It took some extra work, but the Washington Nationals (31-48, 18-21 away) earned a 7-4 win in 11 innings to down the Seattle Mariners (38-40, 22-18 home) Tuesday night.

Not only did the Nats avoid the brooms in the series finale, they’re now in position to get out of the Pacific Northwest with a series win.

That’s where the oddsmakers have different ideas.

This one gets going Wednesday (June 28) at 4:10pm ET from T-Mobile Park in Seattle, WA. You can watch the game live on ESPN+.

Nationals vs Mariners Odds

Team Moneyline Runline Total
Washington Nationals +215 +1.5 (-102) Ov 8 (-114)
Seattle Mariners -260 -1.5 (-118) Un 8 (-106)

The MLB odds have the Mariners as hefty -260 favorites on the moneyline, an implied win probability of 72.22%. The total is set at eight runs — a figure the teams have crossed in the first two games of this series.

Washington has the worst record in the National League, and are already a whopping 21 games back of the Braves in the NL East. They are one of five teams that owns a better road record than home mark in the bigs.

Seattle is hovering around .500, but in the ultra-competitive AL West, they’re in fourth place, 9.5 games back of the division-leading Texas Rangers.

Probable Pitchers

It’s been a June to forget for Nationals’ starter Patrick Corbin. After a nice May where he went 3-1 and the Nats won five out of his six starts, the veteran lefty has lost all four of his starts this month.

Last time out, he lasted just five innings, shelled for seven hits and seven earned runs, giving up three homers in the process in a 13-3 drubblng at the hands of the San Diego Padres.

In four starts, Corbin has been tagged for 33 hits in 21 innings of work, while surrendering an average of four earned runs and  nearly three base on balls per outing.

Only one Mariner has double-digit at-bats against the 11-year vet. Eugenio Suárez is hitting .389 in 18 plate appearances vs Corbin, with a home run and four RBI.

1.97 SO/W Ratio 5.24

Seattle counters with 3rd-year man Logan Gilbert. The righty is coming off his best pitching performance of the season in a 13-1 pasting of the Baltimore Orioles.

Gilbert surrendered a season-low two hits across seven innings of work, allowing just one earned run, walking one and striking out five.

He has surrendered two runs or less in seven of his last 10 starts, and his 5.24 strikeout-to-walk ratio is sixth best in baseball.

Washington hasn’t seen much of Gilbert, as three players in their lineup have a combined eight at-bats against him.

Washington and Seattle Players to Look Out For

It’s a down year for the Nats, which has overshadowed a pretty good season for right fielder Lane Thomas. The sixth-year man leads Washington in hitting (.299), ranking just outside the top-10 in the bigs.

He also leads the Nationals in home runs (14) and RBI (41). Thomas picked up a couple of hits Tuesday night, giving him at least one hit in 20 of 24 June games.

For the M’s, Teoscar Hernandez went yard last game, giving him a team-leading 15 home runs on the season. Ty France leads the team in hitting with a .274 average.

With a hit Tuesday, he’s now picked up a hit in six of his last seven games. Suárez leads Seattle with 48 RBI.

Nationals vs Mariners Prediction

Washington has not been a great underdog bet this season, nearly 20 games under .500 at 29-48 on the season. They’re not particularly fond of the Pacific Northwest, either, having dropped six of their last eight at T-Mobile.

Seattle is 21-15 as a home betting favorite, a respectable 60% success rate. They’ve also taken care of business against weaker interleague foes, going 6-2 in their last eight games vs NL teams with a losing road record.

These aren’t the highest scoring teams in baseball, as the M’s rank 16th at 4.5 runs per game, while the Nationals are in 22nd at 4.2. After crossing the total twice in two games this series, perhaps these teams revert back to themselves.

Plus, the under is 3-0-1 in Gilbert’s last four starts against teams with a losing record, and the under has hit in five of the last eight head-to-head meetings.

Pick: UNDER 8 runs (-106)
