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.

20.
