He received a similar reaction on social media, where even some of the Giants’ biggest rivals tipped their caps:

Congratulations to Matt Cain, who announced his retirement earlier today, on a decorated career. Best of luck in all your future endeavors! pic.twitter.com/kG9UUBB7k8

Easy for them to say, as they never have to face “The Horse” again. Cain beat the Colorado Rockies 17 times and the Arizona Diamondbacks 15 times, easily more than his third-most victimized team (eight wins vs. the San Diego Padres).
Among the others to congratulate Cain were actor and noted Giants’ fan Colin Hanks and a swath of former and current teammates:
