Mike Vasil isn’t used to this. It’s only been a couple of weeks, but he usually doesn’t get the luxury of spending an elongated period of time during the summer at his home in Wellesley. Fresh off his junior season at the University of Virginia, the highly-touted, hard-throwing right-hander expects his summers to take place elsewhere in the future. The exact location is unknown at the moment, but Vasil will gain clarity on his next destination when the three-day MLB draft commences on Sunday.
