August 18, he relieved Martínez in the fourth inning after a rain delay, pitching six scoreless innings to earn his 11th win of the season. A similar situation occurred on August 28, as Moyer again relieved Martínez in the third inning after a rain delay. He pitched 4 in relief, giving up one earned run, and picked up his 12th win of the season. Moyer tore three muscles in his groin and lower abdomen while pitching against the Houston Astros on September 29. He missed the rest of the regular season, and was not on the Phillies' postseason roster. 2010 When asked about retiring after the expiration of his Phillies contract at the end of 2010, Moyer said, "You know, I'm going to leave that as an open-ended question because I don't know how to answer that. It could be (my last season). It potentially could be. But so could have last year. So could have two years ago, so could have five years ago." After the retirement of Ken Griffey Jr. in early 2010, Moyer and Omar Vizquel were the last two active players in MLB who played in the 1980s. On April 10, at age 47, Moyer became the sixth-oldest pitcher to appear in a game and the eighth major league pitcher to start a game in four different decades. Moyer pitched six innings and earned his 259th career victory. On May 7, Moyer became the oldest player in Major League Baseball history (47 years, 170 days) to pitch a shutout, blanking the Braves on two hits, striking out five batters and walking none. Moyer also became the only MLB pitcher to throw a shutout in four different decades (1980s, 1990s, 2000s, and 2010s). On June 5, Moyer became the third MLB pitcher to win 100 games after turning 40 years old, defeating the San Diego Padres, 6–2, using just 98 pitches to accomplish the feat. It was also his second complete game of the season. On June 16, Moyer became the oldest pitcher to ever defeat the New York Yankees. Moyer beat the Yankees at 47 years, 210 days. On June 27, he surrendered a home run to Vernon Wells of the Toronto Blue Jays to become the all-time major league leader in home runs allowed (506), passing Robin Roberts. On July 20, Moyer left a start against the St. Louis Cardinals due to an elbow strain
