Neither the Yankees nor the Astros will be playing baseball in October, but Friday will be the start of a special weekend at Minute Maid Park just the same.
Andy Pettitte, the Yankees' 41-year-old left-hander, will return to his hometown. The veteran was originally scheduled to take the mound on Friday, but his start was pushed back to Saturday. Adam Warren will go instead for the Yankees.
The Astros will be going with rookie left-hander Brett Oberholtzer in his final start of 2013. Against the Indians on Friday, he allowed two runs (none earned) on four hits in six innings for a loss.
"If we made a couple of defensive plays, we arguably could be standing here with a 1-0 victory," Astros manager Bo Porter said after the game. "He pitched that well. He continues to grind and make pitches and give us big performances."
Oberholtzer's 2.14 ERA over nine starts is the best mark among left-handers in the American League.
This weekend's series is also the final chance Houston fans will have to see Yankees closer Mariano Rivera pitch.
"I've been with Mo since '96. Had a lot of great times. He made my job fun, he made my job easy," Yankees manager Joe Girardi said. "But probably more important than that, he made all our lives better. And we'll miss him."
As all opposing clubs have done, the Astros will hold an on-field ceremony for Rivera on Saturday featuring Joe Torre and Roger Clemens.
Yankees: Rivera could play outfield
Girardi said on Thursday that he is "absolutely" considering having Rivera make an appearance in the outfield this weekend.
Although Rivera has often mentioned his hope of playing an inning in center field someday, Girardi said it would have to be under the right circumstances.
"You know, I don't know how I would do it," Girardi said. "It's something I would have to talk to him about. In my mind, thinking that he's going to want to pitch, it's a situation where I might bring him in in the eighth to play the outfield and then have him close it out in the ninth if we have that opportunity."
Astros: Youth movement on the mound
The Astros are in a season-long 12-game losing streak and have set a franchise record for losses, but their young starters have been impressive lately.
Houston's four rookie hurlers -- Oberholtzer, Jarred Cosart, Brad Peacock and Paul Clemens -- have combined for a 2.74 ERA in their collective 32 starts since July 12.
• The Yankees are 30-23 against left-handed starters this season.
• Astros second baseman Jose Altuve has four three-hit games in September.
