No, that wasn’t a rerun. Game 2 just seemed a lot like Game 1, with Yordan Alvarez hitting game-winning home runs in each. The Houston Astros are now one win away from winning their AL Division Series against Seattle.

The Astros are -2400 to win their series, according to Caesars Sportsbook. Their opponent, the Mariners, are listed at +1200, the best odds you can get for Seattle to come back from an 0-2 hole.

Odds for Game 3 are -110 for both teams at Caesars. Both DraftKings and BetMGM price the series as -115 (Astros) and -105 (Mariners). Basically it’s a pick’em, with the Astros even money or slight favorites on the road.

If Houston wins, they will advance to the AL Championship Series for a sixth consecutive season, which would set a record for an American League team.

Up 2-0, the Astros are favorites to win the AL pennant: -130 according to Caesars. Houston is also now the favorites, per Caesars, to win the World Series, with odds priced at +220. That means a winning $100 bet on the Astros to win the Fall Classic would pay $220. The longest odds on Houston to win the World Series are +250 from DraftKings.

The Mariners are +5500 to win the World Series at DraftKings, but you can get +6000 at Caesars.

Alvarez hit a walkoff three-run homer in the bottom of the ninth to win Game 1 on Tuesday. In Game 2, he smacked a two-run homer in the sixth that gave the Astros a 3-2 lead they never relinquished.

Mariners vs. Astros Pitching Matchup, Game 3 ALDS

Lance McCullers Jr. (4-2, 2.27 ERA) vs. George Kirby (8-5, 3.39 ERA)

Is there no end to the pitching depth of the Astros? Their Game 3 starter, Lance McCullers Jr. has been stellar since returning to the rotation in mid-August. In all eight of his starts in the regular season, McCullers allowed no more than three earned runs. He allowed only nine earned runs in his last six. The stage is not too big for him: the veteran righthander has made nine starts in the postseason, and in six of them he allowed just two earned runs or less.

Kirby gets his first postseason start, and it couldn’t come with more pressure. Seattle hasn’t hosted a playoff game in more than two decades, and T-Mobile Park will be as loud as a Rolling Stone reunion concert. Kirby won’t get a long leash: if he struggles, manager Scott Servais will need to go to his pen quickly. All hands on deck.

Astros, Mariners ALDS Game 3 Prediction

Seems like a lifetime ago that Seattle was drunk with euphoria after Cal Raleigh’s home run to clinch a playoff spot for the Mariners. Since, the team has toppled the Blue Jays in the Wild Card round, but suffered two crushing defeats at the hands of the Big Orange Crush (also known as the Houston Astros).

We expect McCullers to pitch well and the Astros to hand a lead to the best bullpen in the AL. Result? A three-game sweep for the ‘Stros.
