Players remain on the bereavement list for a minimum of three days to a maximum of seven days.
Guerra's father suffered a heart attack Friday morning in Nuevo Laredo, a town on the border with Texas near the Rio Grande River, and was scheduled for Saturday surgery.
Guerra returned to the Dodgers on July 5 after missing a month with right knee surgery. He spent Friday figuring out travel and passport details, which is why manager Don Mattingly had mixed feelings about asking Guerra to pitch the seventh inning of a 2-1 win over the Padres after the Dodgers had taken a one-run lead.
"I was a little concerned, honestly, when he gives up that hit," Mattingly said. "I got Josh [Lindblom] up right away."
Wall, a 25-year-old right-hander with a power arm who is ranked No. 16 among the Dodgers' top prospects, has 18 saves but a 5.68 ERA at Albuquerque. He was a second-round pick in the 2005 Draft.
"To me, he's a guy on the move," Mattingly said. "As his confidence grows, he has a chance to be pretty good."
