The Seattle Mariners and Houston Astros have both had disappointing starts to the season.

The Mariners have won seven straight games against the Astros, including a four-game sweep in Seattle last month.

Mariners vs. Astros Probable Pitchers
- Mariners: George Kirby (4-2, 2.94 ERA)
- Astros: Peter Lambert (2-2, 2.42 ERA)
George Kirby has been stellar this season in Seattle. He had a few hiccups early on in the season, allowing four runs against the Yankees and three in Texas, but he’s allowed two earned runs or fewer in every start besides them. That includes 7.2 IP with two runs allowed on seven hits against the Astros on April 13.
Peter Lambert started the season in the minors but has been impressive at the major-league level. After allowing four runs in five innings against the Cardinals in his first start, he’s allowed a total of two runs in 17.1 innings against the Guardians, Orioles, and Astros in his last three.

Mariners vs. Astros Best MLB Prop Bets
Mariners Best MLB Prop Bet
- George Kirby UNDER 2.5 Earned Runs Allowed (-131)
Kirby has been as consistent as they come for the Mariners.
The righthander has allowed UNDER 2.5 earned runs in five straight starts, including two runs in 7.2 innings against the Astros.
Houston has scored one run combined in its last two games, and has been held to three runs or fewer in six of its last seven contests.
Mariners vs. Astros Prediction and Pick
The Astros are struggling offensively, and that should continue against Kirby and the Mariners.
Instead of taking Seattle as road favorites, though, I’m going with the UNDER in tonight’s game. Kirby has been fantastic and Lambert has held his own on the mound for Houston.
Pick: UNDER 9 (-119)
