Yes, you're reading that right.
Team spokesman Brian Bartow said Holliday was taken into a dark room and trainers put a light by his ear, trying to lure the insect out. That didn't work, so they used a utensil to get the moth, which was still alive, out of Holliday's ear.
The Cardinals lost to the Dodgers tonight. Not sure if Holliday would have had any impact, but the Brewers might have to erect a statue to that moth if they go onto win the NL Central. Or at least name a hot dog after it.
