CLEVELAND, Ohio -- When the Indians resume the season Friday in Oakland, they will do so without right fielder Lonnie Chisenhall.

Chisenhall, who leads the team with 51 RBI, will be placed on the disabled list before Friday's game. The Indians will replace Chisenhall with Tyler Naquin, who opened the season with the Tribe, but was optioned to Class AAA Columbus in mid-April.

The Indians, who open the second half in first place in the AL Central with a 47-40 record and a 2 1/2 game lead over the Twins, lost second baseman Jason Kipnis to a right hamstring injury on Saturday and Chisenhall to a right calf injury on Sunday.

Chris Antonetti, Indians president of baseball operations, said Kipnis could be back sooner than Chisenhall. Antonetti said Chisenhall could be out a "few weeks." This will be Chisenhall's third stay on the DF this year.

Chrisenhall is having a career season. He's hitting .305 (57-for-187) with 12 homers, 51 RBI and a .953 OPS.
