The Kansas City Royals and the Seattle Mariners meet Friday in MLB action from T-Mobile Park. We will look at this from a betting perspective and determine the best bets for this game. Here’s a Kansas City Royals vs. Seattle Mariners prediction.
The Kansas City Royals will send out Cole Ragans for the start here and Ragans is 1-4 with a 5.00 ERA and 33 strikeouts this season. In his career, Ragans is 0-0 with a 2.79 ERA and 13 strikeouts against the Mariners. Bryan Woo will start for Seattle here and is 1-2 with a 3.86 ERA and 27 strikeouts this season. This will be Woo’s second career start against the Royals.
The Kansas City Royals come into this game looking to bounce back from a 6-3 loss at the hands of the Athletics last time out to sit at 12-19 this season. After this series, the Royals will host the Guardians in a series at home.
Kyle Isbel has 21 hits with 3 home runs and 8 RBIs while Jonathan India has 2 home runs and 8 RBIs on the year. Jac Caglianone has 22 hits with 5 doubles, 2 home runs, 4 RBIs and a triple while Bobby Witt Jr. has 35 hits with 9 doubles, 2 home runs and 15 RBIs and Vinnie Pasquantino’s added 17 hits with 3 doubles, 2 triples, 3 home runs and 14 RBIs on the year. Maikel Garcia also has 31 hits with 8 doubles, 3 home runs and 11 RBIs this season. Carter Jensen’s also chipped in 6 home runs and 16 RBIs this season.
The Seattle Mariners come into this game looking to build on their 5-3 win over the Twins last time out to sit at 16-16 this season. After this series, the Mariners will take on the Braves in a series at home.
Brendan Donovan has 17 hits with 3 doubles, 3 home runs and 8 RBIs while Luke Raley has 5 home runs and 13 RBIs this season. Cole Young’s added 32 hits with 4 doubles, a triple, 3 home runs and 19 RBIs and Cal Raleigh has 24 hits with 4 doubles, 7 home runs and 18 RBIs as well this season. Randy Arozarena has 33 hits with 9 doubles, 2 home runs and 11 RBIs as well on the year. Josh Naylor also has 24 hits with 4 home runs and 15 RBIs as well on the year. Julio Rodriguez has also added 32 hits with 6 doubles, 2 home runs and 12 RBIs.
I’m on the Mariners in this one. I still don’t trust this Royals bullpen in the later stages of games and Cole Ragans hasn’t really had any luck in any of his starts this season. I think Woo is the better starter here and I think he bounces back with a strong start at home here. Give me the Mariners.
