Alex Rodriguez
Baseball hasn’t provided the same kind of international star power that tennis or soccer has accomplished, but it’s worth noting one of the ex-players who has made real strides as social media guru. Alex Rodriguez, never really considered anything more than high-priced talent during his playing days, has turned himself into a powerhouse brand, with ventures that go beyond the field as well. Rodriguez’s television spots as a baseball analyst for ESPN and Fox—and even more digital-based enterprises such as The Corp with Barstool Sports’ Dan Katz—have increased his following, with Mr. Jennifer Lopez nearing five million followers across Twitter and Instagram.
