Watch: Ortiz blasts his longest HR of the season

David Ortiz doesn't get cheated.

In the fourth inning against the San Francisco Giants, Ortiz got a gift from his former teammate Jake Peavy - an 85-mph cutter that was a little low, and a little inside.

Big Papi didn't miss it, and tattooed his longest home run of the season, a 442-foot shot, into the right-field bleachers at Fenway.

The home run was his 23rd of the season and it came off the bat at 108 mph.
