Mark Appel, a former No. 1 overall pick, was designated for assignment by the Philadelphia Phillies on Monday.
The Phillies now have seven days to either trade him or place him on irrevocable waivers.
Appel has yet to pitch in the majors in five seasons at multiple levels. Overall, he is 24-18 with a 5.06 ERA in 375⅓ innings pitched over 81 games (78 starts).
Last season, he finished 5-4 with a 5.27 ERA in 84 innings.
The move was made as the Phillies added right-handers Seranthony Dominguez, Franklyn Kilome, Jose Taveras and left-hander Ranger Suarez to their 40-man roster.
By adding the pitchers to their 40-man roster, the Phillies protect them from being selected by another team in next month's Rule 5 draft. The deadline to set rosters before the draft is Monday at 8 p.m. ET.
In addition to Appel, right-hander Alberto Tirado also was designated for assignment. Left-hander Elniery Garcia was outrighted by the team.
