He went 3-for-4 and scored the winning run in the ninth inning Friday in a 1-0 victory over the Braves at Citizens Bank Park. He is hitting .345 (19-for-55) with one double, one triple, one home run, eight RBIs and an .855 OPS through 16 games.
His prowess at the plate is surprising, considering he entered the season with a .621 OPS in 500 big-league plate appearances and a .625 OPS in 2,631 plate appearances in the Minor Leagues.
"I feel really good right now," Galvis said. "I think Spring Training helped me a lot. I've been working a lot on it."
Galvis also helped turn three double plays to kill Atlanta's scoring opportunities. It included a big one in the fifth when the Braves had runners at the corners and one out.
"Right now we're not scoring too many runs," Galvis said. "We have to play defense if we want to win games."
Galvis singled to center field to get things going in the ninth. Pinch-hitter Cesar Hernandez executed a successful sacrifice bunt -- the team's third of the night -- to move Galvis into scoring position.
Galvis then advanced to third on a passed ball by Braves catcher A.J. Pierzynski.
"Real alert play," Phillies manager Ryne Sandberg said. "Real instinctive play getting over to third base."
"I was just trying to be ready," Galvis said. "Get to third on a base hit or something like that. And then I suddenly saw the ball on the ground, and with a big lead I just went for it."
Phillies center fielder Ben Revere then hit a ground ball to Braves first baseman Freddie Freeman, who charged the ball knowing that Galvis was running on contact. But Freeman did not field the ball cleanly and Galvis scored without a play at the plate.
"I tried to just get one up in the air, but with [Braves pitcher Jim Johnson] it's so tough," Revere said. "You know you've got Freddie right there, so I didn't want to hit a popup in the infield.
"So I was like, all right, if I could find a way to hit a little dribbler somewhere and get something. Of course he's going on contact, but luckily that was a little soft so Freeman had to try to come in and make a play and messed it up. So it worked for the best."
