Astros vs. Mariners Game 3 Betting: Can Seattle stave off the sweep at home?

Today, the Seattle Mariners will play their first home MLB playoff game since October 18, 2001. The Houston Astros will be hoping to spoil the party at T-Mobile Park, as they will go for a sweep and a sixth straight trip to the ALCS.

Were it not for Yordan Alvarez, the Mariners could be in position for a sweep of their own. But after winning Game 1 at Minute Maid Park with a three-run, walk-off blast, Alvarez flipped Game 2 with a go-ahead two-run shot in the sixth to help the Astros take a 2-0 lead to Seattle.

To try to extend their season, the M’s will turn to rookie George Kirby, who picked up the save in their unforgettable Game 2 comeback against the Toronto Blue Jays in the wild-card round. No sweat, right?

Houston Astros vs. Seattle Mariners Game 3 Prediction and Betting Picks

Astros vs. Mariners Prediction: Houston to win

Astros vs. Mariners Picks: Seattle 1st 5 innings -0.5 (Best Value: +135 at BetMGM), Houston ML (Best Value: -105 at BetUS) & Houston/Seattle over (Best Value: over 7 @ +100 at BetOnline, Bovada Sportsbook & BetMGM)

Sure, the Mariners did very well to have a chance to win both games in Houston, considering that they were underdogs in both games and that they were just 3-7 at Minute Maid Park in the regular season.

But to be in the positions to beat both Justin Verlander and Framber Valdez and come up completely empty-handed is a real missed opportunity.

The prospect of being able to play a postseason game in front of their long-suffering fans will certainly help the M’s be up for this one, but will they be able to give those fans one more home game?

Given how the first two games went, I don’t think the Mariners will wilt here despite being down 2-0 against an opponent that has had their number this season.

Kirby may be a rookie, but he has picked up some valuable experience in important games and situations already.

Home and Away Splits for Kirby and McCullers (2022 Regular Season)

• Kirby at home: 13 starts, 3-3, 3.28 ERA, 71.1 IP, 77 H, 29 R (26 ER), 9 HR, 10 BB, 77 K, .272 OBA, 1.22 WHIP
• McCullers on the road: 3 starts, 2-1, 3.57 ERA, 17.2 IP, 19 H, 7 R (7 ER), 2 HR, 9 BB, 21 K, .268 OBA, 1.59 WHIP

But the Astros have come up with the big hits when they needed to, in addition to getting some timely scoreless innings on the mound to keep the deficits within reach.

McCullers gave up more than two runs only once in his eight starts in the regular season, and dating back to last season, the righty has allowed more than two runs only three times in his last 16 starts (regular season and postseason combined).

I think the Mariners will find themselves in a favorable position for the third time in three games in this series. But just like the Astros came up clutch in the big moments in the first two games, they will do the same in Game 3 to put a swift end to Seattle’s dream season.
