The Phillies have designated Scott Mathieson for assignment, according to Todd Zolecki of MLB.com (via Twitter). The right-hander wasn' t out of options, tweets Matt Gelb of the Philadelphia Inquirer. The move leaves 39 players on the club's 40-man roster.
Mathieson, 27, saw action in just four big league games this season. In 18 Triple-A relief appearances and six starts this year, Mathieson turned in a 2.92 ERA with 10.5 K/9 and 4.8 BB/9.
