Angels starter C.J. Wilson, who hasn’t recorded a victory since June 26, gave up seven runs (six earned) over five innings.
Pedroia doubled in the first inning and scored on a single to center field by Gonzalez. Then the Sox dropped five on Wilson in the second inning.
Podsednik and Ellsbury had RBI singles before Pedroia launched a fastball over the wall for his 11th homer.
Trailing, 8-7, the Sox took the lead back in the sixth inning with two runs.
Mike Aviles pounded a Jason Isringhausen pitch into the Monster Seats. With two outs, doubles by Ciriaco and Ellsbury off Jordan Walden gave the Sox a 9-8 lead.
Facing Andrew Bailey with two on in the seventh, Trout, down 1-and-2 in the count, worked the count full, fouled off a 96-mile-per-hour fastball, then singled to left to tie the game again.
“The last couple of innings we didn’t hold them and that’s my fault,” Valentine said.
