senator, John M. Walker, wrote to US Senator Hugh Scott requesting an early release on March 4 so Clemente could join the team for spring training. Pittsburgh Pirates, 1960s Early in the 1960 season, Clemente led the league with a .353 batting average, and the 14 extra-base hits and 25 RBIs recorded in May alone resulted in Clemente's selection as the National League's Player of the Month. His batting average would remain above the .300 mark throughout the course of the campaign. On August 5 at Forbes Field, Clemente crashed into the right-field wall while making a pivotal play, depriving San Francisco's Willie Mays of a leadoff, extra-base hit in a game eventually won by Pittsburgh, 1–0. The resulting injury necessitated five stitches to the chin and a five-game layoff for Clemente, while the catch itself was described by Giants beat writer Bob Stevens as "rank[ing] with the greatest of all time, as well as one of the most frightening to watch and painful to make." The Pirates compiled a 95–59 record during the regular season, winning the NL pennant, and defeated the New York Yankees in a seven-game World Series. Clemente batted .310 in the series, hitting safely at least once in every game. His .314 batting average, 16 home runs, and defensive playing during the course of the season had earned him his first spot on the NL All-Star roster as a reserve player, and he replaced Hank Aaron in right field during the 7th and 8th innings in the second All-Star game held that season (two All-Star games were held each season from 1959 through 1962). During spring training in 1961, following advice from Pirates' batting coach George Sisler, Clemente tried to modify his batting technique by using a heavier bat to slow the speed of his swing. During the 1961 season, Clemente was named the starting NL right fielder for the first of two All-Star games and went 2 for 4; he hit a triple on his first at-bat and scored the team's first run, then drove in the second with a sacrifice fly. With the AL ahead 4–3 in the 10th inning, he teamed with fellow future HOFers Hank Aaron, Willie Mays, and Frank Robinson to engineer a come-from-behind 5–4 NL victory, culminating in Clemente's walk-off single off knuckleballer Hoyt Wilhelm. Clemente started again in right field for the second All-Star game held that season
