Phillies pitching coach Rich Dubee said Tuesday that he has some "mild concern" about Antonio Bastardo's lack of velocity this spring. Bastardo hasn't shown any signs of improvement after taking a week off due to forearm tightness, something the Phillies said was caused by dehydration. "I'm not seeing velocity like I should be seeing," said Dubee. "But at the same time, I think we've got that disease going through our camp where we've got a lot of dead arms right now. That happens a lot." Bastardo topped out at 91 mph with his fastball during an appearance on Sunday after averaging 92.5 mph with his heater last season. The Phillies have maintained that there isn't any structural damage with his forearm, so the cause for the diminished velocity remains a mystery.
