The Mariners travel to Southern California for a quick two-game interleague set with the Padres starting Tuesday night at Petco Park.

The Mariners closed out a disappointing nine-game homestand with consecutive losses to the Blue Jays, reducing Seattle's lead atop the AL West over Houston to two games entering Tuesday. The Padres are also looking to end a two-game slide following a home series setback to the Diamondbacks as San Diego seeks its 50th win.

Mariners vs Padres odds for Tuesday night have the Mariners installed as -135 moneyline favorites as they send All-Star right-hander Logan Gilbert to the hill. The over/under is set at 7.5 runs (-125o / +105u).

Seattle Mariners

Seattle owned a solid 44-31 record on June 18 following a victory at Cleveland. However, the Mariners have slid backward since then by losing 12 of their past 17 games, including dropping six consecutive series.

The Mariners squandered a 4-1 lead in Sunday's extra-innings defeat to the Blue Jays, finishing its homestand at 3-6 against Minnesota, Baltimore, and Toronto.

Logan Gilbert will try to get the Seattle ship back in the right direction on Tuesday as the right-hander was tagged for four runs in less than six innings of a 4-1 loss at Baltimore his last time out.

Gilbert dominated the Padres in a pair of starts last season by tossing seven innings each in two low-scoring victories. In the first outing at Petco Park, Gilbert scattered three hits and struck out six in a 4-1 win, followed by a 2-0 shutout at home as he struck out 12 batters and yielded a single hit.

From a first five innings perspective, Gilbert is 15-3 to the F5 under this year, although he has seen the over hit in his prior two starts.

In the last 10 road series openers, Seattle has stumbled to a 3-7 record since early May, which included blowing an 8-0 lead at Kansas City in a 10-9 walk-off defeat last month.

In the road favorite role of -120 or higher, the Mariners have posted a 4-8 record in the last 12 games in this price range.

San Diego Padres

San Diego went through an impressive 12-3 stretch from June 19 through July 5 before a pair of losses to Arizona this past weekend. The Padres allowed 24 runs across the three-game series, as San Diego needed a ninth-inning rally on Friday to capture the opener, 10-8.

In Petco Park's last four series openers, the Padres own a perfect 4-0 record while scoring six, seven, seven and 10 runs, with three of those games going over.

Following San Diego's pitching woes against Arizona, it will look to turn things around behind rookie Adam Mazur, who is making his 7th career start.

The Padres rallied past the Rangers, 6-4, in Mazur's last trip to the mound, marking San Diego's third straight win with the right-hander starting.

Mazur allowed seven hits and four runs in four innings, but the Padres stormed back with four unanswered runs to get the Minnesota native off the hook.

At home, Mazur has been involved in three high-scoring games as the Padres have scored at least one run in the first inning each time.

Since 2022, the Padres have dropped six of the last eight meetings with the Mariners, including a 1-3 mark at Petco Park. Also, Gilbert has had San Diego's number in this stretch, as the Padres are 1-3 in their past four games against the newly-minted All-Star.

Mariners vs. Padres

Betting Pick & Prediction

It's hard to ignore that Seattle has the edge on the mound tonight and that Gilbert has owned the Padres over the years.

However, the Mariners have not been the team they were earlier this season, and the Padres should be motivated here as a rare home underdog following two blowout losses to the Diamondbacks.
