Dan O’Dowd and the Rockies had the ninth overall pick in the 2002 draft. They decided to go with a left-handed pitcher Jeff Francis. In his 11 year career, he had a 72-82 record with a 4.97 ERA (93 ERA+) and a 9.6 WAR.
While not great, his career year was in 2007 and was big reason why the Rockies made the World Series. He had an ERA of 2.13 in the NLDS and NLCS but he did not pitch well in the World Series.
