Seattle Mariners 2020 Betting Guide: World Series Odds And More

Mariners odds Seattle World Series

Seattle struggled in all facets in 2019, finishing 29th in collective batting average (.237), 23rd in collective ERA (5.00), and 21st in bullpen ERA (4.77). It is clearly time for this franchise to turn the page and for the first time since 2004, the Mariners will start a season without “King” Felix Hernandez. Gone too are veteran lefties Wade LeBlanc and Tommy Milone, as well as catcher Omar Narvaez, who had a breakout year with 22 home runs in 2019.

This season, Kyle Seager is the only projected starter over 30-years-old for Seattle. Speedster Dee Gordon is in the final year of a contract that guarantees him $13.8 million and he could be moved before the adjusted Aug. 31 trade deadline. Speedy outfielder Mallex Smith can slot into his role as the Mariners table setter.

The Mariners are longshots with +50000 odds to win the World Series at DraftKings Sportsbook. In the unlikely event that Seattle wins a championship, a $10 bet on that futures market would profit $5000. The Mariners are getting +25000 odds to win the American League and are huge underdogs with +8000 odds to win the AL West.

The strength of the AL West will make it very tough for Seattle to post a solid record during this shortened season. The Mariners are projected to win 24.5 games at DK with -112 for the Over or Under, but we like the Under considering Seattle will have to play 40 games against strong teams like the Astros, Athletics, Angels, and Rangers.

Smith is the second favorite to lead the majors in stolen bases with +400 odds, trailing only Royals infielder Adalberto Mondesi.

Seattle Mariners betting breakdown

2019 Record: 68-94

Key losses: RHP Anthony Bass, 3B Ryon Healy, RHP Felix Hernandez, LHP Wade LeBlanc, LHP Tommy Milone, C Omar Narvaez, OF Domingo Santana

Key additions: LHP Wei-Yin Chen, RHP Carl Edwards Jr, OF Carlos Gonzalez, RHP Yoshihisa Hirano, RHP Taijuan Walker

Projected starters/lineup:

1. 2B Shed Long (L)

2. SS J.P. Crawford (L)

3. 3B Kyle Seager (L)

4. C Tom Murphy (R)

5. DH Dan Vogelbach (L)

6. LF Kyle Lewis (R)

7. 1B Evan White (R)

8. RF Jake Fraley (R)

9. CF Mallex Smith (L)

Projected rotation: LHP Marco Gonzales, LHP Yusei Kikuchi, RHP Kendall Graveman, LHP Justus Sheffield, RHP Taijuan Walker

Projected closer: RHP Matt Magill

Bullpen strengths: Matt Magill is the likely closer despite only five saves and 12 games finished in 2019 mostly out of the pen. Magill did post a solid 3.63 ERA with 28 SO in 22.1 IP. Sam Tuivailala was impressive in the 23 games (23.0 IP) he appeared in last season. Tuivailala posted a 2.35 ERA with 3 GF, 13 HA, 27 SO.

Bullpen weaknesses: Yoshihisa Hirano may also compete for the closing role. The 36-year old only has four career saves and 21 games finished in two MLB seasons so is a veteran without a lot of closing experience. Hirano posted a 4.75 ERA with 51 hits allowed in 53.0 IP in 2019. Carl Edwards is likely to make the roster despite a 2019 with a 5.87 ERA in 20 games for the Cubs (15.1 IP) before being traded to the Padres, where he only appeared in two games.

Key stats from 2019

  • C Omar Narvaez had a breakout 2019 with 22 HRs, 55 RBIs and a .278 BA in 132 games but will likely back up Tom Murphy who hit 18 HRs, 40 RBIs and a .273 BA in 75 games last season.
  • First season since 2004 without ‘King” Felix Hernandez.
  • 2B Dee Gordon is in the final year of a contract that guarantees $13.8M could be used as a backup or trade piece.
  • Kyle Seager will be the only starter over the age of 30. Seager hit .260/.339/.524 with 17 HRs and 45 RBIs in the final 68 games of 2019.
  • DH Daniel Vogelbach slumped after his All-Star Game appearance hitting just .162/.286/.341 with 9 HRs in the final 59 games (MLB.com).
