For nearly two months, Oakland Athletics first baseman Nick Kurtz was the most consistent presence on a Major League baseball diamond. Since early April, opposing pitchers struggled to find a way to keep the reigning American League Rookie of the Year off the basepaths. However, all historic runs eventually reach their conclusion, and for Kurtz, that moment came on Tuesday night at Sutter Health Park in West Sacramento.
The Nick Kurtz on-base streak officially ended at 48 games following an 0-for-4 performance in a 4-1 loss to the Seattle Mariners. While the streak’s conclusion marks the end of a remarkable chapter in the 2026 MLB season, Kurtz exits the spotlight having etched his name alongside one of the greatest sluggers in the history of the franchise.
Matching a Legend: Tying Mark McGwire’s Franchise Record
By reaching base in 48 consecutive games, Nick Kurtz matched the Athletics’ single-season franchise record set by Mark McGwire in 1996. McGwire, who famously reached base in 48 straight games during that season, eventually extended his personal mark to 62 games when accounting for the end of the 1995 campaign. For Kurtz, matching the single-season record in just his second year in the big leagues solidifies his status as one of the game's elite disciplined hitters.
Kurtz’s run is the longest on-base streak seen in the Major Leagues since 2018, when Shin-Soo Choo reached safely in 52 consecutive games for the Texas Rangers. To put the 48-game feat into further perspective, Kurtz surpassed franchise icons like Rickey Henderson (46 games) and Hall of Famer Jimmie Foxx (47 games) during his ascent up the record books.
A Tough Night at the Plate Against Seattle Pitching
The Seattle Mariners’ pitching staff proved to be the kryptonite for the 23-year-old first baseman on Tuesday. Mariners starter Emerson Hancock set the tone early, stifling the Athletics' lineup with six scoreless innings, allowing only one hit and striking out three. Kurtz struggled to find his timing against Hancock, contributing to a night where the A's offense could only muster a single run.
As the game entered the late innings, the tension grew with every Kurtz plate appearance. His final opportunity to keep the Nick Kurtz on-base streak alive came in the bottom of the eighth inning. Facing left-handed reliever Gabe Speier, Kurtz fought through the at-bat but ultimately struck out swinging. It was his third strikeout of the night, a rare occurrence for a player who entered the contest leading the majors with 52 walks and a .444 on-base percentage.
The Anatomy of a 48-Game Masterclass
The streak, which began on April 3, was defined by elite plate discipline and a refusal to chase pitches out of the zone. Over the course of the 48 games, Nick Kurtz maintained a .308 batting average and showcased the power that earned him the 2025 AL Rookie of the Year award, totaling eight home runs and 37 RBIs during the stretch. Athletics manager Mark Kotsay praised Kurtz’s approach throughout the run, noting that the young star never sacrificed his plan to hunt for hits.
- Duration: 48 games (April 3 – May 25, 2026)
- Franchise Rank: Tied for 1st in single-season history (Mark McGwire)
- Plate Discipline: 52 walks in 53 games played this season
- League Standing: Currently leads MLB in on-base percentage (.437)
Looking Ahead for Kurtz and the Athletics
Despite the end of the individual milestone, Nick Kurtz remains the focal point of an Athletics team currently battling for supremacy in the American League West. With a 27-27 record, Oakland sits just 1.5 games ahead of the Mariners in a tightly contested division race. Kurtz’s ability to draw walks and drive up pitch counts will be vital as the team looks to bounce back from the 4-1 loss and maintain their lead in the standings.
While he fell short of the all-time MLB record of 84 games held by Ted Williams, Kurtz’s 48-game streak serves as a reminder of his rapid evolution into a premier MLB talent. As the Athletics prepare for the series finale against Seattle, all eyes will be on how the young first baseman starts his next run at history.
