The Grizzlies are proving they know how to grab an advantage and hold onto it this postseason.

Tony Allen scored on a driving layup to open overtime and the Grizzlies held off the Oklahoma City Thunder 103-97 on Monday night to push the defending Western Conference champions to the edge of elimination.

The Grizzlies shook off a first half in which they couldn't hit shots and the Thunder seemingly couldn't miss in building their largest lead in this series to 17 points. But the Grizzlies have yet to lose on their home court this postseason, and they won their third straight and seventh in eight games to grab a 3-1 lead in the series.
