"The Nationals lost hard-throwing reliever Cole Kimball today when the Toronto Blue Jays claimed him off of waivers. Kimball, 26, made his major league debut this year for the Nationals and looked like one of their most promising relief pitchers until he tore the labrum in his right shoulder. Kimball will be able to pitch again in the majors by the all-star break at the earliest.

The Nationals were trying to sneak Kimball through waivers in order to open space on their 40-man roster. By Friday, the Nationals will need to add several minor leaguers to the roster in order to keep from potentially losing them in the Rule 5 draft. "It's a bummer," one Nationals official said. "That's the risk you take.""
