If Joba Chamberlain's debut as a Yankee starter didn't go that well last night, Joe Scarborough wasted no time this morning in demonstrating that, after a stint on the DL, he still has his stuff. Within minutes of reassuming his host's role, Scarborough unleashed a high hard one in the direction of Chris Matthews's chin.

Scarborough, back from an extended leave spent with his wife who's experiencing a difficult pregnancy, reported that the medical situation seems to have stabilized. Readers will surely join in wishing Joe and his family well.

The opening segment was, naturally, devoted to a discussion of Barack Obama's clinching of the Dem nomination, and to Hillary Clinton's less-than-gracious speech in which she declined to withdraw from the race and pointedly kept her options open. Which in turn led Scarborough to suggest that, at the beginning of Obama's campaign, there were only three true believers.

JOE SCARBOROUGH: It seems to me that the Clintons have very little respect for Barack Obama. This was his night. An historic night. A night that nobody believed—but perhaps Barack Obama, Michelle Obama, and Chris Matthews—this was a night that very few people believed would ever happen. It happened. And on that night, she's sticking a sharp stick in his eye, saying listen: you either make me Vice-President, or you put me on the Supreme Court if that's what I want, or you play with me, or else . . . this is going to get really ugly.

Ouch.
