Rotoworld thinks we have a good rotation:
The 33-year-old southpaw, helped by the tutelage of pitching coach Ray Searage, posted a 1.85 ERA, 1.03 WHIP and 69/13 K/BB ratio over 63 1/3 innings down the stretch after a mid-season trade to the Pirates. Happ returns to Toronto where he previously pitched from 2012-2014. He adds another quality arm to the back of what is becoming a deep and talented starting rotation.
