The departure of Sisco goes with the earlier trades of Ambiorix Burgos to the Mets and of Mike MacDougal to the White Sox. When last season began, Sisco and Burgos were the setup men for MacDougal, the closer at the time.
Sisco had a 7.10 ERA in 65 games in 2006, with a 1-3 record and one save. He was a Rule 5 Draft pick from the Cubs prior to the 2005 season, when he surprisingly appeared in 67 games and posted a 3.11 ERA.
After this past year's slump, though, Sisco was sent to the Mexican Winter League for work.
Burgos was traded to the Mets on Dec. 6 for right-hander Brian Bannister, while MacDougal was dealt to the White Sox on July 24 for Minor League pitchers Tyler Lumsden and Daniel Cortes.
"Gload is a hard-nosed, tough-minded guy who battled his way through the Minors," Royals general manager Dayton Moore said on Saturday. "He fits with our team."
Gload, a left-handed hitter, has a .298 career average in parts of five seasons with the Chicago Cubs, Colorado Rockies and the White Sox.
"When you look at the balance of our team, we needed a left-handed hitter who can play first base and some other positions, too," Moore said.
Last season, Gload was 7-for-20 as a pinch-hitter, his .350 average tying for the American League lead. His 51 hits included three home runs and eight doubles, and he had 18 RBIs in 156 at-bats.
Sisco, at 6-foot-10, matches fellow southpaw Randy Johnson in height if not results. In Mexico, Sisco went 2-3 with a 4.59 ERA in seven starts.
Sisco became expendable after the Royals signed closer Octavio Dotel and picked up relievers John Bale, also a left-hander, as well as Kenny Ray and Joakim Soria, both right-handers.
In two seasons with Kansas City, Sisco went 3-8 with a 4.85 ERA and one save in 132 games. His big downfall last season was allowing a league-high 27 inherited runners (of 63) to score.
