BALTIMORE—Maybe it's the natural development of a young pitcher's body, or maybe it's the extra innings he's thrown. Whatever the reason, Ryan Keefer's velocity increased from the upper 80s to the mid-90s during the 2005 season. When your velocity goes up, so does your stock. Keefer went 7-3, 3.20 in 84 innings at Double-A Bowie last year. Moved into a set-up role, he posted a 0.42 ERA over a 13-game span. In his last nine outings covering 11 innings, Keefer permitted only one earned run.
