CLEVELAND (AP) _ Cleveland Indians outfielder Brian Giles signed a three-year contract extension Tuesday with a club option for the 2002 season.

Giles, 27, had been signed just through this year. Terms of the deal were not disclosed.

``It's a good deal for both sides,'' Giles said. ``I got a little security for myself but the big thing is staying here in Cleveland.

``Since I've been here we've been in the running for a world championship, so it is exciting to be here.''

Giles hit a game-winning, three-run homer Monday night in Cleveland's 6-5 win against the Seattle Mariners and is batting .421 so far this season. He has four homers and nine RBIs in 11 games.

A 17th-round pick by Cleveland in the 1989 amateur draft, last season was the first Giles spent entirely at the major league level. He hit .268 with 17 home runs and 61 RBIs.
