On September 27, Sánchez earned his tenth win against the Cincinnati Reds, joining teammates Josh Johnson, Scott Olsen, and Ricky Nolasco in the first set of four rookie teammates in MLB history to record ten or more wins in their rookie seasons. Marlins left-hander Dontrelle Willis had a record of 12–12, so with Sánchez's tenth win, the Marlins had their first set of five pitchers with ten or more wins in franchise history. He finished his first season with the Marlins with a record of 10–3 and an ERA of 2.83 in 18 major-league games (17 starts).
