William Hambly Stoneman III (born April 7, 1944) is an American former professional baseball player and executive who, during his eight-year (1967–1974) pitching career in Major League Baseball, threw two no-hitters; then, as general manager of the Anaheim Angels (1999–2007), presided over the franchise's first-ever World Series championship in 2002.

Born in Oak Park, Illinois, Stoneman graduated from West Covina High School in southern California in 1962.

[4] The Vandals were one step from the College World Series in Omaha, but lost to Arizona in Tucson in the District 7 finals, today's "Super-Regionals" (Sweet 16).

After signing, Stoneman pitched at three minor-league classifications in 1966, with Rookie-level Caldwell, Single-A Lodi, and Double-A Dallas-Fort Worth.

He debuted as a starting pitcher with back-to-back assignments against the San Francisco Giants on July 16 and 21, allowing three total runs in 92⁄3 innings but gaining no decisions, although the Cubs won both games.

In the expansion draft of October 1968, Stoneman was selected by the Montreal Expos, where he spent five seasons and became a full-time starter for manager Gene Mauch.

[8][12][13][14] The second came at the end of the 1972 season on October 2, when he defeated the New York Mets in Montreal at Jarry Park, caught by Tim McCarver.

Stoneman also threw a one-hitter at home in 1971 against the San Diego Padres, a well-attended 2–0 win on Helmet Night on Wednesday, June 16.

The only hit came with one out in the seventh inning, a clean single to right field off the bat of Cito Gaston, which was the Padres' only well-struck ball of the night.

[24] After his playing career ended, Stoneman worked in banking in Canada, then joined the Montreal Expos' front office in November 1983, starting out in player relations.
