 Biographical Information
Kerwin Danley is a major league umpire.
Danley was picked in the 12th round of the 1979 amateur draft by the Los Angeles Dodgers out of high school. In college, Danley was a teammate of Tony Gwynn at San Diego State University. Unlike Gwynn, Danley was an All-American outfielder. He was so honored in 1983, joining Ben Abner and Shane Mack in the outfield. His 108 hits in 1983 are still (as of 2010) tied for third most in SDSU history.
Danley was not drafted out of college. He went on to umpiring instead, starting in the 1985 Northwest League. He moved on to the 1986 California League, 1987-1989 Texas League, 1990-1995 Pacific Coast League and 1996-1997 International League.
He started working National League games as a substitute umpire in 1992, while continuing to spend the majority of his time in the minors. In 1998, Danley was promoted full-time to the major leagues. He worked the Division Series in 2000. Kerwin worked the 2007 ALCS and 2007 All-Star Game and worked his first World Series in 2008.
