Because some pitchers just don't start forever
At the center of the Reading Fightin Phils rotation are two pitching prospects, one homegrown and one a trade acquisition, who are both incredibly similar and yet totally different prospects. I speak not of Ben Lively - the guy leading the Reading rotation in most statistical categories - but instead of fellow righties Nick Pivetta and Ricardo Pinto.
Pivetta is a 6'3" 23-year-old Canadian that the Nationals took in the fourth round of the 2013 draft. The Phillies got him (and a lot of good feelings) in the trade that sent Jonathan Papelbon to Washington last July.
