ARLINGTON, Texas - The Texas Rangers purchased the contract of left-hander Tony Mounce from Triple-A Oklahoma on Monday and put him in their starting rotation.

Mounce is scheduled to start tonight at Seattle. He will take the spot in the rotation of opening day starter Ismael Valdes, a right-hander the Rangers have indicated they won't re-sign.

Manager Buck Showalter said the Rangers want to get another look at Mounce before the season ends. Mounce made his major league debut for the Rangers in June and went 1-4 with a 6.38 ERA in eight starts.

ORIOLES: Designated hitter David Segui had surgery Monday to repair a tendon in his left wrist.

Segui, who hasn't played since July 25, finished the season the way he started it: on the disabled list. In between, he hit .263 with five homers and 25 RBI in 67 games.

The surgery was performed by Dr. Thomas Graham at the Curtis National Hand Center at Union Memorial Hospital. Dr. Graham used a piece of tissue to build a bridge to hold the damaged tendon down.
