Early career In 1912, the
New York Giants of the
National League obtained Shore for a trial from Guilford. He traveled with the team during the summer, often pitching
batting practice to Giants hitters. He made his major league debut on June 20 as a
relief pitcher, replacing
Hooks Wiltse in a 21–2
blowout against the
Boston Braves. Shore allowed ten runs in the ninth inning, though only three were
earned runs, as the Giants won 21–12. After the season, the
Baltimore Orioles of the Double-A
International League drafted Shore from Greensboro. Shore graduated from Guilford in June 1914 and reported to Baltimore on June 4. However, the
Federal League, a major league, had debuted in 1914 with the
Baltimore Terrapins competing directly with the Orioles; the Orioles struggled financially as they failed to draw fans to their games, forcing them to sell their best players. The Orioles sold Shore,
Babe Ruth, and
Ben Egan to the
Boston Red Sox of the
American League on July 9, With Baltimore, Shore won five games and lost three.
Boston Red Sox In his Red Sox debut against the
Cleveland Naps on July 14, 1914, Shore pitched a
complete game, allowing two hits. For the Red Sox in the 1914 season, Shore won ten games and lost five, pitching to a 2.00 ERA. Shore started the Red Sox'
Opening Day game in 1915. During the 1915 season, Shore pitched to a 19–8 win–loss record and a 1.64 ERA. The Red Sox won the American League pennant and faced the National League champion
Philadelphia Phillies in the
1915 World Series. Shore started Game 1 for the Red Sox against
Grover Cleveland Alexander, and lost by a score of 3–1. during the
1915 World Series In the 1916 season, Shore had a 16–10 win–loss record and a 2.63 ERA. The Red Sox again won the American League pennant and faced the
Brooklyn Robins in the
1916 World Series. Shore started Game 1 against
Rube Marquard. Leading the Robins by a score of 6–1 going into the ninth inning, Shore allowed three runs and was relieved by
Carl Mays, who allowed another run, as the Red Sox held on to win by a score of 6–5. Shore started Game 5 against
Jeff Pfeffer and allowed three hits to win the decisive game of the series as the Red Sox repeated as World Series champions. He allowed six runs, though only three of them were earned, in innings pitched in the 1916 World Series. He recorded nine
strikeouts while allowing four
walks. Shore then proceeded to retire the remaining 26 Senator batters without allowing a baserunner, completing a 4–0 Red Sox win.
Will Harridge, the
secretary of the American League, acknowledged Shore's feat as a
no-hitter. and for many years, the game was listed in the record books as a
perfect game. Debate over whether or not it should be considered a perfect game continued until
Fay Vincent,
commissioner of the major leagues, headed a committee on statistical accuracy in 1991 that clarified the definitions of a no-hitter and a perfect game. The committee determined that Shore did not pitch a perfect game, crediting the performance as a
combined no-hitter. It was the first combined no-hitter in MLB history. Shore's nine innings of no-hit ball in a combined no-hitter is still an MLB record, with it being matched only by
Francisco Cordova (who started his game) on July 12, 1997. Later in the 1917 season, as the Red Sox were again contending for the American League pennant, pitcher
Dutch Leonard broke his arm, leading the Red Sox to rely more on Shore in games. With the increased strain from his larger workload, Shore hurt his arm while throwing a
curveball during a game in September against Cleveland. He continued to pitch through the injury, but later said that he experienced stabbing pains in his shoulder and that his throwing arm was never the same as it had been before the injury. and the Red Sox finished the 1917 season in second place in the American League behind the
Chicago White Sox. He remained with the Red Sox for the completion of the 1917 season and reported to the Navy in October. The Navy assigned Shore to the
Boston Navy Yard, where he served as a
yeoman in the office of the paymaster He did not play for the Red Sox during the 1918 season, as they won the
1918 World Series. becoming the only major league player who enlisted in the Navy during World War I to receive an officer's commission. As the war had ended, Shore was discharged from the Navy in January 1919.
New York Yankees and later career On December 18, 1918, the Red Sox traded Shore, Leonard, and
Duffy Lewis to the
New York Yankees for
Ray Caldwell,
Frank Gilhooley,
Slim Love,
Roxy Walters, and $15,000 ($ in current dollar terms). Shore contracted the
mumps from teammate
Ping Bodie and did not fully recover until after the season; he pitched to a 5–8 record and a 4.17 ERA for the Yankees during the 1919 season. Hoping to rebound in the 1920 season, Shore had a 2–2 record with a 4.87 ERA. After the 1920 season, the Yankees sent Shore,
Truck Hannah,
Bob McGraw, and
Ham Hyatt to the
Vernon Tigers of the Double-A
Pacific Coast League (PCL) in order to acquire
Johnny Mitchell. Shore struggled with Vernon, who returned him to the Yankees in May. Rather than accept Shore, the Yankees sold him to the PCL's
San Francisco Seals in June. Between Vernon and San Francisco, Shore won two games and lost five. His rights reverted to Vernon, but Shore asked for and received his release from the Tigers. ==Later life==
