Lively was designated for assignment by the Phillies on Monday, Todd Zolecki of MLB.com reports.
The Phillies needed to free up a roster spot for Jerad Eickhoff, who was activated from the 60-day disabled list Monday, and Lively was the corresponding roster casualty. The 26-year-old struggled to a 6.85 ERA across 23.2 innings with the Phillies this season.
