San Diego ? The San Diego Padres acquired Todd Walker from the Chicago Cubs on Monday to help out at third base, which has been a weak link offensively for the defending NL West champions.

The Padres also got $350,000 in the deal and sent minor league right-hander Jose Ceda to the Cubs.

Mark Bellhorn is still expected to get playing time at third base for the Padres, who released slumping Vinny Castilla on July 19. Geoff Blum, who also has filled in at third, will return to a utility role.
