Clayton Kershaw lost for the first time since May, allowing the go-ahead run when Max Muncy misplayed a potential inning-ending double-play grounder in a 2-1 defeat to the San Francisco Giants on Saturday night that left the Los Angeles Dodgers one win shy of 100 going into their season finale. Kershaw (13-5), a 35-year-old three-time Cy Young Award winner, had been 7-0 with a 1.96 ERA in 13 starts since a May 21 loss at St. Louis. Facing the Giants for the 59th time, he allowed a third-inning homer to Tyler Fitzgerald and gave up two runs and five hits in 5 1/3 innings.
