Former National League Rookie of the Year Dontrelle Willis made his Giants organization debut on Saturday night in Fresno.
The 32-year-old was activated by the Grizzlies Saturday afternoon and faced one batter against the Las Vegas 51's, getting Taylor Teagarden to ground out to end the top of the 10th inning.
