First Pitch: Last pitches for Pettitte?

Andy Pettitte has started 518 times in his major league career. In 435 of them, he has pulled his blue cap tight and started for the Yankees. He has 255 career wins, 218 of which have come in pinstripes.

He may be making the third to last start of his career on Tuesday night. After Tuesday, his next start will be Sunday at home against the San Francisco Giants, which, appropriately enough, is the day the Yankees will be honoring Mariano Rivera.

So it should be a celebratory day from start to finish at the Stadium because there will be a sense that this could be Pettitte's final home start of his career. The two have combined for the most win and save combinations in history with 74.

The Yankees playoff hopes are still alive, so Pettitte will try to do some work against the Blue Jays, whom historically he has been very good against.

Pettitte is 25-13 with a 3.94 ERA in 46 starts (47 games) against the Blue Jays. This season against Toronto, he is 3-0 with a 1.77 ERA.

Pettitte has been the Yankees' best starter down the stretch. In his last seven starts, he is 3-0 with a 2.12 ERA.

"The way he is pitching now, I think he could pitch another five years," Pettitte's agent Jim Murray told ESPNNewYork.com on Monday.

No one knows for certain what the 41-year-old Pettitte will decide. He has a little Brett Favre in him when it comes to the whole retirement thing. He publicly struggles with the pain of being away from his family during the long baseball season. He tried retirement once and then decided to come back. Murray said that there have been no decisions on Pettitte's future, and he expects Pettitte to make his final call in the offseason.

This could very well be it. Pettitte's final road start as Yankee -- and then his last one on Sunday, Mo's day.
