Major League umpire John Tumpane captivated the baseball world Wednesday when he sprung to action and stopped a woman from jumping off the Roberto Clemente Bridge in Pittsburgh, just hours before calling balls and strikes as the home plate umpire at PNC Park later that night.
So who is this heroic umpire? Here are some things you should know about Tumpane:
Age: 34.
Hometown: Burbank, Ill.
Previous stops: Gulf Coast League, New York-Penn League, South Atlantic League, Florida State League, Eastern League and Pacific Coast League. Also worked 2008 SiriusXM All-Star Futures Game at Yankee Stadium and served as an instructor at the inaugural MLB Umpire Camp in 2006.
MLB debut: Aug. 2, 2010.
Tumpane worked his first Major League game as the second base umpire for this A's-Royals contest, a 6-0 A's win in Oakland. Trevor Cahill threw a three-hit shutout for Oakland, with Rajai Davis leading the way offensively, going 2-for-4 with a home run. The Royals team featured young and old: a rookie Greg Holland pitched in the game, while a 36-year-old Jason Kendall, in the final year of his career, caught for Kansas City.
Notable moments
Pressed into service
The thermometer reached 104 degrees with sweltering humidity on July 24, 2012, in St. Louis when umpire Eric Cooper became ill in the third inning of a matchup between the Cardinals and Dodgers. Tumpane was pressed into action, rushing to Busch Stadium to fill in for Cooper as the third base umpire. The Redbirds were able to score eight earned runs off Dodgers ace Clayton Kershaw -- the second-highest earned run total he's ever given up in a start -- cruising to an 8-2 win behind their ace, Adam Wainwright.
Front-seat view of history
Few could have predicted that history was about to take place on Aug. 21, 2015, in Houston when Astros starter Mike Fiers took the mound against the Dodgers. But with Tumpane behind home plate, Fiers submitted the performance of his career as he recorded the 11th no-hitter in Astros' history -- and the first by any team at Minute Maid Park. Tumpane called a fair game as Fiers walked three batters in the first three innings before settling in for an historic outing.

On the world stage
Tumpane got the chance to work one of the qualifiers for the 2013 World Baseball Classic, umpiring for Qualifier 4 at Xinzhuang Baseball Stadium in Chinese Taipei, where the hosts swept through the bracket to clinch a spot in the main draw. Tumpane worked alongside fellow American umpires D.J. Reyburn and Mark Ripperger, as well as the Korea Baseball Organization's Su-Won Choi, Nippon Professional Baseball's Kouichi Tanba and the Confederation of European Baseball's David Kulhanek. He was the first base umpire for the final game of the qualifier, when Chinese Taipei beat New Zealand to advance to WBC '13.
