Colton Murray made his major league debut with the Phillies last season, but will have to wait to make his 2016 debut with the club. The Phillies optioned the right-hander to Triple-A Lehigh Valley Monday, where he'll likely be a major piece of the IronPigs bullpen. Infielder Taylor Featherston was also optioned to Lehigh Valley.
In a somewhat surprising move, the Phillies released right-handed reliever Ryan O'Sullivan, who was 2-3 with a 2.39 ERA in 36 relief appearances with Double-A Reading last season. O'Sullivan, 25, also saved four games for the Fightins last season in limited opportunities to close. O'Sullivan is the younger brother of former Phillies pitcher Sean O'Sullivan, who pitched in 16 games - 15 of them starts - with the Phillies over the past two seasons, posting a 6.13 ERA. The elder O'Sullivan signed a minor league deal with the Boston Red Sox over the Winter.
Also released Monday was the nephew of former Phillies general manager Ruben Amaro, Jr. Andrew Amaro was drafted by the Phillies in the 35th round of last year's draft and hit .218 in 16 games with Williamsport and 4 with Lakewood. The 22-year old played primarily in right field, but had one game at first base.
Murray had a 5.87 ERA in eight games with the Phillies last season, and had a combined 2.67 ERA in 52 games between Reading and Lehigh Valley.
Featherston, 26, also made his MLB debut last season with the Los Angeles Angels, playing in 101 games, batting .162 as a utility infielder for the Angels. The Phillies acquired him last month for cash or a player to be named later in a deal with the Angels.
The Phillies spring training roster now stands at 49 players in camp.
