Wilkin Ramirez, back from concussion, to fill Twins' open roster spot | 1500 ESPN Twin Cities ? Minnesota Sports News & Opinion (Twins, Vikings, Wolves, Wild, Gophers) | Sportswire: Minnesota Twins Outfielder Wilkin Ramirez finally returns from a concussion. This is his shot to try and stay on the 25 man roster and hold out until September, when his roster spot is probably safe. Recall when Morneau and Span returned from their concussions...frankly, they couldn't hit. Let's hope Ramirez can get cracking and lift that .244 batting average up. If he doesn't, Darin Mastroianni could be talking his spot back.
