Yep Seattle strikes out a lot. But it seems to be an outlier that should correct a bit. Wacha will need a good start to get to six

This Mariners roster not only leads the league in strikeouts but they also struggle from the plate. That being said, 6 Ks in a big number for Michael Wacha and I don't believe the matchup is quite as bad as it appears at first glance. Wacha tends to really struggle the 2nd and 3rd time through the order, thus if he doesn't record a lot of strikeouts in the first 2-3 IP, he's very unlikely to eclipse this line. Wacha has failed to record 6 Ks in 6/8 games this season. Additionally, the Mariners have solid career numbers featuring minimal Ks against Wacha.

Logan Gilbert is having a strong season and has been a viable Cy Young candidate through a quarter of the season. While 6 Ks isn't a particularly daunting number for Gilbert considering he has eclipsed this prop in seven of his eight starts this season, it is a very tough matchup against a Royals lineup that sports the second lowest K rate in the league. An additional component I like is KC has faced Gilbert a lot and not only do they own a solid .821 OPS against him over 59 ABs but have only struck out 15x, good for just a 25% K rate.
