MILWAUKEE (AP) — Orlando Arcia’s pinch-hit single with two outs in the eighth inning drove in the tiebreaking run as the Milwaukee Brewers slipped past the Pittsburgh Pirates 6-5 on Monday night.

Ben Gamel led off the eighth with a double against Nick Turley (0-1) and scored on Arcia’s hit off Chris Stratton as the Brewers took three of four in the series.

Josh Hader pitched a perfect ninth for his eighth save in his first appearance since walking five of the six batters he faced while trying to close out Saturday night’s game. Hader has yet to give up a hit this season.

Devin Williams (3-1), the fourth of five Brewers pitchers, struck out four and didn’t allow a hit in 1 1/3 innings to pick up the win.

Keston Hiura homered for the Brewers, who also took advantage of shoddy fielding by the Pirates.

The Brewers got two runs in the second when Pittsburgh second baseman Kevin Newman bobbled Eric Sogard’s grounder with the bases loaded. Sogard was awarded a hit and an RBI, with the second run crossing on Newman’s throwing error to first.

Pittsburgh tied it in the third on Erik Gonzalez’s two-out, two-run homer off Brent Suter, who retired eight straight to start the game before walking Cole Tucker.

The Brewers took advantage of another error by Newman in the fourth that allowed struggling Omar Narvaez to score after his leadoff double.

Milwaukee extended its lead to 5-3 in the fifth on Hiura’s leadoff homer that chased starter Trevor Williams. Hiura has four home runs in 10 games against the Pirates this season and 10 in 26 career games versus Pittsburgh.

Williams gave up seven hits and five runs (three earned) in four innings.

The Pirates tied it again in the sixth on Jose Osuna’s two-run single off reliever Freddy Peralta.

The Brewers traded reliever David Phelps to the Phillies for three lower-level prospects to be named later. Phelps, 33, was in his first season with Milwaukee after signing as a free agent on Jan. 30. He appeared in 12 games and had a 2.77 ERA in 13 innings. “It became very clear early on that David was an attractive player to a number of teams,” Brewers general manager David Stearns said.

Up next, Josh Lindblom (1-2, 6.31) gets the start in the opener of a two-game interleague series against the Tigers at Miller Park. Michael Fullmer (0-0, 8.79) goes for Detroit.

Mike Clevinger, Starling Marte and Archie Bradley are among the notable players headed to new teams after a flurry of deals before Monday’s trade deadline.

The busy and aggressive Padres landed Clevinger in a multiplayer swap with Cleveland, bolstering their rotation in a rare deadline deal between contenders. It was San Diego’s fifth big trade since Saturday, and the cost was a package of young players that included outfielder Josh Naylor, right-hander Cal Quantrill and catcher Austin Hedges.

The surprising Marlins reeled in Marte for their outfield, and the Reds boosted their bullpen by acquiring Bradley from Arizona. The trade deadline is normally July 31, but it was pushed back when the start of the season was delayed.

“I’d say the volume of consummated transactions probably surprised me a little bit,” Brewers general manager David Stearns said.
