Red Sox right-hander Clay Buchholz hopes to throw off a mound next week. For the second straight day, the righty played catch on Tuesday, throwing 50 pitches at 90 feet. "Effort level was a little bit higher today. It was good to test it out. Everything felt good, though," Buchholz said. He is recovering from a stress fracture in his lower back and hasn't pitched since June 16. "If everything goes right -- and I think I'm doing two days on, one day off -- if there's enough days, that's what we're going to do hopefully for sure while we're home, I'll be able to put some spikes on and get off a mound and see how it feels," Buchholz said.
