After surgery to repair the damage, Dahl opted to have his spleen removed, rather than waiting for it to heal, in order to return to baseball with less recovery time.

After he batted .278 with 13 home runs, 45 RBIs, and 16 stolen bases for Hartford, the Rockies promoted Dahl to the Albuquerque Isotopes of the Triple–A Pacific Coast League.
