If the Astros force a Game 5 in the World Series, Roger Clemens is expected to get the nod to start. On Monday, Astros manager Phil Garner said he planned to start Clemens if there was a Game 5 on Thursday night in Houston. The Houston ace was forced out of Game 1 after only two innings, walking gingerly because of a recurring strained left hamstring that has bothered him since September. The Astros lost the opener 5-3, and now trail 0-2 in the best-of-seven series after a dramatic 7-6 loss to the White Sox on Sunday. Garner said either Wandy Rodriguez, who worked 3 1/3 shaky innings in relief of Clemens in Game 1, or Ezequiel Astacio, who started 14 games for the Astros this season, would get the nod if Clemens wasn't healthy. But Garner seemed certain that Clemens would be ready. "Roger Clemens is pitching the fifth game right now," Garner said.
