The postseason in the MLB starts with wild card games on Friday, October 7, with four games on the schedule, including this American League clash, so make sure you check out the best Mariners vs. Jays betting pick and odds.

Seattle and Toronto will play the first of a best-of-three ALWC series at Rogers Centre, and the Blue Jays are -145 moneyline favorites on MyBookie Sportsbook, while the total is set at 7 runs. These AL rivals have met seven times this season, and the Mariners lead 5-2.

Mariners enter the season with three wins in a row

The Seattle Mariners finished the regular season with a 90-72 record, the fifth-best in the American League. They concluded the regular campaign with three consecutive wins, beating the Detroit Tigers in a four-game series. Seattle is playing well of late, winning seven of the previous nine games, all at home.

Ty France hit a game-winning RBI in the 9th inning in Game 4 against the Tigers to make it 5-4 for the Mariners. Julio Rodriguez, Mitch Haniger, and Luis Torrens blasted a home run each. Marco Gonzalez (10-15) pitched for 7.0 innings in a no-decision and surrendered three runs on eight hits with five strikeouts and two walks. Erik Swanson (3-2) was credited with a win.

Luis Castillo (8-6) will open this wild card series on the mound when he faces Toronto on Friday. The 29-year-old right-hander started 25 times this year with Cincinnati and Seattle and registered an excellent 2.99 ERA, 1.08 WHIP, and 167/45 K/BB ratio in 150.1 innings.

Blue Jays beat the Orioles to conclude the regular season

The Toronto Blue Jays ended the regular season with two wins ahead of the Mariners and the fourth-best record in the AL (92-70). After sweeping the Boston Red Sox in a three-game series, allowing just three runs in the process, the Blue Jays won the series against the Baltimore Orioles. They won two out of three and will enter the postseason with five wins in six games.

Toronto scored four runs in the 7th and 8th inning to secure a 5-1 victory over the Orioles on the final day of the regular season. Otto Lopez and Bradley Zimmer chipped in two RBIs apiece as the Blue Jays decided to rest some of their key players. It was a bullpen game for Toronto, and Yusei Kikuchi (6-7) got the win in the end, his sixth of the campaign.

Alek Manoah (16-7) will get to the hill for the Blue Jays on Friday against Seattle. The 24-year-old right-hander started 31 games in his second year in the MLB and impressed with a sublime 2.24 ERA, 0.99 WHIP, and 180/51 K/BB ratio across 196.2 innings of work.



  • 3-7 in the last ten road games
  • 1-5 in the last six road games vs. a right-handed starter
  • 3-10 in the last 13 after scoring five runs or more in their previous game


  • 5-1 in the last six overall
  • 21-8 in the last 29 during game 1 of a series
  • 16-5 in the last 21 games following an off day

Seattle Mariners vs. Toronto Blue Jays Pick

The home-field advantage could be crucial in this series, but also the fact that the Blue Jays will start their best pitcher to open it. Alek Manoah didn’t allow more than two runs in his previous four starts, and he managed to shut the opponents out in each of his last two starts. He has one start and a loss against Seattle this year but posted a very strong 2.45 ERA over 7.1 innings. Luis Castillo was also good in his lone start against Toronto; although he took a loss, he did register a solid 3.00 ERA in 6.0 innings. The Blue Jays are better when batting against righties (.263 BA with 4.93 runs per nine innings), while the Mariners are better against southpaws.

Pick: Take the Blue Jays to win (-145)

The Total

Manoah is in excellent form, but Castillo is not playing badly himself, so I don’t expect to see a high-scoring affair in game 1 of this ALWC series. The pitchers will give their best to keep their respective teams in the game, and I’d be surprised if they combine for more than seven runs. Under is 6-0 in Manoah’s last six starts vs. American League West rivals. Moreover, Under is 5-2 in the last seven H2H meetings, while Under is 4-0 in the previous four H2H duels in Toronto.

Pick: Go Under 7 runs (-110)
