Third baseman Will Middlebrooks tripped Allen Craig for a game-ending obstruction call on Jon Jay's ninth-inning grounder, giving the St. Louis Cardinals a bizarre 5-4 win over the Boston Red Sox on Saturday night and a 2-1 World Series lead.

Boston had tied the score with two runs in the eighth.

Craig pinch hit and lined Koji Uehara's first offering down the left-field line for a double that put runners on second and third.
