Lively was optioned to minor league camp Friday.
Lively was in the conversation for a call-up near the end of last season, but the Phillies decided to keep him at Triple-A. Although he struggled to a 6.97 ERA in 10.1 innings this spring, the 25-year-old posted a combined 2.95 ERA across 170.2 innings between Double-A Reading and Triple-A Lehigh Valley in 2016. He'll head back to Triple-A to start the season, and if he continues to pitch well there, he could earn a promotion sometime in 2017.
