LOS ANGELES -- Reds shortstop Jerry Hairston Jr. exited Wednesday's Reds-Dodgers game in the first inning because of dizziness caused by dehydration.
Batting in the top of the first, Hairston grounded to third base and ran slowly up the line as he was easily retired.
Rookie Paul Janish replaced Hairston in the bottom of the first.
Hairston is batting .309 with one home run and six RBIs in 22 games this season.
Keeping a shortstop healthy has been an ongoing issue for the Reds this season. Alex Gonzalez has been out since Spring Training with a compression fracture in his left knee. His replacement, Jeff Keppinger, was having a good season until he fractured his left kneecap on a foul tip on May 13. Keppinger is out four to six weeks.
