Key Storylines to Watch
Pitching Matchup: George Kirby of the Mariners comes into this game with a 5-5 record and a 4.50 ERA. The Mariners have won four of his last five starts. Kumar Rocker holds a 4-4 record with a 5.73 ERA. The Rangers have won his last two outings as he has slowly brought his ERA down recently.
Bullpen Usage: The Rangers could have the advantage in this game if it comes down to the two bullpens. Texas has the fourth-best bullpen ERA in baseball this season. The Mariners are not far behind in ninth place in that category. But Texas could get some much-needed wins in this series on the strength of their pen.

Final Thoughts
My best bet for this game is for the Rangers and Mariners to combine to go over the total of 7.5 runs in this matchup. The starting pitching on both sides has been inconsistent this season. Both Kumar Rocker and George Kirby could have their ups and downs in this game. I’ll rely on both offenses to score at least eight combined runs in what should be an entertaining game from the Emerald City.
