Mike Schmidt, who earlier had homered, hit a two-out, two-run double in the top of the 11th inning last night to give the Philadelphia Phillies a 5-3 victory over the Giants in San Francisco.

Philadelphia second baseman Manny Trillo set a National League record by handling his 419th chance without an error. The old record was set by Ken Hubbs in 1962.

After flubbing his first chance of the season, Trillo has gone 79 straight games without an error. Ken Boswell holds the record of 85.

Schmidt, whose homer was his first at Candlestick Park since July 20, 1979, provided the victory for reliever Ron Reed (3-2). Sid Monge got the last two outs for his first save.

With two out in the 11th, Pete Rose and Greg Gross singled off reliever Fred Breining (4-3), the fourth Giant pitcher. Jim Barr relieved and Schmidt lined a one-two pitch off the center-field fence.

Schmidt gave the Phillies a 3-2 lead with a bases-empty homer in the eighth, but the Giants tied the game in the ninth on a one-out, run-scoring single by Joe Morgan.

The Giants had a chance to win the game in 10th when they had runners at first and third with one out. But Reed got Jim Wohlford to hit into a double play.
