"He got off to a slow start with the bat coming out of Spring Training with his injuries, and the last time we saw him, his timing was way off and he was struggling, so a number of at-bats at Triple-A, which he's got under his belt now, has worked a long way with him and he's been swinging the bat pretty well," Phillies manager Ryne Sandberg said.
At Lehigh Valley, Galvis went 36-for-135 (.267) with three homers and 15 RBIs.
"That was important for him to have a number of at-bats, and he's played well on defense," Sandberg said. "He can be a little more versatile, being a right-handed bat, his versatility on defense.
"The task will also be getting him in there with some playing time and get some veteran guys some days off down the stretch -- that will be key for his playing time."
Brignac, meanwhile, delivered two walk-off hits for the Phillies, but hit .222 in 91 at-bats this season.
"Reid Brignac did a good job while he was with us," Sandberg said. "He helped us win some games when he played third base and Cody [Asche] was out and he had a chance to play. It was a little bit difficult with him with all our infielders being left-handed hitters. It's tough to get him some spots, where Freddy will create a little more versatility."
