The club added right-hander Javier Avendano, first baseman Gabe Jacobo and catcher Hector Alvarez in the Triple-A phase. Each pick cost the club $12,000, and the players can't be demoted below Triple-A without first being offered back to their original team.
The 21-year-old Avendano appeared in nine games for Class A Batavia in the Cardinals' farm system. He went 1-2 with a 3.14 ERA in 14 1/3 innings while striking out 19 and walking eight.
Jacobo, 24, hit .270 with 10 home runs and 49 RBIs in 86 games last season for Double-A Arkansas. He was a 10th-round pick in the 2008 First-Year Player Draft.
The 20-year-old Alvarez hit .229 with no homers and six RBIs in 27 games in the Gulf Coast League. He is a former midseason All-Star in the Dominican Summer League.
The Blue Jays were not eligible to make a selection in the Major League portion of the Rule 5 Draft because they did not have any room available on their 40-man roster. Toronto did not lose any players to another team in either the Major League or Minor League portion of the Rule 5 Draft.
