The Kansas City Royals announced Wednesday they 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 November 20th.
Robinson was a key part of the Omaha Storm Chasers' run to the Pacific Coast League championship in 2011 as he became just the second player in franchise history to drive in 100 runs. He finished the season with a .326 batting average, 23 home runs and 100 RBIs.
He followed that up with a .292, 13 homer and 67 RBI campaign in 2012, helping the team to a second straight division and American Conference title. The 25th-round 2007 draft choice was a two-time Triple-A All-Star with Omaha and tied the single-season franchise record with 37 doubles in 2012.
Mazzaro was a combined 9-4 with five saves and a 4.06 earned run average in 44 games, 14 in relief, for the Storm Chasers during the 2011-12 seasons. He was also instrumental in the 2011 championship run, starting and winning game two of the American Conference Championship Series at Round Rock and game two of the PCL Championship Series over Sacramento at Werner Park.
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 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 in 11 games for the Dominican Pirates last season.
