Nats' skipper Davey Johnson talked catching before Wednesday afternoon's game against the Miami Marlins. Wilson Ramos, the Washington Nationals' 70-year-old manager said, was probably a week away from entering the lineup as a designated hitter. "He's going through some testing today," Johnson said, "He had the measurements on [his knee] and the measurements came out pretty good. The leg is doing great. He's probably a week away from taking some DHing." The tests on the 25-year-old catcher's leg are to gauge the strength of his surgically repaired knee. Ramos had two separate procedures performed last summer when he tore the ACL and meniscus. "His strength is probably around 92-95[%]," in the right leg Johnson said. "But they do different kinds of tests and then I think [team doctor Wiemi Douoguih] is coming in on the weekend and he'll look in too. But my concern is [Ramos] is... he's doing everything and I'd like to get him some at bats." Johnson noted that Ramos continues to swing the bat well in BP, but hasn't played in a game since suffering the injury and once he does, Johnson said he'd be more comfortable that Ramos will be ready for Opening Day, "... but that all depends on the medical team," the manager added.
