Baseball keeps Mookie Betts plenty busy, but he’s got a lot of other things going on, too. The ad plays up baseball’s reputation for superstition, though in reality, Betts admits, “I’m not a superstitious guy.” I was young in the sport, and when you’re playing the Yankees, you knew things were going to be heated. And then this baseball necklace, there was a kid in maybe 2017 or ’18, and he gave me a necklace for a signed ball. $29.99 Betts’ own fan-gifted necklace inspired All-Star Pieces, a line of similar necklaces with part of the proceeds supporting youth sports.
