pitched another four-hit shutout. Then, two days later in game five, he threw a six-hit shutout to clinch the series for the Giants. In a span of only six days, Mathewson had pitched three complete games without allowing a run, while giving up only 14 hits. The next year, Mathewson lost much of his edge, owing to an early-season diagnosis of diphtheria. McGraw pulled over 260 innings from him, but these were plagued with struggle. Though he maintained a 22–12 record, his 2.97 earned run average was well above the league average of 2.62. His 1.271 walks plus hits per innings pitched, quite uncharacteristic of him, was due to an increased number of hits and walks. By 1908, Mathewson was back on top as the league's elite pitcher. Winning the most games of his career, 37, coupled with a 1.43 earned run average and 259 strikeouts, he claimed a second triple crown. He also led the league in starts, innings pitched, complete games, and shutouts, and held hitters to an exceptionally low 0.827 walks plus hits per innings pitched. He even led the league in saves, racking up 5 of them in 12 relief appearances. Unfortunately, the Giants were unable to take home the pennant due to what was ultimately known as Merkle's Boner, an incident that cost the Giants a crucial game against the Chicago Cubs, who eventually defeated the Giants in the standings by one game. Mathewson returned for an outstanding 1909 season; though not as dominant as the previous year, he posted a better earned run average (1.14), and a record of 25-6. He repeated a strong performance in 1910 and then again in 1911, when the Giants captured their first pennant since 1905. The Giants ultimately lost the 1911 World Series to the Philadelphia Athletics, the same team they had defeated for the 1905 championship. Mathewson and Rube Marquard allowed two game-winning home runs to Hall of Famer Frank Baker, earning him the nickname, "Home Run". Mathewson, the team's "star pitcher", signed a three-year contract with the Giants in late 1910, for the upcoming 1911, 1912 and 1913 seasons, the first time he had signed a contract over a year in length. In 1912, Mathewson gave another stellar performance. Capturing the pennant, the Giants were fueled by the stolen-base game and a superior pitching staff capped by Rube Marquard, the "11,000-dollar lemon" who turned around to
