New York Yankees

Marquez attended Sacramento City College before being chosen by the New York Yankees in the supplemental round as the 41st overall pick of 2004 MLB draft. Marquez was a compensation pick for losing David Wells to the San Diego Padres.

In 2005, Marquez played for the Single-A Charleston RiverDogs. Making a team leading 27 starts, he went 9-13 with an ERA of 3.42. Marquez was second on the team to Chase Wright in wins (9), innings pitched (139+23), and strikeouts (107).

In 2007, Marquez played for the Double-A Trenton Thunder and was an Eastern League midseason All-Star for the team that year. Marquez went 15-9 with a 3.65 ERA for the Thunder. He led the league with 15 wins, was tied with 27 starts, was tied for second in innings pitched (155+13), tied for third in complete games (2), and was tenth in ERA (3.65).

On November 20, 2007, the New York Yankees purchased Marquez's contract, protecting him from the Rule 5 draft.
