The Cincinnati Reds give Fogg an opportunity to win a spot in a rotation after Aaron Harang and Bronson Arroyo.
Fogg was drafted by the Chicago White Sox in the third round of the 1998 Amateur draft. He made his major league pitching debut September 2, 2001. He was traded to the Pittsburgh Pirates in December of that year for pitcher Todd Ritchie. He signed with the Rockies prior to the 2006 season.
The most impressive start of Fogg's career came on June 30, 2006, against the Seattle Mariners at Safeco Field in Seattle, Washington. While pitching for the Colorado Rockies, Fogg threw a two-hit complete game shutout while facing the minimum 27 batters. All three Mariners who reached base (Adrian Beltre and Kenji Johjima on singles and Raul Ibanez on a base on balls) were erased on double plays by infielders Garrett Atkins, Clint Barmes, Jamey Carroll, and Todd Helton.
During the 2007 season Fogg acquired the nickname "dragon-slayer" after he pitched and won against many of the best pitchers in the majors including Brandon Webb and Curt Schilling.
Josh started game 3 of the 2007 World Series against the Boston Red Sox.
