Roy Halladay tossed a complete game as the Philadelphia Phillies edged the Washington Nationals on Wednesday, while Detroit won again.
Halladay blanked the Nationals with eight shutout innings, allowing only a pair of singles to Adam LaRoche, before nearly handing the game away in the ninth as his pitch count ticked past 120.
The right-hander gave up a lead-off double to Rick Ankiel, a single to Jayson Werth and a one-out RBI to Laynce Nix to draw Washington within 3-1.
Danny Espinosa singled to shortstop to drive Werth home and suddenly the Nats were within a run with two outs still in hand.
But Halladay was up to the challenge, fanning pinch-hitter Matt Stairs and Ivan Rodriguez for the team's second win of the season.
Ben Francisco and Placido Polanco had RBI singles for the Phillies, and Halladay scored a free run after Ryan Howard was hit by a wild pitch from John Lannan with bases loaded in the fifth.
Elsewhere, the Detroit Tigers had their second straight walk-off win against the Texas Rangers thanks to Brandon Inge's solo home run.
Inge smacked closer Darren Oliver over the left-field wall with one out in the ninth, defeating the Rangers 5-4 and securing Detroit's first series win of the season.
The Tigers went behind 2-0 on RBI singles to Nelson Cruz and David Murphy in the sixth, but Brennan Boesch and Inge drove in runs at the bottom of the inning to keep the game tied up.
