Estevez earned the save against the Mets on Saturday, allowing one hit in a scoreless ninth inning.

Estevez was summoned to protect a 6-4 lead in the ninth and worked around a leadoff single to secure his sixth save with the Phillies. The 31-year-old has yielded just four earned runs in 17 appearances since being traded while continuing to see the bulk of ninth-inning opportunities. On the year, he is 26-for-31 in save chances with a 2.22 ERA, 0.82 WHIP and 48:9 K:BB across 52.2 innings.

The Giants optioned Warren to Triple-A Sacramento on Saturday, Alex Pavlovic of NBC Sports Bay Area reports.

Warren made three appearances with the Giants after being recalled from Triple-A on Sept. 6. Over that span, he allowed two runs on four hits and two walks while striking out two across 4.2 innings. The move makes room on San Francisco's 28-man roster for the reinstatement of Jordan Hicks (shoulder) from the 15-day injured list.

The Padres optioned Cosgrove to Triple-A El Paso on Saturday.

Cosgrove came up from the minors Wednesday as a roster replacement for Martin Perez (paternity), and he'll head back to Triple-A now that Perez has returned. The 28-year-old Cosgrove didn't appear in a game during his three-day stint in the big leagues.

The Diamondbacks selected Hughes' contract from Triple-A Reno on Saturday.

With Ryne Nelson (shoulder) headed for the injured list, Hughes will rejoin the active roster in order to give the Diamondbacks some additional depth in their bullpen. The 28-year-old lefty hasn't found much success in the big leagues with a 10.29 ERA across 14 innings, though he's turned in a 2.08 ERA and 1.20 WHIP across 21.2 frames at Triple-A since making his last MLB appearance. Andrew Knizner was DFA'd to create space for Hughes on the 40-man roster.

The Phillies optioned Lazar to Triple-A Lehigh Valley on Saturday.

After coming up from Triple-A in late August, Lazar surrendered seven earned runs over just eight innings. His poor performance will cause him to be sent back to the minors while Kolby Allard rejoins the big-league squad to start Saturday's game.

Bivens appeared out of the bullpen in Thursday's 3-0 loss to the Brewers, giving up two runs on two hits and no walks while striking out two in two innings.

Bivens returned to a relief role after he had made his previous appearance as a starter Sunday, when he tossed 4.2 innings of one-run ball while striking out three in the Giants' 7-6 win over the Padres. The Giants still have a pair of openings in the rotation with Kyle Harrison (shoulder) recently joining Robbie Ray (hamstring) on the injured list, but rookies Mason Black and Landen Roupp will fill those spots rather than Bivens.

Fernandez (1-5) allowed a run on two hits and a walk while striking out one over 1.1 innings Friday, taking the loss in extra innings versus the Blue Jays.

The walk Fernandez issued was intentional, but it ended up helping the Blue Jays load the bases with no outs in the 11th inning. Fernandez was able to get one out on a fielder's choice to erase the initial runner, but Alejandro Kirk then delivered a walk-off single. Prior to Friday, Fernandez was on a 6.1-inning scoreless streak. The rookie reliever has pitched to a 3.21 ERA despite a 1.30 WHIP and 63:31 K:BB over 61.2 innings, and he's added two saves and 11 holds.

Williams struck out one in a perfect inning to earn the save in Friday's 2-1 win over the Diamondbacks.

Williams collected his third save in four days by retiring the side on 14 pitches in the ninth inning. He's avoided a prolonged slump after a blown save Aug. 21 versus the Cardinals, following it up with a nine-inning scoreless streak that has seen him earn seven saves with a 16:4 K:BB. Williams is now at a 1.53 ERA, 1.02 WHIP and 32:9 K:BB with 12 saves in 13 chances over 17.2 innings this season.

Ortiz (6-6) took the loss Friday against the Royals, allowing seven runs (four earned) on five hits and two walks over four innings. He struck out five.

Ortiz and the Pirates fell into a deep hole early after Kansas City put up a six spot in the second inning. The 25-year-old Ortiz has now allowed 11 runs (seven earned) across 9.2 innings in his last two starts. His ERA sits at 3.45 on the year with a 1.13 WHIP and 95:39 K:BB across 122.2 innings. He'll look to right the ship in his next outing, currently scheduled for next week on the road in St. Louis.

Finnegan allowed a hit in a scoreless inning and earned a save over the Marlins on Friday.

Finnegan worked around a two-out single by Jesus Sanchez to finish off the 4-1 victory. It was Finnegan's 37th save of the year and his first since recording two during a Sept. 7 doubleheader against the Pirates. He owns a 3.36 ERA with a 56:20 K:BB through 59 innings. Finnegan has converted 14 of his last 15 save chances despite registering a 4.79 ERA during that span (21 appearances).
