Forsythe went 1-for-5 with a solo homer in Saturday's 6-4 loss to the Red Sox.
The veteran made things momentarily interesting against closer Craig Kimbrel in the ninth with a 362-foot solo shot, his 20th round-tripper of the season. It marks the first time Forsythe has reached the milestone in his career and comes on the heels of his previous best of 17 homers he posted last season. The 29-year-old's season line now stands at a solid .274/.344/.464.
