The Twins placed Kepler on the 10-day injured list Thursday with left patellar tendinitis, Bobby Nightengale of the Minneapolis Star Tribune reports. Kepler had missed four straight games and started just three of the last 11 contests because of the nagging knee issue. The Twins have finally opted to put him on the IL, bringing up DaShawn Keirsey as a replacement. Most of the playing time in right field while Kepler is sidelined should go to Matt Wallner.
