Playing in his first match of the Apex Wisconsin Open, Immonen was upset by rising young American Sam Henderson in a shootout. After Henderson won the first set, 4-2, the former two-time United States Open 9-Ball champion stormed back to win the second set, 4-1, and force a shootout. Henderson held the steadier hand in the extra-frame spot shot contest, pocketing three balls while Immonen could only manage two.
