Input: Question: Was Vida blue older than Kent Mercker when he threw his no-hitter? Passage:Vida Blue, Kent Mercker, Kevin Millwood, and Cole Hamels are the only pitchers to start both a complete game no-hitter and a combined no-hitter. Vida Blue no-hit the Minnesota Twins on September 21, 1970, while pitching for the Oakland Athletics. He combined with Glenn Abbott, Paul Lindblad, and Rollie Fingers to no-hit the California Angels on September 28, 1975. While with the Atlanta Braves in 1991, Mercker, Mark Wohlers and Alejandro Peña no-hit the San Diego Padres in the National League's first combined no-hitter. Mercker threw a complete game no-hitter against the Los Angeles Dodgers on April 8, 1994. In addition to the game above in which Millwood and the Seattle Mariners tied the record by using six pitchers in a no-hitter, Millwood previously threw a complete game no-hitter against the San Francisco Giants on April 27, 2003, while with the Philadelphia Phillies. Both Mercker and Blue were All-Stars in the seasons of their combined no-hitters, and Blue also won the Cy Young Award and the Most Valuable Player Award during his career.
