KC sends Mazzaro, Robinson to Pirates for pitchers

The Royals have traded right-hander Vin Mazzaro and first

baseman Clint Robinson to the Pittsburgh Pirates for minor league

pitchers Luis Santos and Luis Rico.

Mazzaro was 4-3 with a 5.73 ERA for the Royals while filling in

as a spot starter because of injuries last season. Robinson struck

out twice in his first four major league at-bats. Both were

designated for assignment on Nov. 20.

The 21-year-old Santos pitched for both Dominican Pirates clubs

last season, combining for a 6-3 record and a 2.44 ERA in 14 games,

including 12 starts. In 62 2-3 innings, he allowed 42 hits, walked

20 and struck out 74 while holding opponents to a .184 average.

Rico, who turns 19 on Thursday, was 0-1 with a 7.04 ERA for the

Dominican Pirates.

Also on Wednesday, the Royals announced that right-hander Chris

Volstad and catcher Brayan Pena chose free agency after clearing

waivers and getting outrighted to the minor leagues.

Volstad and Pena also were designated for assignment on Nov.
