GLENDALE—A pair of center fielders made their spring training debuts on the field Monday, but it was Alex Rios who had the better day.Rios, who has been in the White Sox lineup only once this spring because of a sore right shoulder, went 2 for 2 with a mammoth home run to deep center field in the Sox 5-4 loss to a Seattle Mariners split squad.Rios said his shoulder injury has not affected his swing.Franklin Gutierrez, the Mariners’ everyday center fielder in 2009 who signed a $20.5 million contract extension with this offseason, appeared in his first game after sitting out the first four with his own bum right shoulder. Gutierrez struck out and hit into a double play but drove in a run with a seventh-inning sacrifice fly.The White Sox starting lineup offered a glimpse at what could be their Opening Day group: outfielders Juan Pierre, Carlos Quentin and Rios; infielders Gordon Beckham, Paul Konerko, Mark Teahen and Alexei Ramirez; catcher A.J. Pierzynski; and designated hitter Mark Kotsay.Matt Tuiasosopo went 3 for 4 with two RBI for Seattle.
