Lazaro Montes Homers and Drives in First RBI at Fenway Park
Lazaro Montes made an immediate impact in his major league debut on Tuesday night, September 1, 2026. After drawing a walk in his first-ever plate appearance against Boston starting pitcher Jedixson Paez, Montes collected his first career hit and first career RBI in the third inning by singling home Josh Naylor.
The 21-year-old slugger wasn’t finished. In the fifth inning, Montes connected off Red Sox reliever Wyatt Olds, driving a solo home run to center field for his first career major league home run. According to Heavy.com, tracking data showed the blast traveled 407 feet out of Fenway Park.
Joining Mariners Franchise History
Montes etched his name alongside several notable Seattle Mariners debuts with his multi-hit performance. According to statistics shared on X by MLB researcher Sarah Langs and reported by Heavy.com, Montes became just the seventh player in franchise history to homer in his major league debut, joining a list that includes Jamie Nelson (1983), Alvin Davis (1984), Greg Dobbs (2004), Kenji Johjima (2006), and Kyle Lewis (2019).
Furthermore, Langs noted that Montes is the first Mariners player to record a multi-hit MLB debut since Ichiro Suzuki accomplished the feat in his 2001 regular-season opener after arriving from Japan. Montes also joined Shane Monahan (1998) and Al Chambers (1983) as the only three players in Seattle history to tally multiple hits and multiple RBIs in their very first big league game.
Scouting Profile and Minor League Path
Signed by Seattle as an international free agent in January 2022, the 6-foot-5, 210-pound outfielder entered the majors carrying immense raw power. According to FanGraphs scouting reports, Montes generated a 65-grade raw power tool projected to reach 70 on the standard scouting scale.
Prior to his September call-up, Montes played across Double-A Arkansas and Triple-A Tacoma during the 2026 minor league season. According to minor league tracking data, he slashed .249/.369/.558 with 38 home runs—hitting 25 in Arkansas before a July promotion added 13 more at Tacoma. Despite a high strikeout rate that hovered around 30.6% in the minors, his prodigious raw power translated immediately to the major league level on Tuesday night in Boston.
