Wander Franco, the 22-year-old All-Star shortstop for the Tampa Bay Rays, was placed on administrative leave indefinitely by Major League Baseball while authorities in the Dominican Republic investigate allegations of an inappropriate relationship with a minor. The investigation was prompted by allegations of an inappropriate relationship leveled against Franco on social media. Franco was held out of the Rays’ lineup on August 13 in what the Rays manager said was a day off, then missed a six-game West Coast trip while on the restricted list. The Rays issued a statement supporting the administrative leave decision. Franco will continue to be paid and accrue service time while on leave. The investigation is expected to continue well beyond the end of the season, and prosecutors hope to talk to Franco in the coming weeks, which would make a return this season unlikely in any circumstance.
