Alex Rios drove in three runs and had a single, double and triple in the White Sox' 7-4 victory Sunday against the Mariners. He continues to play right field at a solid level, and it goes hand in hand with what he's doing at the plate. After his .227 disappointment of 2011, he's having an encouraging start, to say the least. "He's been doing that for the last four or five days, staying in the middle of the field,'' manager Robin Ventura said. ''He looks good at the plate, and he's covering a lot of different things. He's not just hitting fastballs but offspeed pitches, kind of doing everything. He's pulling the inside pitch and going the other way.'' Rios looks comfortable at the plate, and "he looks really comfortable in right field,'' Ventura said. "That's where it starts.''
