SEATTLE — The Mariners finished off a sweep of the White Sox Thursday as an ugly throwing error by Josh Rojas in extra innings kept Seattle alive to walk it off with an RBI single. The Sox’ deflating loss closed out a 2-4 road trip that still showed signs of promise for the rebuilding team.

Dominic Canzone singled home the winning run in the 11th inning and the Seattle Mariners completed a three-game sweep of the Chicago White Sox with a 4-3 victory.

In a game where it seemed they might find any possible way to hinder a successful outcome, the Mariners managed to pull out an extra-inning win Thursday and sweep the White Sox.
