SEATTLE (AP) - Daniel Nava hit a two-out single in the top of the 10th inning to score pinch-runner Jackie Bradley Jr., and the Boston Red Sox rallied from a four-run deficit for the second time in a four-game series to beat the Seattle Mariners 8-7 in 10 innings on Thursday.
Ryan Lavarnway walked to open the 10th against Seattle's Tom Wilhelmsen (0-3) and was replaced by Bradley. Brady Holt laid down a sacrifice bunt to get Bradley to second base with one out. Wilhelmsen struck out Iglesias on the eighth pitch of the at-bat then intentionally walked Jacoby Ellsbury.
Nava fell behind in the count, but was able to roll a 1-2 pitch back up the middle and past the dive of second baseman Brad Miller to give Boston the lead.
Koji Uehara pitched the 10th for his seventh save as the Red Sox took three of four in the series.
Boston also rallied from a 5-1 deficit to win the second game of the series 11-8.
