Tim Lincecum tosses three scoreless innings Friday

Giants pitcher Tim Lincecum maintained a 0.00 spring ERA by throwing three scoreless innings Friday, allowing just two hits in his team's 5-0 win against the Royals.

"My curveball felt good, I threw a few sliders in for first pitches -- and that was a pitch that it didn't take too long to get the feel for," Lincecum told MLB.com after the start.

Lincecum threw two scoreless innings in Monday's debut. He'll look to continue last year's improvement from a dismal 2012 season when the regular season begins.
