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. 2008 season On June 17, Hernández became the thirteenth AL pitcher ever to throw an "immaculate inning" (striking out the side on exactly nine pitches). He did this versus the Florida Marlins in the 4th inning. On June 23, in his only at bat of the season, Hernández hit his first major league home run, a grand slam, off Johan Santana of the New York Mets. Hernández became the first American League pitcher to hit a grand slam since Cleveland's Steve Dunning hit one on May 11, 1971, and was the first to do so since interleague play and the DH rule began. It was also the first home run ever hit by a Mariners pitcher. Later on in the same game, Carlos Beltrán slid into Hernández as he covered home, injuring the pitcher's left ankle. He was forced to leave the ballgame and was placed on the 15-day disabled list. He finished the season with a perfect 4.000 slugging percentage. Hernández finished the season with a 9–11 record posting 3.45 ERA and 175 strikeouts. He also threw the fastest fastball of all AL starters in 2008, averaging 94.6 miles per hour. 2009 season In January, Hernández avoided arbitration and agreed to a one-year, $3.8 million deal. Hernández got off to a fast start, starting the season with a 4–0 record, only to fall cold in May, going 1–3. After a particularly sloppy loss against the Anaheim Angels, manager Don Wakamatsu publicly called him out for not "stepping up" as an ace. Hernández would go on to lose just two games during the rest of the year. On June 19 against San Diego, Hernández threw a complete game, two-hit shutout against the Padres. This was his first complete game of the season and one of the best starts of his career. His sizzling performance in June (3–0 record, 0.93 ERA, 35 strikeouts) would earn him the AL Pitcher of the Month award for June, and on July 5, 2009, Hernández was selected along with outfielder Ichiro Suzuki as the Mariners representatives in the 2009 MLB All Star
