Joba Chamberlain is just dying to get a look at the radar-gun readings. No one will let him see them.

"I don't know if it's a good thing or a bad thing," the righthander told the Daily News Wednesday after throwing on flat ground with the Yanks' pitching guru, Billy Connors. "I know how it feels. It's coming out good. It feels great. Velocity-wise, I couldn't tell you how hard."

The only hint that he's throwing major league hard are the looks on the faces of the coaches and catcher who have been working with him at the team's minor league complex the past several weeks — and he likes their reaction.
