Seattle enters this game with advantages in several key areas. The Mariners have been the better team statistically, holding edges in runs scored, home runs, on-base percentage, slugging percentage, and team ERA. Their pitching staff has consistently kept opponents in check, and Hancock has been one of the biggest reasons why. His 2.78 ERA and 1.01 WHIP suggest he is well equipped to handle a Mets lineup that has struggled for long stretches this season.
New York deserves credit for its recent surge. The sweep of Miami provided a much-needed boost, and Soto appears to be heating up at the plate. However, the Mets remain below .500 on the road and continue to operate without several key contributors. Warren has pitched effectively, but asking him to maintain a 1.40 ERA over a larger sample is a difficult expectation, especially against a Seattle club that has been swinging the bat better during its current winning streak. I'll take the Mariners to get the win here with all of that in mind.
