The Yankees added two starting pitchers in the offseason, acquiring James Paxton in a trade with Seattle and then re-signing J.A. Happ after his mid-season trade to New York last summer.   This week in a new episode of 30 With Murti, Sweeny chats with the two newest members of the Yankees rotation.  You'll hear Happ talk about about his evolution as a pitcher and what key concept helped him turn in his best year yet at age 35.  And you'll hear Paxton talk about his drive for perfection and how he's learned to focus and channel that drive to become a better pitcher.
