FOUNTAIN HILLS, Ariz. — The wife of Arizona Diamondbacks pitcher Scott Schoeneweis was found dead at her home yesterday.

Police said the cause of death hasn't been determined.

The Maricopa County Sheriff's Office said deputies found the body of 39-year-old Gabrielle Dawn Schoeneweis on the floor of the master bedroom in the family's suburban home shortly after noon.

Authorities said her 14-year-old daughter called the sheriff's office to report that she had found her mother lying there and unresponsive.

A team spokesman said Schoeneweis had left the team, which was playing a doubleheader in Florida last night, and was returning to Phoenix.

"At this point, anything we can do to support Scott and his family, will be our focus," said Diamondbacks general manager Josh Byrnes, who was with the team. "I have talked to Scott Boras, the agent, a few times. We're trying to get the facts the best we can. It's devastating news. Everyone is taking it very hard."

Scott and Gabrielle Dawn Schoeneweis celebrated their 10th anniversary in January. They had three children together, and she already had a daughter when they were married.

Astros: Houston's Kaz Matsui was out without batting in the first inning of last night's game with Milwaukee because of an incorrect lineup card. The official batting order submitted before the game had Matsui batting first, but Michael Bourn led off instead. Bourn singled to right off Yovani Gallardo, but the hit was nullified when Brewers manager Ken Macha showed the umpires the mistake. Matsui was called out while he was still in the on-deck circle and Bourn batted again, drawing a walk.
