SCOTTSDALE, Ariz. (AP) David Peralta hit his first home run of the spring and Rubby De La Rosa pitched four scoreless innings for Arizona in a Diamondbacks split squad's 3-0 victory over the Kansas City Royals on Saturday.

De La Rosa, the No. 4 starter in the Diamondbacks' rotation, had been rocked for five runs in four innings in his first two starts. But he blanked the Royals on four hits, striking out five with no walks, in front of a record Salt River Fields crowd of 13,514.

All three runs came in the first inning off Kansas City starter Kris Medlen, two of them on Peralta's homer. Medlen settled down after that. He gave up six hits in three innings, striking out two and walking one.
