On Friday the MLB Blowout System is on the Arizona Diamondbacks. Game 962 at 9:45 eastern. Arizona fits a Big blowout system tonight that is 13-0 and plays on home favorites off a road win and scored 4 or less runs on 10+ hits, vs an opponent off a road dog loss with 1 or less errors provided the total in the game is more than 7. Arizona has won 10 of 14 as a home favorite in this range and Colorado is 1-11 as a road dog in this range off a 1 run road loss. Chatwood goes for Colorado and he is 1-6 in September road starts and has a 8.71 era in his last 3 starts. McCarthy for Arizona has a solid 1.87 era in his last 3 starts. Colorado has lost 6 of the last 7 here in the desert. With the system winning by nearly 4 runs per game we will back Arizona tonight.
