Pitching Matchup

Seattle is sending right-hander Luis Castillo to the mound today vs. the Royals. He has made 13 starts this season and has a record of 5-6. Castillo’s ERA is 2.99, and he has a WHIP of 1.15. In his 13 appearances, he has turned in nine quality starts. Looking back at his most recent outing, Castillo didn’t allow a run vs. the Angels, picking up the win in seven innings of work. Before that, he had given up at least two earned runs in three straight starts. Opponents are batting .230 vs. Castillo this season.

He took the loss in that outing, going five innings. Overall, he has lost his last two starts.

Mariners vs. Royals Offense Outlook

Cal Raleigh has been a bright spot for the Mariners this season in terms of home runs, as his 11 homers are 10th in the league and the most on the team. However, he is batting just .200 this season. Julio Rodriguez has been a solid all-around hitter for the Mariners, batting .267 with five homers and 24 RBIs. Ty France is also a strong power threat, as his seven homers are 2nd on the team and 14th in the league.

Seattle’s offense has been one of the worst in the league this season, averaging just 3.8 runs per game. They are also the league’s worst team in terms of striking out, averaging nine strikeouts per game. Overall, they are batting just .221, which is 21st in the MLB.

As a team, the Royals are averaging 4.9 runs per game, which is 6th in the league. At home, they are even better, averaging 5.6 runs per game. Overall, they are one of the league’s top home run hitting teams and are batting .254, which is 5th in the league. One thing to keep an eye on is that they are 3rd in the league in strikeouts and are just 21st in walks.

Bobby Witt Jr. has been on a tear of late, hitting .409 over his last five games with two homers. For the season, he is batting .323 with 47 RBIs and 11 homers. Salvador Perez has also been a big power threat for the Royals, as he is batting .305 with 10 homers.

Free Mariners vs. Royals MLB Pick

Luis Castillo is coming off one of his best outings of the season vs. the Angels, but he is facing a Royals offense that just put up 10 runs. However, I see the Royals struggling offensively, just like nearly everyone has vs Castillo. I like Seattle on the money line for Saturday’s matchup.
