The Red Sox have won five straight games (thanks to Franchy Cordero's bottom-of-the-10th grand slam which also gave Boston its first walkoff win of the season) and nine of their last 12.
Cordero's blast was the first walkoff extra-innings grand slam allowed by the Mariners since May 2010, when Kendrys Morales of the Angels broke his leg jumping on home plate. It was the Red Sox's third walkoff grand slam against the Mariners, though the first in extras. The earlier slams both came in 1998: Mo Vaughn (April 10, an epic home opener)) and Nomar Garciaparra (September 2).
