My analysis

After a small five-game skid starting two weeks ago, the Baltimore Orioles have quickly taken four of their last five including three of four from the World Series-defending Texas Rangers. On Tuesday they will open up a three-game set in Seattle, who have had the opposite luck as of late.

The Seattle Mariners have now lost eight of their last 11 and desperately need to turn things around quickly as the massively surging Astros have come within three games of their division lead. Making matters worse is that they will open the series with the Orioles against Grayson Rodriguez, who in a limited sample has handled the Mariners well.

Across the 29 combined plate appearances, the Mariners have seen Rodriguez thus far, they've hit just .125 average and have struck out 34.5% of the time. That's good for just three combined hits across the entire roster, and none have been for extra bases.

Plus the Mariners have been one of the league's worst teams against righties this year, batting to the seventh-lowest OPS as a team in 2024 while posting a 28.4% strikeout rate. And while Seattle has George Kirby on the mound tonight, he hasn't had glowing results against the Orioles in his career.

Across a much larger 104 plate appearances, Baltimore has hit him to a .260 average (a high mark in today's game) and a .530 slugging percentage and has only struck out 19.1% of the time - notably lower than his 23.7% rate for his career.

The Orioles are also the league's second-best team against right-handers according to OPS and the third-best team according to wRC+.

Orioles moneyline

George Kirby Under 7.5 strikeouts

Mitch Garver Under 0.5 hits

Capitalizing on the Orioles' track record of not swinging and missing on Kirby, the Under on his strikeout prop makes a lot of sense.

Combined with the fact that Kirby has only gone over this total for today just once in his last four outings and just three times in his 11 starts since the start of May, there is some solid value there.

And then on the other side of the matchup, we can capitalize on Grayson Rodriguez's proficiency against this lineup by targeting the batter he has had the largest sample size against and the best results against by looking at Mitch Garver as he is a lowly 1-for-7 against Rodriguez in his career and has struck out a whopping four times.
