BOSTON (AP) – It looks like David Ortiz’s eyesight isn’t the cause of his season-long slump.

His vision checked out “very well” during an examination Monday, and the Boston Red Sox designated hitter was given drops for dry eyes, team spokesperson Pam Ganley said.

Ortiz has two homers and 22 RBIs with a .197 batting average in 51 games. In his other six years with Boston he averaged 38.5 homers and hit below .287 just once when he batted .264 in an injury-plagued 2008 season.

Ortiz has been dropped from the third to the sixth spot in the lineup, but has hit better recently. He has a six-game hitting streak with seven hits in 25 at-bats, raising his average from .185.

Center fielder Jacoby Ellsbury is day-to-day with a strained right shoulder after tests showed no structural damage, Ganley said. He was hurt when he slid into second base in the third inning of Sunday’s 6-3 loss to the Texas Rangers and left the game after five innings.

Boston begins a three-game series at home against the New York Yankees on Tuesday night.
