Tony Bernazard's bases-loaded bloop single, his fourth hit of the game, scored the winning run in the bottom of the ninth inning to give the White Sox a 2-1 victory over the Baltimore Orioles last night in Chicago.

Wayne Nordhagen opened the ninth with a grounder to Mark Belanger, who threw the ball over the first baseman's head for a two-base error. Rusty Kuntz, running for Nordhagen, went to third on Greg Pryor's infield single. Reliever Sammy Stewart (0-1) then walked Bob Molinaro to load the bases before Bernazard hit a short fly ball behind third base.

Chicago starter Britt Burns (1-0) yielded only four hits and struck out five in his complete game.

Chicago took a 1-0 lead in the second off Baltimore starter Jim Palmer. Greg Pryor drew a two-walk and went to third after Bill Almon walked and Palmer was charged with a wild pitch. Bernazard then singled hom Pryor.

The Orioles tied it in the fifth when Doug DeCinces led off with a bunt single. He went to second when Pryor mishandled Rick Dempsey's grounder for an error and both runners advanced on Belanger's sacrifice. With Al Bumbry at the plate, Chicago catcher Carlton Fisk was charged with a passed ball, allowing DeCinces to score.
