Rollins scratched with right calf strain

Jimmy Rollins was introduced as the leadoff hitter and starting shortstop in pregame ceremonies but did not take the field with the rest of the team when the game against the Washington Nationals began.

Phillies officials say Rollins strained his right calf during pregame warmups.

Juan Castro started at short, making his first appearance in the 2010 season. He grounded out to third in the first inning as the leadoff batter.

The Phillies introduced their lineup in reverse order so Rollins could go last. He received the loudest of cheers. That was 15 minutes before the game began. Then, Rollins began warming up in the outfield with the rest of the team and suffered the injury.

UPDATE (5:21 p.m.): Another Phillies injury: Right fielder Jayson Werth left the game after the fifth inning with a sore left hip. He was replaced in right by Ben Francisco.

We'll have more on both Rollins and Werth after the game.
