Bret Boone has joined his brother Aaron and father Bob in Washington, according to the Associated Press. Boone, who retired in 2005, announced on Monday that he is going to attempt a comeback with the Nationals this season. "My dad being here, and Aaron being here -- if I was going to extend my career a year or two, I think it would be pretty cool playing with him," Boone told the AP. "At this stage, I didn't have 30 teams banging my door down. It's an opportunity, and I'm very appreciative of it. Everybody doesn't get to do this."
