Pedro Martinez will rejoin the New York Mets for a bullpen session today as he looks forward to returning from an ailing hamstring.

But he's not sure if he will pitch beyond 2008. After his latest rehab assignment in Port St. Lucie, Fla., Martinez told the New York Daily News he was might retire after this season to be with his ailing father.

Martinez' 78-year-old father, Pablo, has a form of brain cancer.

"It's taking a toll on me and my family, my dad's situation," Martinez was quoted as saying. "That'll probably drag me away from the game a little sooner than people expect. After this season, I'm going to go back home and think about it and I'm going to decide."

The 36-year-old righthander has been on the disabled list since April 2 with a hamstring injury.

Noteworthy

* The Houston Astros removed a yellow board on an outfield wall that contributed to a botched home run call Monday night.

The Cubs' Geovany Soto got an inside-the-park three-run homer in the fourth inning despite replays showing it should have been an automatic home run. The ball bounced just to the right of the yellow line on a board on the wall in left-centerfield. The Astros removed the board, which apparently wasn't tightly secured and moved in the breeze, and painted a yellow line on the wall itself.

* San Diego placed righthander Jake Peavy on the 15-day disabled list with a strained right elbow.

In games yesterday:

* At Atlanta, Tom Glavine (2-1) retired his last 17 hitters to lead the Braves to a 6-1 victory over the New York Mets in the opener of a day-night doubleheader, and Jorge Campillo (1-0) pitched six scoreless innings for his first major league win to lead Atlanta to a 6-2 win in Game 2.

Atlanta's Mark Kotsay hit a two-run homer in the nightcap. Brian McCann homered and drove in three runs for the Braves in Game 1.

In other Diamondbacks news, lefthander Doug Davis, who has been recovering from thyroid cancer surgery, will return to the rotation Friday at Atlanta. His thyroid gland was removed April 10.
