Mariners vs Rangers Prediction
The Mariners won seven of the previous ten H2H encounters, including three of the last four. I am leaning toward the Ranger in this one, mostly because of Jacob deGrom, but he had his ups and downs in July, so I’ll opt for Over instead. DeGrom allowed multiple runs in seven of his last nine starts, and has a 4.00 ERA in two starts (9.0 innings) against Seattle this season. Logan Evans, on the other hand, surrendered 15 runs in his previous four starts, and I am backing the Rangers to score 3+ against him on Sunday. Go with Over.
