Biddle, the Germantown Friends graduate and former first-round pick, is likely ticketed for triple-A Lehigh Valley in April. Manager Ryne Sandberg said last month Biddle is a "back-burner type of possibility" for the 2014 rotation. The 22-year-old lefty posted a 3.64 ERA with 10 strikeouts per nine innings at double-A Reading in 2013.
The Phillies also invited righthander Ken Giles, lefthander Mario Hollands, and catcher Sebastian Valle to spring training. Giles, 23, is an intriguing arm. He throws 100 m.p.h. and impressed during Arizona Fall League action.
Morandini moves up
The Phillies promoted Mickey Morandini to bench coach at triple-A Lehigh Valley. Morandini, 47, spent the last three seasons as a manager at the single-A level. The former second baseman was a candidate to serve as the Phillies' assistant hitting coach until John Mizerock was promoted.
Veteran coach Greg Legg will replace Morandini at single-A Lakewood. Ramon Henderson will manage single-A Clearwater. He was the Phillies' bullpen coach from 1998 to 2008 before he was fired for substance abuse.
Chris Truby, the manager at single-A Clearwater last season, will be the organization's infield coordinator in 2014. Doug Mansolino was promoted to field coordinator.
