The Yankees continued to win games, making up ground and by the time they met Boston for a pivotal four-game series at Fenway Park in early September. Going into the series, the Yankees were four games behind the Red Sox. The Yankees swept the Red Sox in what became known as the "Boston Massacre," winning the games 15–3, 13–2, 7–0, and 7–4. The third game was a shutout pitched by "Louisiana Lightning" Ron Guidry, who led the majors with nine shutouts, a 25–3 record, and a 1.74 ERA. On the last day of the season, the two clubs finished in a tie for first place in the AL East, and a tiebreaker game was held at Fenway Park. With Guidry pitching against former Yankee Mike Torrez, the Red Sox took an early 2–0 lead. In the seventh inning, light-hitting Yankee shortstop Bucky Dent drove a three-run home run over the Fenway Park's Green Monster, putting the Yankees up 3–2. Reggie Jackson's solo home run in the following inning sealed the eventual 5–4 win that gave the Yankees their one hundredth win of the season and their third straight AL East title. Guidry earned his 25th win of the season.
