Guerrero (back) is in the starting lineup for Tuesday's game against the Red Sox.
After missing the final two games of the most recent series against the Yankees with back tightness, Guerrero is back at first base and batting third in the order. The 27-year-old slugger has struggled with hitting the long ball, as he has yet to hit one over the fence since May 17. Guerrero has slashed .280/.372/.366 in 288 plate appearances on the campaign.
