Seattle Mariners prospect Boston Smith, primarily a catcher, took the field in left for the Peoria Javelinas during the Arizona Fall League. The 23-year-old was acquired in exchange for Luis Castillo and has shown impressive offensive numbers throughout the season. His move to left field may provide Seattle with a potential option to fill the left-field gap left by Randy Arozarena, who is set to hit free agency. Arozarena had a career-best season, prompting questions regarding his replacement. Smith's experience in left field could factor into Seattle's roster decisions ahead of the 2027 season.
