Draft and career as a shortstop
Santos, who is of Mexican American descent, was drafted out of Mater Dei High School in Santa Ana, California by the Arizona Diamondbacks in the first round of the 2002 Major League Baseball Draft. Between 2002 and 2005, Santos steadily worked his way up through the Diamondbacks' farm system all the way to Triple-A Tucson, where he hit 21 doubles and 12 home runs in 2005.
On December 27, 2005, Santos was sent to Toronto along with Troy Glaus in exchange for Miguel Batista and Orlando Hudson. In 2006, he hit .214 with 5 home runs and 38 RBI in 128 games with Toronto's Triple-A affiliate, the Syracuse Chiefs. He attended the Blue Jays' 2007 spring training, but did not make the active 25-man roster. After his struggles at Triple-A Syracuse in 2006, Toronto assigned Santos to their Double-A affiliate, the New Hampshire Fisher Cats for the 2007 season. Santos won the Home Run Derby preceding the Eastern League All Star game in 2007 at Norwich's Dodd Stadium.
On May 13, 2008, Santos was claimed off waivers by the Minnesota Twins. He became a free agent at the end of the season and signed a minor league contract with the Chicago White Sox, but on March 20, 2009, was traded to the San Francisco Giants in exchange for future considerations. Less than two weeks after the trade he was brought back to the Chicago White Sox organization and sent to extended spring training to convert from infielder to pitcher.
Santos has pitched at four levels of the Sox minor league system in 2009, beginning at the Single-A Kannapolis Intimidators and ending at Triple-A Charlotte Knights. He posted a combined ERA of 8.16, but struck out more than a batter an inning.
On March 30, 2010, Santos was named to the White Sox opening day active roster. He won the 7th and final spot in the bullpen over Greg Aquino.
Santos' high 90's mph fastball and nasty slider are his primary weapons, but he also throws a changeup and curve ball. Santos earned his first major league win by pitching two innings of shutout baseball, striking out two in an 11 inning win over the Detroit Tigers on August 5, 2010.
He established a new Major League record with his 25th straight scoreless appearance on the road to start a season in a 6–3 win over the Baltimore Orioles at Camden Yards on August 11, 2011. Mariano Rivera had previously held the record since 2005. Santos' achievement was actually part of a longer such streak of 30 which began in the previous campaign.
On December 6, 2011, he was traded to the Toronto Blue Jays for Néstor Molina.
