When the Twins claimed a shortstop off of waivers on this date in 2008, they probably wouldn’t have guessed that Sergio Santos would go on to become a closer for their division rivals. Yet that’s exactly what’s happened since Minnesota claimed Santos from the Blue Jays three years ago.
Santos, selected in the first round of the 2002 draft by the D’Backs as a shortstop, arrived in the Toronto organization late in 2005, when the Blue Jays sent Orlando Hudson and Miguel Batista to the D’Backs for Troy Glaus. The Twins then claimed Santos on May 16th, 2008, before he had ever pitched in a professional game. After Santos posted a .242/.279/.374 line in the minors, the Twins let the infielder go.
Later in the offseason the White Sox signed Santos and within months, he was on the move again. The White Sox traded Santos to San Francisco late in Spring Training on the condition that the Giants would find him an everyday job in Triple-A. Unable to provide Santos with a regular role, the Giants sent him back to Chicago less than two weeks later.
Once the 2009 season began, Santos began the transition to the mound, as Yahoo's Jef Passan explained last year. The right-hander posted an 8.16 ERA through 28 2/3 innings for four different White Sox affiliates and allowed 37 hits and 20 walks, while striking out 30.
By 2010, Santos had graduated to Chicago's 'pen. He posted a 2.96 ERA in 51 2/3 innings with 9.8 K/9 and 4.5 BB/9 as a rookie. Armed with a 95 mph fastball, Santos has posted similar numbers through 19 frames this year. He has yet to allow an earned run and he has 10.4 K/9 and 4.3 BB/9 as Ozzie Guillen’s most effective reliever – almost certainly not what the Twins were envisioning when they claimed the former shortstop off of waivers on this date in ’08.
