Pinch hitter Bill Stein drove in the tie-breaking run with a double, and Texas added two runs in the 10th inning yesterday as the Rangers beat the Brewers, 4-1, spoiling Milwaukee's home opener.

Rollie Fingers, who was presented the American League's Cy Young and most valuable player trophies for 1981 in pregame ceremonies, suffered his second defeat in three decisions. He started the 10th by giving up a single to Mike Richardt. Mark Wagner followed with a single and Richardt took third.

Stein followed with his double off the glove of Kevin Bass, who tried to make an over-the-shoulder catch in right field.

Lee Mazzilli singled in a run one out later and stole second. After an intentional walk to Buddy Bell loaded the bases, a sacrifice fly by Leon Roberts scored the third run of the inning.

Fingers was sidelined for 10 days during spring training after suffering a slight separation of his left shoulder. However, he refused to blame the injury for the loss.

"My arm felt fine," he said. "It was one of those days when I just had nothing."

The game, delayed at the start for 34 minutes because of rain, drew 49,887, the fifth largest home-opening crowd in Brewers' history. The Brewers' first two home games were postponed last week because of snow.
