The Dodgers have signed three more draft picks: 10th-rounder Erik Kanaby, a left fielder from Lamar University, 13th-rounder Bobby Blevins, a right-handed pitchers out of Le Moyne College and 15th-rounder Cal Stanke, a right-handed pitcher out of the University of Wisconsin-Oshkosh. The club also has agreed to terms with 16th-rounder Andres Santiago, a right0hander out of Colegio Carmen Sol in Puerto Rico and 17th-rounder Franklin Jacobs, a first baseman out of Robert B. Glenn High School in North Carolina. The club now has signed a total of five picks, including 11th-rounder Paul Koss, a right-handed pitcher out of USC and 12th-rounder Jessie Mier, a catcher from Lewis and Clark State, both of whom signed over the weekend. Club officials hope to have first-rounder Chris Withrow, a right-handed pitcher from Midland (Texas) Christian High School, in for a physical on Friday, after which he would attend that night’s game with the Angels. Withrow is expected to sign — probably for a bonus in the $1.3 million to $1.4 million range — within the next week.
