- What: MLB Regular Season Game
- When: June 30, 2025
- Who: Kansas City Royals vs. Seattle Mariners
- Time: 6:40 p.m. PST
- Where: T-Mobile Park (Seattle, WA)
The Kansas City Royals (39-45) will take on the Seattle Mariners (43-40) in the first game of a four-game series on Monday at T-Mobile Park in Seattle, with the first pitch at 6:40 p.m. PST.
This is their first meeting of the season, and the teams split their last season’s games 3-3.
The Royals are struggling, having lost seven of their last eight games, including a 5-1 defeat against the LA Dodgers. Their offense has been inconsistent, scoring one run or fewer in five of those losses.
Bobby Witt Jr. is hitting .285-11-43, but that’s a drop from his .332-32-109 performance in 2024. Top prospect Jac Caglianone has been brought up but is hitting just .165 with two home runs and only one hit in his last 26 at-bats.
The Mariners, meanwhile, return home after a successful 6-4 road trip, winning 2 of 3 against the Rangers, including a 6-4 victory on Sunday marked by Mitch Garver’s game-winning 2-run homer.
Catcher Cal Raleigh, who leads MLB with 32 homers, has not hit one in the last six games.
Pitching Matchup
Michael Wacha (4-7, 3.33 ERA) will make his 17th start, bringing a 1.22 WHIP and averaging 7.2 strikeouts per nine innings over 92 innings pitched.
In his last outing, he lost after allowing 3 earned runs in 6 innings against the Rays. Wacha is 2-1 with a 4.32 ERA in his last five starts against Seattle.
On the other hand, George Kirby (1-4, 5.40 ERA) is set for his eighth start, with a 1.28 WHIP and 8.8 strikeouts per nine innings over 36 2/3 innings.
He also lost his last game, giving up 1 earned run in 6 innings against the Twins. Kirby is 1-0 with a 2.25 ERA in three career starts against the Royals.
I’m taking the Mariners to cover the run line -1.5 at +135 odds.
I just don’t believe the Royals have the offensive firepower to compete. They’ve only managed to score more than 2 runs in 2 of their last 8 games.
Best Bet: Mariners -1.5 runs at +135 odds
