CLEARWATER, Fla. -- Nobody knows where it will go once the regular season starts, but the Phillies are showing some pop in their bats this spring.
Cesar Hernandez hit a leadoff home run in the first inning in Sunday afternoon's 5-4 victory over the Astros in a Grapefruit League game at Bright House Field. It was Hernandez's first homer of the spring and the Phillies' 29th. They entered the afternoon with the second-most home runs of any team in Spring Training.

The Phillies scored twice in the fifth inning against Ken Giles, who is Houston's likely closer. It was the first time Giles faced the Phillies since they traded him in December.
Phillies right-hander Jeremy Hellickson, who is in line to start Opening Day, allowed no hits and three walks and struck out six in five scoreless innings. Astros left-hander Wandy Rodriguez, who is battling for a job on the team, allowed two hits and one run and struck out five in four innings.
