"It makes sense," Kelly said, according to Rob Bradford of WEEI. "It's a secure zone, but it was the first time in my life I have felt insecure. I was insecure in the secure zone."
Kelly said a big problem was that the hotel had a busy golf course at the location.
"It wasn't called the bubble," Kelly said. "It was called the secure zone, for people who don't know. We were at a nice hotel, a beautiful hotel in Las Colinas, and there is a golf course there and I happened to have a room, a villa, on the 18th green, which is pretty crazy because it's a secure zone. But my room, I would say, is no more than 20 yards from the green, it's still open to the public.
"So, it's a bubble except golfers are hitting golf balls next to my window and then crossing the secure zone tape line."
The 32-year-old reliever admitted that more members of the team could've gotten infected.
"Yeah, we got lucky, I feel like," Kelly added. "If we weren't aware as players to try and stay away from getting it and we let our guard down, I'm sure it could have been more than just one."
