Twitter reacts to Serena Williams winning Sports Illustrated’s 2015 Sportsperson of the Year.

Serena Williams is Sports Illustrated’s 2015 Sportsperson of the Year, earning the distinction after winning 53 of 56 matches this year and narrowly missing the fourth Grand Slam title she needed to complete a calendar year “Serena Slam.”

Despite Williams’s dominance, social media reactions were mixed, with some people upset that American Pharoah (who ended a 37-year Triple Crown drought with his Belmont Stakes win and was the reader’s choice in SI’s Sportsperson poll) was not honored with the award.
