"I had good building blocks yesterday and built on that," Nathan said.
Nathan needed just 11 pitches (nine strikes) in his only inning of work against Double-A hitters from Kansas City. He had two strikeouts and a groundout.
Nathan's fastball was at 92 to 94 mph and he had a good slider and curve Tuesday. It's the third outing in four days for Nathan, something he said he's never done in spring training before.
"Normally I pitch two straight days and then take two days off," Nathan said earlier Tuesday. "But this is a chance to shock my arm and help prepare it for what I'll have to do during the season."
* RHP Colby Lewis pitched six innings and gave up no runs on three hits with two walks and six strikeouts. He threw 98 pitches and appears ready for the season.
"I felt good," Lewis said. "I worked both sides of the plate and my changeup was really good."
Lewis said he's still coughing a bit from feeling the desert air, but otherwise is in good shape.
