I don't think so. This seems to be their year. I don't know how many, but a fair number of their games have been come from behind. They are never out of a game. They have a potent offense, great starting & bullpen pitchers & solid defense. Their 8th-hole hitter, Yasiel Puig, is hitting great - gong the opposite way & taking walks. He finally seems to have grown up. And they are doing this while Kershaw is on the DL. 50 game over .500 is no fluke.
Since 1900 there were nine Major League teams that have finished a season with a .700 winning percentage or higher. Only five of them actually won the World Series the same year. The last one to reach the .700 mark was the 2001 Mariners, who did lose in the postseason.
