Monday the All-Stars met with the media and then took to Target Field for batting practice.
St. Louis manager Mike Matheny is the National League skipper, and named his ace Adam Wainwright to start the game.
Wainwright is 12-4 with a 1.83 earned run average.
He also leads the National League with three complete games.
Back in late May, Wainwright threw his first career one hitter against the Diamondbacks.
Wainwright's first pitch will be to the retiring Yankee Derek Jeter, those two squaring off for the first time ever.
"Aside from having the ability to win two World Series with the St. Louis Cardinals, this has to be one of the highlights of my baseball career to this point," said Adam Wainwright. "Just one of the coolest things I can say I did was to start a big league All-Star game. I'm just incredibly happy and fortunate to be placed in this situation. I can't wait to go out and hopefully lead our National League squad to a victory."
