MESA, ARIZ. ? Kerry Wood left the Chicago Cubs’ 6-5 loss to the Texas Rangers on Wednesday before the third inning because of tightness in his right shoulder.

Wood, set to start opening day, took his warmup tosses in the bottom of the third, but walked off the field after talking with a trainer. He called his exit from the game “precautionary.”

“The inning before, I felt tightness in the shoulder,” Wood said. “Everything felt great. I came in and sat down, and everything felt great. It was just a little bit of tightness, and it’s too early to be messing around with anything right now. We thought it would be best to shut it down for the day.”

The 27-year-old Wood missed the entire 1999 season after undergoing Tommy John surgery and he was out for two months last year with tendinitis in his right triceps. Wood was examined Wednesday by a teams doctor and Cubs trainer Mark O’Neal who described the ailment as “generic shoulder tightness.”

Wood said he would be able to make his scheduled start Monday against the Chicago White Sox. On Wednesday, he gave up two hits and one run in two innings, walking two and striking out one.

Rangers starting pitcher Chan Ho Park worked three innings, giving up four hits and three runs, striking out three and walking none.

Mark Teixeira was 2-for-3 with a run scored and an RBI for the Rangers.

At Sarasota, Fla., the Cincinnati Reds announced center fielder Ken Griffey Jr. would play today for the first time this spring after taking a slow approach to his rehabilitation from a torn hamstring.

The Reds plan to use Griffey as a designated hitter in their home game against the Detroit after receiving permission for the league and the Tigers.

At Fort Myers, Fla., the Boston Red Sox expect Wade Miller to miss the first month of the season while he rehabilitates from a shoulder injury.

Heavy rains across Florida prompted the cancellation of all 10 Grapefruit League games scheduled for Wednesday.
