I don't have the exact transcript handy, but during today's Cubs game, with the score tied in the top of the ninth and a man on second, the announcers implied that Carlos Marmol "would be careful with Luis Gonzalez" since Gonzo is 2-4 in his career off Marmol, while the on-deck hitter was 0-3.
The on-deck hitter? Hanley Ramirez.
Justice wasn't served, as Marmol walked Gonzalez then induced a flyout from Ramirez that was a few feet from being a 2-run double. The system works!
