In this Diamondbacks vs Rangers Prediction, the Rangers are coming as -120 home favorites. Both teams have split wins in the previous two games in this series and I don’t trust either pitcher in this matchup, as they both have a combined 10.69 ERA. Arizona has a bad bullpen and the Rangers are better against right-handed pitching and I expect the bats to remain hot after a 11-game run yesterday. Take the over 8.5 in this one.
