SAN DIEGO (Ticker) -- Tony Gwynn's march toward his 3,000th hit was sidetracked after the San Diego Padres placed the eight-time batting champion on the 15-day disabled list tonight. Gwynn, 39, suffered a strained left calf muscle in Friday night's 5-4 victory over the Cincinnati Reds. He was injured while running out a ground ball in the first inning and had to be helped off the field by members of the training staff. "Right out of the box it just grabbed me. I topped the ball so I knew I had to go," Gwynn said Friday. "It's one of those things that happens. I know I'll be out two weeks, after that we'll see what happens. "At first I thought the bat might've wrapped around my ankle. I came in and iced it and I can still feel it from the middle of my calf to the back of my knee." To fill Gwynn's roster spot, the Padres recalled outfielder Mike Darr from Triple-A Las Vegas. Gwynn has 2,975 hits, leaving him 25 shy of becoming the 22nd player to reach the 3,000-hit plateau. Gwynn, Wade Boggs of Tampa Bay and Cal Ripken of Baltimore all are expected to reach 3,000 hits this season. Boggs needs 53 and Ripken 104. Gwynn is batting .333 with three homers and 19 RBI in 38 games this season. Last year, he hit .321 with 16 homers and 69 RBI, helping lead the Padres to the World Series. Only Hall of Famer Ty Cobb has won more batting titles (12) than Gwynn, who shares the National League record with Honus Wagner. Darr, 23, was hitting .274 with 10 RBI and two stolen bases in 26 games for the Triple-A Stars. A second-round pick of Detroit in the 1994 draft, he was acquired from the Tigers in March 1997 in a trade for second baseman Jody Reed. Darr was a Southern League All-Star last season after being named Padres Minor League Player of the Year in 1997.
