The Padres optioned pitcher Jesse Hahn to Triple-A El Paso Saturday and recalled infielder Jace Peterson.
The team brought an extra infielder into the fold while Tommy Medica deals with an injury. Hahn, who won for the fifth time in his last six starts Friday, is expected to return to the team after the All-Star break. He owns a 2.21 ERA and 47:16 K:BB ratio in 40 2/3 innings.
