Designated hitter David Ortiz, who returned to the lineup Friday night after missing 35 games because of a strained right Achilles’ tendon, was again out for the Red Sox’ 10-9 extra-inning loss to Kansas City on Saturday night.

Manager Bobby Valentine said Ortiz “was a little sore’’ after going 2 for 4 with a double and two RBIs in Friday night’s 4-3 victory over Kansas City.
