Isaac played for the Dunedin, FL team in the Little League World Series in 1991. The Toronto Blue Jays drafted him in the 48th round of the 1998 amateur draft but he opted instead to go to college to play for Brigham Young University.
Iorg then went on a mission for two years to East Los Angeles, CA.
Despite having been away from competitive baseball for a couple years, Toronto selected Iorg in the 19th round of the 2001 amateur draft. Assigned to the Medicine Hat Blue Jays, he hit .250/.268/.363 in 24 games, used as a utility infielder. Isaac remained in that role in 2002 with the Dunedin Blue Jays (.250/.302/.313 in 23 games) and the Tennessee Smokies (.200/.289/.288 in 27 games).
In 2003, Iorg was let go by Toronto and signed with the Atlanta Braves organization. Assigned to the Myrtle Beach Pelicans, he hit .268/.325/.354 in 89 games as a utility man. His primary role was as backup 2B to Aaron Herr, another second-generation baseball player. In 2004, Iorg hit .274/.359/.334 in 80 games for Myrtle Beach and saw the most time of any of their first basemen, taking over there when Scott Thorman was called up. Iorg also played 12 games for the Greenville Braves, going just 2 for 27 with two walks and 10 strikeouts.
