Atlanta Braves CEO Terry McGuirk didn't hesitate when the front office called to request an increase in payroll to sign Ervin Santana earlier this week.

Kris Medlen is likely headed for Tommy John surgery, creating a spot in the starting rotation.

"We're not in a rebuilding mode, we're in a winning mode," McGuirk said. "We're standing around right now in this clubhouse with a bunch of winners around us. We think the time is now. We've always been willing to add to the payroll and the substance of this club."
