Seattle is one of baseball’s hottest offenses, averaging 5.6 runs per game over their last 13 outings . Backed by dynamic bats like Cal Raleigh (32 HR) and Jorge Polanco, their lineup can explode in bursts while occasionally going cold. Luis Castillo takes the mound: at 4-5 with a 3.69 ERA, he’s been solid but was recently walloped by the Minnesota Twins to the tune of 5 runs in his start en route to a loss.

Texas has stabilized after a poor May, going 11–6 in June, but their offense has struggled—averaging just 3.4 runs per game, with most production coming from two blowout afternoons against Minnesota. Their pitching has kept them afloat, especially with Nathan Eovaldi returning from injury without a rehab outing. Still, Rangers’ bats lack consistency—veterans like Seager and García have underperformed, making run support an ongoing concern.

Expect a shifting battle between Seattle’s potent bats and Texas’s solid pitching behind Leiter, the starter. The inconsistent lineup of Texas against the power on the side of the Mariners will put us on the side of Seattle. We will be taking a shot on the Seattle Mariners to win this on 6-3.
