Upon his return, Hernández initially battled to regain the form he had flashed in those first two starts of the year. Hernández finished the season with a 14–7 record. His victory over the New York Yankees on September 3, in his first appearance at Yankee Stadium, stopped a nine-game Mariner losing streak, but was not enough to keep the team from falling out of playoff contention. His 3.92 ERA for the season was the best among the team's starters, and he again led the Mariners in strikeouts with 165. He again threw the fastest fastball of all major league starters in 2007, averaging 95.6 miles per hour.
