Joe Musgrove (8-12) gave up six runs and seven hits in five innings as Pittsburgh lost for the 29th time in 37 games since the All-Star break.

Eaton opened the scoring in the third with an RBI double and Anthony Rendon followed with a two-run single, giving him 100 RBIs. Following a walk to Juan Soto, Cabrera hit a drive to straightaway center field to make it 6-0.

It was Cabrera's second home run since being claimed Aug. 6 off waivers from the Texas Rangers and 14th overall. He was filling in at second base for Brian Dozier, who is on paternity leave.
