The Phillies announced that they claimed Mauricio Robles off of waivers from the Mariners. Seattle had designated the left-hander for assignment six days ago.
Robles, 23, posted a 5.78 ERA with 8.7 K/9 and 7.9 BB/9 in 43 total games in the upper minors this past season. In parts of seven minor league seasons he has a 4.15 ERA with 9.4 K/9 and 5.3 BB/9. The Phillies already have left-handed relievers such as Antonio Bastardo, Jeremy Horst and Raul Valdes on their 40-man roster.
