Stephen Strasburg
Bannister spent the winter rehabilitating his shoulder and returned to what would be his last MLB season. His ineffectiveness was obvious, and he struggled with giving up home runs and pitching deep into games. On June 23, 2010, Bannister and the Royals handed Washington Nationals phenom Stephen Strasburg his first career loss in a 1–0 victory in Washington. His season finished with a miserable loss at Cincinnati, a minor league rehab stint, and a loss to the Minnesota Twins.
