Top 50 Seattle Mariners
The Seattle Mariners began as an expansion team in 1977, and like many expansion teams, they took their lumps in the beginning. It took them until 1995, where they would not make their first playoff until 1995 with a team comprising of Alex Rodriguez, Ken Griffey Jr. Randy Johnson and Edgar Martinez, the sky seemed to be the limit, and they would make the playoffs in 1997, 2000, and 2001, but they were unable to win the American League Pennant.
To date, the Mariners are the only Major League Baseball team that has not participated in a World Series.
This list is up to the end of the 2025 season.

A key element for a thriving franchise rebuild is having a reliable pitcher who can consistently take the mound every fifth day, pitch innings, and support a team in transition. For the Seattle Mariners in the late 2010s and early 2020s, that crucial piece was Marco Gonzales. Drafted in the first round by the St. Louis Cardinals in 2013 from Gonzaga University, this soft-tossing left-hander overcame early injuries and a crowded roster before a pivotal July 2017 trade sent him to Seattle in exchange for outfielder Tyler O'Neill. When Gonzales joined the Mariners, he was an untested talent, but he…
Originally signed by San Diego and debuting as a 20-year-old fireballer in 2019, Andrés Muñoz’s trajectory faced an immediate obstacle when he needed Tommy John surgery. As a result, the Padres included him as part of a major seven-player trade to Seattle in August 2020. The Mariners' training staff managed his rehab meticulously, transforming him from a raw thrower with triple-digit velocity into one of the most effective and well-rounded closers in professional baseball. Muñoz’s rise to the top tier of modern relievers is fueled by a remarkable two-pitch arsenal that leaves major-league hitters completely stymied. His powerful, high-90s four-seam…
While the late 1980s and early 1990s Seattle Mariners were marked by exciting young talent, having a dependable, hardworking player behind the plate was essential for managing the demanding MLB schedule. For ten years, Dave Valle offered the Pacific Northwest consistent, defense-oriented stability. Drafted in 1978, the New York native spent years working through the minors before debuting in the majors in September 1984. After three seasons sharing catching duties in a competitive rotation, Valle took over as the main catcher in 1987 and maintained that role firmly. Valle was never expected to be a power hitter for the middle…
Every emerging franchise needs a reliable, level-headed hitter to solidify its lineup. For the late 1970s Seattle Mariners, that role was filled by Bruce Bochte. After four years of struggling for consistent playing time with the California Angels and Cleveland Indians, the smooth-swinging, left-handed first baseman and outfielder took a chance on the Pacific Northwest, signing as a free agent with the Mariners before the 1978 season. Bochte stepped into the Kingdome and quickly entered the best phase of his career, evolving from a platoon player to the key middle-of-the-order hitter for a young team. Bochte’s 1978 rookie season in…
Omar Vizquel is not primarily associated with the Seattle Mariners, but the player who would become one of the best defensive infielders ever would begin his career in the Pacific Northwest.
Tino Martinez was an excellent college baseball player at the University of Tampa and a Gold Medalist at the Seoul Olympics. Martinez was a first round pick (14th Overall) in 1988, and he would debut with Seattle in 1990.
Some baseball careers span decades of consistent, predictable play, while others are remembered for a single, spectacular moment of brilliance. Tom "Wimpy" Paciorek’s first ten years in the majors fall into the latter category. Drafted in the fifth round by the Los Angeles Dodgers in 1968, this tall (6’4") outfielder and first baseman was often stuck on the fringes of Hollywood, unable to secure a spot on a crowded, star-studded roster. After a short platoon role with the Atlanta Braves ended in May 1978 with his release, 31-year-old Paciorek signed with the Seattle Mariners, then a second-year team, looking for…
The vast shadow cast by "The Big Maple" continually sparks a blend of awe and ‘what-if' questions for sports fans in the Pacific Northwest. At 6'4" with a powerful left-handed throw, James Paxton had an arsenal of raw talent that, on any night, could break down any Major League Baseball team. Drafted out of the University of Kentucky in the fourth round of 2010, the British Columbia native made his debut in late 2013 with an impressive 3–0 appearance, immediately showing the high-energy potential that set him up as the future of the Mariners' left-handed pitching. Paxton’s story is closely…
The discussion regarding who owns the greatest overall closing career in Pacific Northwest history remains a compelling debate for baseball historians, with compelling cases to be made for the sustained durability of Kazuhiro Sasaki or J.J. Putz. However, when evaluating the single most dominant, high-efficiency peak ever constructed by a relief pitcher in a Seattle Mariners uniform, the conversation begins and ends with Edwin "Sugar" Díaz. Originally drafted as a starting pitcher in the third round of the 2012 draft, the slender right-hander from Naguabo, Puerto Rico, transformed into an absolute late-inning cheat code the moment the front office moved…
Long before modern analytics transformed front-office decisions, Ken Phelps exemplified what would become known as "Moneyball." During a time when raw batting average and physical build were the main metrics, the mustached, slow-footed slugger was often misunderstood by traditional scouts. They saw a defender who struggled and a player batting around .240 as a platoon candidate. However, those who looked deeper recognized a more dangerous talent: an efficient hitter with an exceptional strike zone sense and a remarkable ability to change the game with one swing. In March 1983, the Mariners traded for Phelps from the Montreal Expos, giving him…
After playing a decade in Japan with Yokohama, Kazuhiro Sasaki was a 32-year old rookie in Seattle, and with a decade of real experience, he easily won the 2000 American League Rookie of the Year Award. The former Central League MVP would finish third in the AL with 37 Saves.
The fact that Leon Roberts managed an 11-year major-league career is a minor medical and athletic miracle. As a child, he accidentally stabbed his right eye with a jackknife, leaving him with a severe focusing impairment in that eye and profoundly broken depth perception in his left. Terrified that a diagnosis would spell the immediate end of his professional aspirations, Roberts hid the injury from every coach, manager, and teammate he ever played with. Yet, despite essentially hitting blind in one eye, the 6'3" corner outfielder found a way to survive at the sport's highest level, engineering his absolute professional…
