SEATTLE -- Pinch-hitter Guillermo Heredia's two-out single in the ninth inning scored Jarrod Dyson from second base to give the Seattle Mariners a 5-4 win over the White Sox on Thursday night.
Batting for Ben Gamel, Heredia looped a breaking ball from Dan Jennings (2-1) into shallow right-center field and allowed the speedy Dyson to race home from second with the winning run after Seattle's bullpen blew a 4-0 lead.
Seattle's Jean Segura matched the longest hitting streak in baseball this season with a three-run home run early in the game and Dyson added a solo shot.
Chicago rallied also thanks to the long ball. Matt Davidson hit a two-run homer in the seventh inning, and Todd Frazier and Tim Anderson added back-to-back solo shots off Seattle reliever Dan Altavilla with two outs in the eighth to tie it.
Seattle reliever Nick Vincent (2-1) settled the shaky bullpen with a perfect ninth inning to get the victory.
