Joseph Hilarian Hatten (November 7, 1916 – December 16, 1988) was an American professional baseball pitcher who appeared in 233 games pitched in Major League Baseball for the Brooklyn Dodgers and Chicago Cubs from to mid-. Born in Bancroft, Iowa, he threw left-handed, batted right-handed and was listed as tall and . Hatten started in pro ball at age 20 with Crookston in the old Northern League in 1937. Acquired by the Montreal Royals from the Minneapolis Millers of the American Association in the 1941–42 off-season, Hatten pitched for the Royals briefly in 1942 before entering the U.S. Navy. Upon his discharge four years later, he first saw service with the Brooklyn Dodgers. Possessing a "rubber arm", Hatten worked as both a starting pitcher and a reliever, even appearing in both ends of a double-header. Hatten's first year in the big leagues in 1946 saw him post a 14–11 won-lost record with a 2.84 ERA, eighth-best in the National League. He followed that season with a career-high 17 wins, eight losses and a 3.63 ERA. Hatten often had trouble controlling his pitches, as he allowed the second-most bases on balls in each of his first two seasons with the Dodgers, walking 110 batters in 1946 and 105 in 1947. He also led the National League in hit batsmen with seven in 1946. In 1948, Hatten threw 51 pitches in a five-inning complete game shutout against Cincinnati, the fewest pitches for a complete game in major league history. The Dodgers won the and NL pennants during Hatten's stay, and he would appear in six World Series games, all against the New York Yankees. In 1947, he started Game 3 at Ebbets Field. Staked to a 6–0 lead after two innings and a 9–4 advantage after four, Hatten was driven from the contest with one out in the fifth after allowing a two-run home run to Joe DiMaggio. Brooklyn held on to win, 9–8, but the victory was awarded to relief ace Hugh Casey. His other five Fall Classic appearances would come in relief, three in 1947 and two in 1949. Over Hatten's six games pitched, he did not earn a decision or a save; in 10 total innings, he allowed ten earned runs on 16 hits and nine bases on balls, striking out five. His career World Series earned run average was 8.44. Hatten won 59 games (losing 39) for the
