The MLB undefeated Labor Day System play is on Arizona on the run line at 4;10 eastern/ Home Favorites on Labor day at -220 or higher that were not big dogs in their last game are a perfect 10-0 since 2004 vs an opponent off a loss like Colorado. These teams win by over 4 runs per game so we will play this one on the RUN LINE at -1.5/ Arizona has a big pitching edge with Kelly over Lambert and the Rockies are a terrible road team. Look for Arizona to take the opener
