Assuming he’s still on the team then, Sox pitcher Josh Beckett will host his annual Beckett Bowl at Jillian’s Lucky Strike Lanes Aug. 20. The event, which typically attracts a few celebs and several of Beckett’s teammates, is a fund-raiser for Boston Children’s Hospital. This year, the bowling tourney will be followed by a concert at the House of Blues featuring country musicians Pat Green, Kevin Fowler, Randy Rogers, Stoney LaRue , and others.
