WEST PALM BEACH, Fla. -- Astros outfielder Derek Fisher said he was fine after jarring his left shoulder while trying to make a diving catch on a ball off the bat of Miguel Cabrera. Fisher left the game in the first inning of Houston's 5-3 loss to the Tigers on Thursday afternoon in Lakeland, Fla.

“I did some light tests and everything was fine,” said Fisher, who has already been optioned to Minor League camp. “It was more precautionary, just the way it happened and the way it looked more than anything. More importantly, everything’s been checking out fine and I should be good.”

Fisher said his instincts took over when he dove for the ball.

“That kind of stuff happens when you’ve got a bunch of competitors on the field,” he said. “You try to catch it if it’s there and see what happens later.”

Fisher will start the season in the outfield at Triple-A Round Rock. He has played in 95 games with the Astros over the last two years and scored the game-winning run in Game 5 of the 2017 World Series against the Dodgers. Fisher went 12-for-40 this spring with two doubles, two homers and six RBIs, with seven walks and eight strikeouts in 47 plate appearances before being optioned to Minor League camp on Tuesday.

Worth noting

• The Astros will hold a news conference at 3:30 p.m. CT Friday at the FITTEAM Ballpark of the Palm Beaches, where they’re expected to announce a contract extension for All-Star third baseman Alex Bregman. Astros owner Jim Crane, president of baseball operations and general manager Jeff Luhnow and manager AJ Hinch will be in attendance.

MLB.com reported Tuesday that Bregman will sign a $100 million contract that will cover his three arbitration years (2020-22) and his first two years of free agency ('23-24).

• Outfielder Yordan Alvarez was scratched from the lineup Thursday and didn’t make the trip to Lakeland. The Astros said it wasn’t related to an injury or any disciplinary reasons.
