A batting cage is set up in the backyard of Jayson Werth's Northern Virginia manse, a cage much like one in his own yard during his Springfield, Ill., youth. If Werth's two sons, ages 10 and 7, feel so inclined, they can duck inside the netting and take some hacks - and maybe become the fourth generation in the family to play in the major leagues. "It'll be up to them just like it was up to me," the Washington Nationals' right fielder said after Tuesday's workout at Space Coast Stadium. "My 10-year-old wants to play, loves the game. The 7-year-old, he's coming around. If that's what they want to do, great. If they want to do something else, I'm fine with that, too."
