He joined the Mariners' Triple-A affiliate, which was now the Tacoma Rainiers. In 33 games (one start) for Tacoma, he had a 1–2 record, four saves, a 2.95 ERA, 21 strikeouts, nine walks, and 33 hits allowed in innings. On August 15, the Mariners purchased his contract from Tacoma, sending Bill Krueger to the minor leagues to make room for him.
