The Yankees released J.C. Romero at his request, according to Ken Rosenthal of FOX Sports (on Twitter). The 35-year-old has a 2.21 ERA with 7.1 K/9 and 3.1 BB/9 in 17 minor league appearances this year.
It's been a busy year for the left-hander, who started the season in Philadelphia, where he posted a 3.86 ERA with more walks than strikeouts in 16 1/3 innings. The Phillies released him in June and he signed with the Nationals within a week. The Yankees signed him in July, soon after the Nationals released him.
