Torres used the oversized gear when he worked the eighth inning of a 4-2 loss to the Los Angeles Dodgers on Saturday night. There was little on-field reaction.
''There really isn't that much difference between this and a regular hat,'' Torres said. ''It may not look great, but I can't feel a difference.''
Torres said he's had the cap, approved by Major League Baseball in January, for about a month. He said he tried it on while playing catch on a few occasions before finally wearing it in Saturday night's game.
Asked why he decided to wear it in a game, Torres said: ''If it can save your life, why wouldn't you? I'm not worried about how it looks if it works.''
''That's a scary thing to witness and it makes you think that could be you,'' he said.
