    Ryan Mattheus and Kurt Koehler were supposed to attract most of the attention on the Sac City pitching staff this spring, but the unheralded Marquez passed them to become the best junior college prospect in northern California. While Mattheus (Rockies, 19th round) and Koehler (Marlins, 17th round) developed into two of the state's best draft-and-follows in 2003, Marquez saw no action for the Panthers. A walk-on, he threw only 82-83 mph when he enrolled, so he redshirted. A year later, he was up to 90 and everything snowballed from there. He was used in a variety of roles early and eventually took over Mattheus' spot in the rotation, going 8-2, 1.46 with 62 strikeouts. He showcased a quick, easy delivery with a darting, sinking fastball that peaked at 94. He adds a good changeup and an adequate curveball.
