OAKLAND, Calif. -- Matt Harrison knows a thing or two about starting big games. He was on the mound for Game 7 of the World Series and while that start didn't go the way he wanted, he's learned from the experience.

It's something he can draw Tuesday, when he takes the mound hoping to help lead the Rangers to a third consecutive AL West crown.

"It's unfortunate that we didn't do it (Monday), but I've been preparing myself to start no matter what," Harrison said. "I'm looking forward to it. It's a chance to clinch the division and I want to be on the mound."

Harrison said he feels good about what he's done in his last few starts. His last one came against the A's last week. He felt he didn't execute his pitches the way he wanted against Oakland last week, allowing four runs on seven hits in six innings despite getting the win.

Harrison is trying to become the sixth 19-game winner in Rangers history and the first since Rick Helling and Aaron Sele did it in 1998 (Helling won 20 games). He's been the club's most consistent pitcher all season and hasn't allowed rough innings or bad starts get him down. Texas needs him to be a stopper tonight as the club has lost five of its last seven.
