Case in point: the Oakland Athletics‘ crosstown rivals, the San Francisco Giants, have won three of their last 21 series since the All-Star Game. They still have the worst record among all MLB teams since the All-Star break, going 20-35 (a 0.364 win percentage).
To the chagrin of Giants fans, they may not make the playoffs at all this year after having had the best first-half record in baseball. The San Jose Sharks and Golden State Warriors both lost in the finals for their respective sports, with the Warriors having one of the wildest playoff meltdowns of all time.
