SEATTLE (AP) _ Dan Wilson, Seattle's No. 1 catcher, is expected to miss 3-4 weeks after injuring his left ankle while chasing a passed ball Sunday in a 4-1 loss to Kansas City.

Wilson severely sprained his ankle and sustained ligament damage. Manager Lou Piniella said the former All-Star will be placed on the 15-day disabled list for the first time in his career.

Wilson was injured when he went after a passed ball in an attempt to make a play at the plate. He caught his spikes when he left the dirt to go on to the artificial turf.

His ankle will be re-examined Monday. Dr. Mitch Storey, a team physician, said Wilson sustained a torn ligament.

``It's as serious an injury as I've ever had,'' said Wilson, on crutches after the game. ``I rolled my ankle.''

Wilson's ankle was wrapped in ice and an elastic bandage.

``There's never a good time to get injured,'' he said. ``Especially with things picking up around here. It's doubly tough.''

Despite the loss, the last-place Mariners finished with an 8-3 homestand.

``It's going to hurt us,'' Piniella said. ``Anytime you lose one of your regular players, it's going to hurt, especially at a key position like catcher.''

John Marzano, Wilson's backup, is the only catcher on Seattle's roster.

Piniella said the Mariners will recall catcher Raul Chavez from Triple-A Tacoma. Chavez will join the team for Tuesday night's game at Tampa Bay, Piniella said.

Wilson, an AL All-Star in 1996, is hitting .254 with eight homers and 40 RBIs in 83 games this season. He had a career-high six RBIs Friday night and hit three homers during the Mariners' homestand.
