MIAMI (AP) — Colorado's Jamie Moyer has now pitched in 50 Major League ballparks.

Moyer started for the Rockies in Miami on Monday night, making his debut at the newly opened Marlins Park. The 49-year-old lefty has played in more parks than any other major-league player going back to at least 1921. Rudy Seanez, whose last big-league appearance was in 2008, appeared in 47 ballparks.

Last month, Moyer became the oldest pitcher to win a major league game. He has pitched against 11 current big-league managers, including Miami's Ozzie Guillen, who went 4 for 22 against Moyer in his career.

Moyer first pitched in the majors in 1986. He was 8-2 at the Marlins' former home, Sun Life Stadium.
