If you’re like me and slept late, you woke up to some good news from Florida. Joba Chamberlain made a rehab start and his final line was: 1 IP, 0 H, 1 R, 0 ER, 0 BB, 2 K.

And he hit 97 mph on the gun.

Does anyone else want to do cartwheels right now? I’m afraid to get too excited because setbacks are possible but this is just unbelievable to me. When Chamberlain’s ankle injury first came to light back in March, it was hard to imagine seeing him pitch again and now he could be back in the Bronx as early as next month.

And then there’s Mo: This morning there was a report saying that a 2012 return could be possible for Mariano Rivera. I know, I know, calm down.

Dr. Keith Pyne recently told the New York Post that the 42-year-old is “working his butt off” and “itching to get back.”

Though the decision will belong to the Yankees, Rivera and renowned surgeon Dr. David Altchek, Pyne said the one-month delay before surgery may have actually helped the timetable for baseball’s saves leader.

“This is a very detailed guy and he did everything right (pre-surgery),” Pyne told the Post. “He strengthened, he got range of motion. He was very functional before surgery. I don’t want to put a percentage on it, but he reduced recovery time by a lot.”

And then the letdown:

Pyne gushed over the hard-working Rivera, who he called “special” and “in the top 10 percent of athletes I have worked with.”

“He’s got everything it takes to accomplish that,” Pyne said of Rivera returning in 2012. “If I was putting money on it, I would put my money on Mo.”

The doctor did admit to the paper, “Right now, he’s shut down until next year.”

Emphasis on “right now.” The five-time World Series champion may have a fighting chance to make his mark this October after all.

Why do you have to tease us like this?

Could you imagine if Rivera was back in the Bronx pitching in the playoffs? I think I may cry.
