Mitch Haniger is a professional baseball outfielder born on December 23, 1990, in Mountain View, California.[3] He played college baseball at Cal Poly San Luis Obispo, where he was named the 2012 Big West Conference Player of the Year and led the conference in home runs (13), RBIs (64), and slugging percentage (.626).[8] The Milwaukee Brewers selected him in the first round (38th overall) of the 2012 MLB Draft.[1] Haniger made his Major League debut with the Arizona Diamondbacks in 2016 before being traded to the Seattle Mariners in November 2016 along with infielder Jean Segura in exchange for Ketel Marte and Taijuan Walker.[1] He appeared in six seasons with Seattle across three separate stints (2017-2019, 2021-2022, 2024), with a one-year stint with the San Francisco Giants in 2023.[2] His breakout season came in 2018 when he made the American League All-Star team and finished 11th in AL MVP voting.[1] That year, he hit .285 with 26 home runs, 93 RBIs, and a .859 OPS across 157 games, accumulating 6.5 Wins Above Replacement.[1] In 2021, Haniger had another strong season, hitting 39 home runs (5th in the AL) and driving in 100 runs.[3] Over his career, Haniger recorded 688 hits with a .250 batting average and 130 home runs across 2,755 at-bats.[3] His 60 home runs at T-Mobile Park rank fifth-most in the ballpark's history, and his eight walk-off hits are the most in Mariners franchise history.[1] He also received AL MVP votes in both 2018 and 2021, and helped the Mariners reach the postseason in 2022, their first appearance since 2001.[1] In November 2025, the Mariners released Haniger at age 34, concluding his tenure with the organization.[1]

Kyle Seager is an American professional baseball player born on November 3, 1987, in Charlotte, North Carolina.[2] He is the brother of fellow Major League Baseball players Corey Seager and Justin Seager, a fact he embraced by wearing the nickname "Corey's Brother" on his jersey during the 2017 MLB Player's Weekend.[4] Seager attended the University of North Carolina, where he established himself as one of the nation's top college baseball players. During his sophomore season in 2008, he earned second-team All-America honors and won the Walter Rabb Award as the Tar Heels' most improved position player. He set a single-season UNC record with 30 doubles and posted 75 RBIs that year.[1] He was selected by the Seattle Mariners in the third round of the 2009 MLB Draft with the 82nd overall pick.[2] Making his MLB debut on July 7, 2011, Seager spent 11 seasons with the Mariners as a third baseman, becoming one of the franchise's most significant players.[4] Over his career, he accumulated 1,395 hits, 242 home runs, and 807 RBIs across 1,480 games, finishing with a .251 batting average and 37.0 WAR.[2] His consistency was remarkable—he played in at least 154 games in eight different seasons, a distinction matched by only a few active players at the time.[4] Seager ranks among the top five in Mariners franchise history in runs, hits, extra-base hits, and home runs, trailing only legends like Ken Griffey Jr., Edgar Martinez, Ichiro Suzuki, and Alex Rodriguez in WAR among position players.[4] Known as "Cap" by his teammates for his leadership qualities, Seager served as Seattle's de facto captain throughout his tenure. After the Mariners declined his 2022 club option, he became a free agent and subsequently played for the Texas Rangers.[7] His 11-year commitment to Seattle earned him a standing ovation during his final game in 2021, reflecting his significance to the franchise and its fanbase.
