Marks was one of two starting pitchers named to the 22-player team selected for performance during the six-week fall season as well as Major League projectability.
Pitching for the Surprise Saguaros, Marks led the league with five victories, going 5-1 with a 2.59 ERA in seven starts. In 24 1/3 innings, he had 22 strikeouts and gave up 24 hits and five walks. He held left-handed batters to a .160 average.
He spent most of this season with Double-A Northwest Arkansas, posting a 3-5 record and a 3.80 ERA in 17 starts. His season was interrupted by an injury -- a comebacker hit him in the face and fractured his right orbital bone -- which kept him out of 42 games. While rehabbing, he pitched two games for Surprise in rookie ball and finished his season with one rocky start for Triple-A Omaha.
Marks, 24, was drafted out of the University of Louisville by the Athletics in 2009 and was traded to the Royals with pitcher Vin Mazzaro for outfielder David DeJesus after the 2010 season. Marks is on the Royals' Major League roster.
