for some reason it's listing mike Piazza for SD and Vidro for Washington. Yahoo is doing the same thing with Vidro. Foxsports only recognizes 4 DH's (Thomas, Hafner, Ortiz, and Thome) So either Thomas was the worst DH against RHP in 2006 or he was in the middle of the pack ahead of only NL players (Vidro, Piazza,) injury prone (sweeney,) and Carl Everett.
