On the same day of O'Flaherty's debut, the Seattle Times reported that his "big-league visit was too short to qualify as a cup of coffee". The night before he had flown in from Triple-A Tacoma in order to replace a seemingly injured Rafael Soriano. When O'Flaherty arrived, Soriano convinced coaches he was healthy enough to remain on the Mariners' roster, so O'Flaherty was sidelined out of uniform for the rest of the night. The next day, however, infielder Greg Dobbs was returned to Triple-A, allowing O'Flaherty to pitch his first major league game.
