CHICAGO (AP) _ Sammy Sosa hit his 52nd homer of the season Tuesday night, tying Willie Mays' NL record for most home runs in August.

Sosa hit a towering shot in his first at-bat, sending Ryan Dempster's 2-1 pitch over the left-field fence for a two-run homer in the first inning. The crowd was roaring as soon as the ball left Sosa's bat, and it didn't stop until he came out for a curtain call.

It was Sosa's 17th homer this month, tying the mark set by Mays in August 1965. The major league record for homers in August is 18, set by Detroit's Rudy York in 1937.

Sosa holds the major league mark for homers in any month, hitting 20 in June 1998. He and York are the only two players in major league history with two, 17-homer months. York hit 17 in August 1943.

The homer also gave Sosa 438 for his career. That ties him for 27th on the all-time list with Andre Dawson _ who just happened to be at Wrigley on Tuesday night. Dawson was on hand as the Cubs gave out replicas of his 1988 Topps baseball card.
