Meet Rob Refsnyder
So, who is this player making his way to Seattle? Here’s an in-depth look at his career.
A Brief Background
Over the course of his ten-year journey in Major League Baseball (MLB), Refsnyder has played for six different teams. He was drafted in the fifth round by the New York Yankees in 2012 and made his MLB debut three years later in 2015. During his early years, he became somewhat of a journeyman, playing for five teams in his first six seasons and participating in a total of 232 games with the Yankees, Toronto Blue Jays, Tampa Bay Rays, Texas Rangers, and Minnesota Twins.
In 2022, Refsnyder found his stride with the Boston Red Sox, where he took on the role of a fourth outfielder. Throughout his four seasons with the team, he posted a wins above replacement (bWAR) of 3.6. His performance was impressive, boasting a slash line of .276/.364/.440, which translates into 27 home runs, an .804 OPS, and a 123 OPS+ over 309 games. Notably, he achieved an OPS+ of at least 130 in three of those four seasons.
Born in Seoul, South Korea, Refsnyder moved to Laguna Hills, California for high school. He shone at the University of Arizona, leading the team to a national championship in 2012 and earning the title of Most Outstanding Player at the College World Series. With his upcoming stint, he will join the ranks of notable Korean-born players in Mariners history, including Shin-Soo Choo, Cha-Seung Baek, and Dae-ho Lee.
A Reliable Bat
Refsnyder has established himself as a formidable platoon hitter, especially against left-handed pitchers. Since the beginning of 2022, he has showcased an impressive slash line of .312/.407/.516, resulting in a remarkable .924 OPS across 501 plate appearances against lefties. Among all MLB hitters during this timeframe, he ranks third in on-base percentage against lefties—trailing only the likes of Aaron Judge and Paul Goldschmidt. He also stands out with rankings of sixth in batting average, sixteenth in slugging percentage, and seventh in overall OPS against left-handed pitching over the last four years.
In terms of contact, Refsnyder achieved a hard-hit rate of 52.3%, a barrel rate of 12.3%, and an average exit velocity of 92 mph in 2025, all of which surpass the league averages, according to Baseball Savant. However, it’s worth noting that his strikeout rate hit 25.8% last season, indicating a need for improvement in that area.
Versatility on the Field
Throughout his MLB career, Refsnyder has demonstrated versatility by playing six different positions, most frequently occupying the corner outfield spots. He has not seen action in center field since 2023, nor has he played in the infield since 2020 when he made a few appearances at first base.
His arm strength has consistently ranked in the 80th percentile or higher for the past five seasons, based on metrics from Baseball Savant. However, his sprint speed is below average, and he poses little threat on the base paths, with just 22 career stolen bases to his name.
