William James Duggleby (March 16, 1874 – August 30, 1944), nicknamed "Frosty Bill", was a pitcher for the Philadelphia Phillies. He played from 1898 to 1907. He also played two games for the Philadelphia Athletics in 1902 and nine games for the Pittsburgh Pirates in 1907. Duggleby is the first of four major league players to hit a grand slam in his first major league at-bat; Jeremy Hermida, Kevin Kouzmanoff and Daniel Nava are the other three. As of 2011[update], he still holds the Phillies team record for hit batsmen for a career (82).
Duggleby was one of the "jumpers" who left the Phillies in 1902 for other teams, including (in Duggleby's case) Connie Mack's new American League team, the Athletics. The Phillies filed suit to prevent the "jumpers" — in particular, Nap Lajoie, Bill Bernhard, and Chick Fraser — from playing for any other team, a plea which was rejected by a lower court before being upheld by the Pennsylvania Supreme Court. Duggleby was the first of the "jumpers" to return to the Phillies, on May 8, 1902, after playing only two games with the A's.
