Cardinals general manager John Mozeliak considered Friday Adam Wainwright's spring training results, how the righthander made every start and showed sharpness after a year of rehab, and came to an unexpected conclusion.

"It's almost to the point where I'm nervous," Mozeliak said.

Both the GM and the pitcher acknowledged there will be "butterflies" and "nervous excitement" leading into this afternoon's start against Milwaukee, Wainwright's first since his final game and 20th win of the 2010 season. There will also be precaution. While resisting any inference that Wainwright will be on a pitch count or innings restriction as he makes his way back from Tommy John surgery, the Cardinals will be closely monitoring his work throughout this season, and especially early on.

"He's a tremendous talent and now that he's back to where he is I think (today) is just going to be a taste of what he's capable of doing," Mozeliak said. "I think (with) most people a year out of Tommy John you have to be cautious. In this case, there's no reason to put too demanding of a role on him at this time. We have to be smart about it."

Wainwright threw 75 pitches in his final appearance of the spring, a live batting practice session Monday. He said it's unlikely he would jump from there to 100 pitches in today's start. He stressed that not all pitchers are created equal and that he expects the team to be careful with him in strenuous innings and might not let him grind out of jams the way he did during his 20-win year.
