Mariners vs Rangers Prediction

I’m looking at the over in this spot as both lineups are capable and both pitchers are young with small sample sizes. Bradford has a 4.45 ERA and 1.58 WHIP, while Anderson has a 5.40 ERA and 1.47 WHIP. Not ideal. Bradford has allowed 16 hits and 8 runs in his last 9.2 innings. Anderson has allowed 15 hits and 9 runs in his last 15 innings. In 10.2 innings at home, Anderson has a 5.91 ERA and a .308 allowed batting average. I expect some offense in this spot. Give me the over.
