This past Sunday, Oakland's Dallas Braden pitched the 19th perfect game in MLB history. The previous perfect game in the majors came courtesy of White Sox pitcher Mark Buehrle last July.
Buehrle also went on to set the major league record for most batters retired in a row with 45. The previous record was 41, and it was held by two pitchers. One was San Francisco's Jim Barr who did it in 1972, and the other guy is still playing today. Who is he?
