Former San Francisco Giants pitcher Terry Mulholland and former New York Yankees pitcher Orlando Hernandez each once tossed their gloves to first basemen to get outs.
It’s not the first time Guerrero has had issues with his glove. He had two throws go through his webbing last season, including one that led to a run for Seattle in a 6-5 loss to the Mariners in July.
