DALLAS - Milan Michalek scored San Jose's first power-play goal of the series with 16:34 left and the Sharks beat Dallas 2-1 on Wednesday night to avoid being swept in the Western Conference semifinals.
Sharks captain Patrick Marleau had tied the game with another short-handed goal, getting one after a turnover by Sergei Zubov for the second straight game.
Game 5 is Friday night in San Jose, where the Stars won the first two games of the series. The visiting team has won 14 of the past 18 games between the Pacific Division rivals, dating to last season.
The Stars missed a chance for their first post-season series sweep since 1999, when they swept Edmonton in the first round and went on to win the Stanley Cup.
