Thursday, September 1, 1960---Roberto Clemente homered for the third straight day as the Pirates (79-49) beat SF 6-1. Clemente hit a 3-run shot (his 13th) with Skinner (single) and Nelson (double) aboard in the first inning off Georges Maranda (1-3). The Giants got one back in the bottom of the first when Andre Rodgers tripled and scored on a Willie Mays single. The Giants were constantly threatening. Harvey Haddix struck out Willie Kirkland with 2 men aboard to end both the first and third innings.
Maranda singled in the fourth inning and appeared to score the Giantsí second run when Rodgers hit what looked like a 2-out single to left. But Miranda was called out for missing third base to end the threat. Clem Labine replaced Haddix during the sixth inning after Haddix had given up a total of 10 hits. Labine pitched the final 3 1/3 innings of shutout ball and the Pirates scored 2 more in the eighth on a walk to Nelson, a Clemente single, an error by Maranda allowing Nelson to score and a sacrifice bunt by Labine that scored Clemente. The Bucs made it 6-1 in the ninth on a double by Groat and a single by Nelson. Haddix (10-8) got the win and Labine got his second save. Labine lowered his Pirates ERA to 1.88 and now had 13 strikeouts in 14 1/3 innings since joining the Pirates. The Dodgers and Tigers, both of whom had given up on the 34-year old Labine during the season, must have wondered what had gotten into him. Clemente (.323) had his second consecutive 3-hit game, and Nelson (.292) and Haddix (.255) each had a pair of hits. The Pirates led the Braves and Cardinals by 7 games.
With the rosters expanded for September, the Pirates called up lefthander Diomedes Olivo, first base prospect R.C. Stevens, 31-year old infielder-outfielder Harry Bright, Jim Umbricht and Bennie Daniels, who had both been optioned in June, Earl Francis, and activated first base coach Mickey Vernon. Bright had spent the 1959 season on the Pirates bench but had been toiling primarily in the minors since 1946. Mickey Vernon was 42. Olivo was a 41-year old rookie. Ted Williams was a few months older than Olivo. When Williams retired effective September 29, 1960, Vernon and Olivo became 1-2 as the oldest players in MLB.
