Talk about a momentum swing.

David Ortiz changed the momentum of the 2013 ALCS with one swing of the bat - a game-tying grand slam in the eighth inning of Game 2, setting up Jarrod Saltalamacchia's walk-off single in the ninth as the Red Sox rallied for a 6-5 win on Sunday night to tie the series 1-1.

The incredible awakening for the Sox offense came after Tiger's starter Max Scherzer pitched a gem for seven innings, striking out 13 while allowing just two hits, two walks and one run.

Ortiz's slam came off Joaquin Benoit and barely made it over the wall in right center field, a low liner that Detroit's Torii Hunter nearly snagged out of the air before he, and the ball, went over the wall.

Detroit built a 5-0 lead through the first six innings with the help of 3-RBI's from Alex Avilla, including a home run, and a solo-blast from Miguel Cabrera - all coming against Clay Buchholz, who was charged with five earned on eight hits through 5 2/3 innings.

Game 3 is Tuesday night in Detroit with Justin Verlander taking on Boston's John Lackey.
