James Gilbert Stump (February 10, 1932 – November 19, 2015) was an American professional baseball player who appeared in 11 Major League Baseball games as a relief pitcher for the 1957 and 1959 Detroit Tigers.
He threw and batted right-handed, stood 6 feet (1.8 m) tall and weighed 188 pounds (85 kg).
Stump signed with the Tigers in 1951 and his first two minor league seasons — sandwiched around a two-year military stint during the Korean War — were noteworthy, as he won 30 of 43 decisions (.698).
After winning 14 games for the 1957 Birmingham Barons of the Double-A Southern Association, Stump made his Major League debut for the Tigers against the Boston Red Sox at Briggs Stadium, working one inning in relief and giving up a hit, a run and two bases on balls, including one to Ted Williams, in a 6–1 Tiger defeat.
But, overall, Stump's first trial with Detroit was successful; he appeared in five more games played, won his only decision, and surrendered a total of only three earned runs in 13?1/3 innings, for a sparkling 2.08 earned run average.
The next two seasons, Stump put up identical 8–11 records with the Triple-A Charleston Senators, before receiving his second and final audition with the Tigers in 1959, pitching in 11?1/3 innings and posting another strong ERA (2.38).
He played two more seasons of minor league ball — ironically, posting a third straight 8–11 season in the American Association in 1960 — and retired after the 1961 campaign.
