Dodgers right-hander Yoshinobu Yamamoto lasted one inning and was yanked after the San Diego Padres batted around to take a 5-1 lead on Thursday in an extension of the high-priced pitcher's spring training struggles.

Yamamoto signed a $325 million contract with the Dodgers after fielding offers from the Philadelphia Phillies and both New York teams. Early returns on the 12-year deal are unsettling.
