What fans should know before attending a Mariners game at T-Mobile Park in 2024

The Mariners open the 2024 season hoping to get back to the playoffs after coming up just a few games short a season ago. The Red Sox finished last in the American League (AL) East in 2023 with a 78-84 record.

Brayan Bello, 24, will be the starter for Thursday's opener against the Mariners. He had a 12-11 record with a 4.24 earned run average (ERA) over 28 starts in his rookie season a year ago, and Bello is the youngest Opening Day starter for Boston since 1995. Luis Castillo will again get the ball for the Mariners on Opening Day after making his third All-Star team in 2023 and finishing fifth in voting for the AL Cy Young Award, given annually to the league's best pitcher.

T-Mobile Park is located at 1250 1st Ave. S in Seattle’s SODO neighborhood. Fans are advised to “plan ahead and consider all the transportation options available.”

All main T-Mobile Park gates open 90 minutes before the first pitch. The T-Mobile 'Pen gate, located next to the Mariners bullpen in centerfield, opens two hours before the first pitch. Fans will only be able to access the ‘Pen area of the ballpark until all other main gates open. Here is the summary of the policy from the Mariners' website.

• Clear bags no larger than 12 inches by 6 inches by 12 inches are permitted. One-gallon clear plastic zip-top bags are allowed.

Sealed, clear plastic water bottles up to 32 ounces, baby bottles, beverages related to medical needs, and unopened, soft-sided single-serve containers like juice boxes are permitted. Soda, coffee, or other beverages are not allowed. Guests may bring in one empty plastic reusable bottle 32 ounces or smaller.

T-Mobile Park is cashless; only credit, debit, or mobile pay options like Apple Pay or Google Pay are accepted. 

Tamari Bar is one of the new offerings at Mariners home games, featuring a Japanese fusion menu with options like curry rice, katsu curry rice and curry donuts dip.

A third Walk-Off Market will be open in section 105 to go along with the spots in sections 126 and 141. Among the new offerings will be "The Double MitchWich," which is a sandwich with two halves named to honor the two current Mariners with the same first name: Mitch Haniger and Mitch Garver. The Garver side has pulled pork, ham, Swiss cheese, dijonaise and sliced pickles on Cuban bread, while the Haniger side has grilled chicken, tomatoes, bacon, fried avocado and Havarti cheese on a flatbread. A portion of the proceeds will be donated to Seattle Children's hospital.

Salt and Straw will have two new flavors available in the ballpark, including a T-Mobile Park special Wild-Forged Berry Slab Pie. This new treat consists of wild berries "forged from the slopes of Mt. Baker in Washington" that are simmered into a filling and mixed with double-based pie crust in a salted vanilla ice cream,

MOTO Pizza is bringing its widely popular Crab Pizza to its T-Mobile Park locations all season after it was made available for special events at the venue in the past.

The Mariners' starting lineup will be mostly static from the 2023 season, with a few key additions in the middle of the lineup. Jorge Polanco is expected to be the Mariners' second basemen after coming over from the Minnesota Twins in an offseason trade. Polanco has missed at least 50 games in each of the past two seasons but was among the top hitters in Spring Training down in Arizona.

Mitch Garver is the other new face of the lineup and is expected to serve as the designated hitter in most games. Garver won a championship with the Texas Rangers last season and hit .270 with 19 home runs and 50 runs batted in (RBI) over 87 regular-season games.

Returning stars like Julio Rodriguez, Cal Raleigh and J.P. Crawford will be counted on to lift the Mariners back into the postseason.

The Mariners' pitching staff should be among the best in MLB, with Castillo, George Kirby, Logan Gilbert, Bryce Miller and Emerson Hancock making up the starting rotation. Miller and Hancock showed flashes of brilliance after making their debuts in 2023, while the 26-year-old Kirby looks to build on an All-Star campaign in 2023. Bryan Woo was set to be the fifth starter after a promising rookie season but will begin 2024 on the injured list.

Redmond-born Austin Voth and former Houston Astro Ryne Stanek are among the new additions to the Mariners' bullpen, and fan favorite Andres Munoz will be back.
