The contract for Zito, 2-2 with a 4.54 ERA in his third major league season, runs through 2005 with a club option for 2006. It contains numerous bonus opportunities.

"It feels good," he said. "When a team locks a player up, it shows they have faith in him."

Zito combines with Mark Mulder and Tim Hudson to form one of baseball's most dynamic young starting rotations. Both Mulder and Hudson also are under contract until 2005.

Zito was unsure of the terms of the contract. He said he did not discuss specific numbers with his agent, Arn Tellem, when the deal was struck Monday night.

"I have as many clothes as I can wear. I have a truck that I like. And I have a place to live," he said. "What's nice is the peace of mind."

- SEGUI TO DL: Orioles designated hitter David Segui said that he has a torn tendon in his left wrist and will need surgery to repair the injury.

Segui was to be examined again by a team doctor on Tuesday night, but Baltimore's first baseman and designated hitter appears headed for another trip to the disabled list.

Segui has played in only three games since hurting his wrist April 26 in Kansas City. The injury occurred when he was stepped on during a play at the plate.

- BOSOX SUSPENDED: Boston pitcher Frank Castillo was suspended for five games for hitting a batter last Sunday, and teammate Trot Nixon was suspended four for throwing his bat at a Tampa Bay pitcher.

Both also were fined Tuesday by Bob Watson, baseball's vice president in charge of discipline, as was Devil Rays pitcher Ryan Rupe. Watson said Rupe intentionally hit Nomar Garciaparra and Shea Hillenbrand with pitches.

The Major League Baseball Players Association appealed, meaning the suspensions cannot start until after a hearing before Bob DuPuy, baseball's chief operating officer.
