The Phillies will give nine of their marquee farm-system players a look during spring training.
The prospects, all with familiar names, were formally invited Wednesday to Clearwater. They include:
n Mark Appel, the No. 1 overall pick in the 2013 draft, a right-handed pitcher acquired from Houston in the trade for Ken Giles. He was 10-3 in the minors last season.
n J.P. Crawford, heralded as the Phils' top prospect. In Clearwater and Reading last season, the shortstop hit .288 with a .414 slugging percentage.
n Zach Eflin, a right-handed pitcher who was 8-6 with a 3.69 ERA in Reading. He arrived through Los Angeles in the trade for Jimmy Rollins.
n Andrew Knapp, a switch-hitting catcher who had 13 minor-league homers last year.
n Gabriel Lino, a 22-year-old catcher acquired in 2012 from Baltimore in a trade involving Jim Thome.
n Logan Moore, a catcher who hit .253 last season.
n Brock Stassi, whose .300 average, 32 doubles and 15 home runs helped him become the Eastern League MVP in 2015.
n Jake Thompson, a right-handed pitcher who went 5-1 with a 1.80 ERA in seven starts after arriving from Texas in the swap for Cole Hamels.
n Nick Williams, 22, a power-hitting outfielder also acquired in the Hamels trade. He had a .491 minor-league slugging percentage last summer.
