Phillies pitching prospect Adam Morgan will be called up to make his major league debut on Sunday.

He will replace Jerome Williams who was placed on the 15-day disabled list with a strained left hamstring.

"Once upon a time he was a great looking propsect with a great arm," ESPN.com senior baseball writer Jayson Stark said on the Sports Bash.

Morgan is an interesting name, now 25, he used to be a decent prospect for the Phils but fell off the radar after being plagued by shoulder issues the last couple years. He underwent surgery last January to repair a tear in his left rotator cuff and wound up missing the entire 2014 season.

"He hurt his shoulder and has not been the same and hasn't thrown well," Stark explained. "This will be an opportunity to see how far he's come back."

A third round selection from the 2011 draft, Morgan was pitching for Lehigh Valley with a 4.74 ERA and just 33 strikeouts over 68 1/3 innings.
