Phillies' Zack Wheeler: Agrees to extension with Phillies

Wheeler signed a three-year, $126 million contract extension with the Phillies on Monday, Buster Olney of ESPN reports.

Wheeler had been in line to reach free agency after the upcoming season, but now he'll remain in Philadelphia for a while longer. The average annual value of the deal is a Phillies record and also the largest-ever AAV for a contract extension. The veteran right-hander has collected a 3.06 ERA, 1.06 WHIP and 21.3 K-BB% across 101 starts during his time with the Phillies and will turn 34 in May.
