About Mark Teahen
Mark Thomas Teahen (born September 6, 1981) is an American-Canadian former professional baseball infielder who played in Major League Baseball (MLB) for the Kansas City Royals, Chicago White Sox, and Toronto Blue Jays. He graduated from Yucaipa High School in 1999 and attended St. Mary's College in California. Teahen was drafted 39th overall in the 2002 draft by the Oakland Athletics with a sandwich pick between the first and second rounds. He was featured in the book Moneyball, which noted the Athletics considered that Teahen could have the potential to become the next Jason Giambi. Prior to the 2009 World Baseball Classic, Teahen, whose father was born in St. Marys, Ontario, became a naturalized Canadian citizen and played for Team Canada in that event. In 2011, Teahen and Brett Lawrie both started in the infield for the Blue Jays, marking the first time they had two Canadians in the starting lineup. == Professional career == === Kansas City Royals === Oakland traded him to Kansas City in 2004, along with Mike Wood, as part of a three-way trade that sent Carlos Beltrán to the Houston Astros, Octavio Dotel from the Astros to the Athletics, and John Buck from the Astros to the Royals. Although he had been one of the most highly regarded prospects in the Oakland organization, he became available when the Athletics were able to sign Eric Chavez to a long-term contract.
