Overnight ratings dipped slightly for the Major League Baseball Home Run Derby. The 2012 MLB Home Run Derby drew a 4.7 overnight rating on ESPN Monday night, down a tick from both last year (4.8) and 2010 (4.8). Though essentially on par with the last two years, the 4.7 overnight puts the Home Run Derby on pace for its lowest final rating since 2003 (3.5). For some perspective, NBA All-Star Saturday night drew a 4.4 overnight on TNT in February. (Monday’s overnight from Sports Business Daily), reports Sports Media Watch.
