There’s “rampant” speculation across the industry that free agent catcher Matt Wieters will sign with the Nationals, according to ESPN’s Buster Olney (Insider required and recommended). The Nationals traded for ex-Padres starting catcher Derek Norris earlier this month, but Roch Kubatko of MASNsports.com then noted that they could sign Wieters and flip Norris elsewhere. Of course, it’s worth pointing out that Wieters’ agent, Scott Boras, is close with Nats owner Ted Lerner and president/general manager Mike Rizzo. The 30-year-old Wieters has spent his entire career in nearby Baltimore, but it may have replaced him Friday with the signing of Welington Castillo.
