Holy Sidd Finch! Minnesota Twins Sign Unknown with 100-Mph Fastball: The Minnesota Twins have signed a 24-year-old who throws a 100-mph fastball but has never been drafted. Brandon Poulson of the Healdsburg Prune Packers, a collegiate summer league team, got a $250,000 deal. He's a 6-foot-6 right-hander and fitness freak who was timed at a 6.6-second 60-yard dash in his socks and has a 40-inch vertical leap. "He's a physical specimen. He's got the best pure arm strength I've ever seen," said Twins scout Elliott Strankman.
