The Royals today signed right-handed pitcher John Thomson to a one-year Major League contract. Thomson will join the team tonight in Milwaukee, at which time a determination will be made as to when he will appear for the Royals. In a corresponding move, the Royals place pitcher Scott Elarton on the 15-day disabled list (retroactive to June 20) with a right foot sprain. Thomson, 33, is a nine-year Major League veteran, compiling a 62-84 record and a 4.69 ERA in 214 career games, including 210 starts. After originally being selected by Colorado in the seventh round of the 1993 draft, he pitched for the Rockies (1997-2002), Mets (2002), Rangers (2003) and Braves (2004-2006). His best season came in 2004 with Atlanta, when he went 14-8 with a 3.72 ERA in 33 starts, helping the Braves to the playoffs. His only season in the American League came in 2003 with Texas, when he tied for second in the league in starts (35), finished seventh in innings (217.0) and tied for seventh with three complete games.
