Saturday, September 10, 1960---The magic number for the Pirates was 13 as the Bucs (84-52) beat the Cubs 4-1 while the Cardinals were losing to the Phillies to fall into a tie with the Braves 7 games back. Bob Friend was aided by 5 double plays, and Bill Mazeroski (naturally) was involved in all five. Dick Stuart gave Friend a 1-0 lead in the second with his 19th HR of the season. In the fourth, Clemente led off by reaching on an Ernie Banks error and Stuart followed with a single. Clemente advanced to third on a fly out by Burgess and scored on a single by Hoak.
Mazeroski bounced to the pitcher, but Bob Anderson (7-10) threw the ball away going for the force at second, allowing Stuart to score. Schofield then doubled, as Hoak scored and Mazeroski was thrown out at the plate on the relay throw from shortstop Ernie Banks. The Cubs scored their only run in the seventh on singles by Ed Bouchee, Al Heist and Don Zimmer. Zimmer was 3 for 3 with a stolen base. Stuart (.259) had 3 hits for the Pirates. Dick Schofield (.283) had a double in three at bats, giving him at least one hit in each of the 4 games since he had replaced the injured Groat. Friend (15-11) scattered 9 hits, walked 1 and struck out 6 in pitching his 14th complete game. His ERA was 2.99.
Meanwhile, a Yankee win and a Baltimore loss put NY ½ game ahead of the Orioles atop the A.L. The Yankee win, a 5-1 affair in Detroit, featured a 643-foot home run by Mickey Mantle.
