Third baseman Mike Lowell says his superstitions are minor. ‘‘I like to take four warmup swings in the on-deck circle. Not five, not three. I think I did that in high school one day and I wound up getting four hits that day and I think I’ve done it ever since. Oh, and I never chew gum hitting. Ever. Cause I struck out while chewing gum when I was 8 years old. I had to blame it on something.’’
