Xander Bogaerts is not in the Padres’ starting lineup for Sunday’s showdown against the Marlins in Miami.

The 33-year-old infielder is mired in an extended slump at the plate, so giving him a day or two off to clear his head wouldn’t be the worst idea in the world. Sung-Mun Song will start in his place at shortstop and will bat ninth for the Padres against Janson Junk and the Marlins on Sunday afternoon.
