Zach Wheeler has a 140 ERA+ in his five years with the Phillies. Since WWII, only three starting pitchers have finished their careers with at least a 140 ERA+: Pedro Martinez, Roger Clemens, and Brandon Webb (who only pitched for six seasons plus one game). There are also two active pitchers above 140, Clayton Kershaw and Jacob deGrom. Chris Sale is at 139.
Wheeler won't finish his career above 140 since he was more ordinary with the Mets. But it shows how high a level he's pitched at for the Phils.
