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.
