Guillermo Heredia’s two-out pinch RBI single in the ninth inning Thursday night lifted the Mariners to a 5-4 walk-off victory over the Chicago White Sox.
And saved them from the potential sting of a crushing loss.
The Mariners let a 4-0 lead slip away when reliever Casey Lawrence served up a two-run homer in the seventh inning to Matt Davidson before Dan Altavilla gave up successive two-out homers in the eighth inning.
Taylor Motter started the winning rally with a leadoff single to right against White Sox lefty Dan Jennings.
After Jarrod Dyson fouled off two bunts in attempting to sacrifice, he got one into fair territory — but right back to Jennings, who threw out Motter for a force at second.
