowing one run on two hits and one walk over two innings. He'll head back to Triple-A to make room for Jose Alvarado's (personal) return from the restricted list.

The Phillies activated Alvarado (personal) from the restricted list following Saturday's 3-0 win over Atlanta.

Alvarado has been away from the club since Monday due to a personal matter. The left-handed reliever will be available out of the bullpen for the series finale Sunday. Across 56 outings this season, Alvarado has recorded 13 saves and eight holds with a 4.30 ERA, 1.32 WHIP and 52:25 K:BB over 52.1 innings.

The Padres are expected to recall Cosgrove from Triple-A El Paso on Sunday, Kevin Acee of The San Diego Union-Tribune reports.

Cosgrove is expected to provide coverage for the Padres bullpen while Wandy Peralta (thigh) and Stephen Kolek (forearm) continue to work through their respective injuries. Cosgrove has an 11.66 ERA and 1.98 WHIP across 14.2 major-league innings this season.

Borucki (wrist) joined the Pirates in Cleveland on Saturday and could be activated from the 60-day injured list Sunday, Noah Hiles of the Pittsburgh Post-Gazette reports.

Borucki has been dealing with carpal tunnel syndrome in his left wrist since early April. He began his rehab assignment Aug. 17 and has given up a run while striking out eight in five innings across five appearances.
