The 2026 MLB season is shaping up to be a thrilling one, with standout performances and record-breaking achievements. Here's a breakdown of the standout players and their remarkable accomplishments in May, along with my personal insights and commentary.
AL Player of the Month: Nick Kurtz
Nick Kurtz of the Athletics had a historic month, flashing the abilities that earned him the AL Rookie of the Year Award in 2025. Kurtz batted an impressive .333 with five home runs, 26 RBIs, and a 1.025 OPS in May. What's truly remarkable is his 48-game on-base streak, which ties an A's single-season record. Kurtz is currently MLB's leader in on-base percentage at .440, a testament to his exceptional plate discipline. Personally, I find it fascinating that Kurtz's performance has been so consistent, especially considering the high level of competition in the American League. His ability to maintain such a high on-base percentage while hitting for power is a rare and valuable skill.
NL Player of the Month: JJ Bleday
JJ Bleday, the outfielder for the Reds, had a torrid May, hitting .301 with eight home runs, 25 RBIs, and a 1.018 OPS. This performance is even more impressive considering that Bleday was designated for assignment by the Athletics just a few months prior. The Reds' decision to sign him and give him a chance has paid off handsomely. Bleday's ability to adapt to a new team and excel in a new league is a testament to his talent and work ethic. What makes this particularly fascinating is the potential for Bleday to become a cornerstone of the Reds' future.
AL Pitcher of the Month: Spencer Arrighetti
Spencer Arrighetti of the Astros had an outstanding May, allowing just three earned runs in five starts with a 0.93 ERA. His season ERA of 1.34 is the best in MLB, behind only Shohei Ohtani's 0.82. Arrighetti's ability to excel on the road, including matchups with the Red Sox and Cubs, is a testament to his resilience and skill. The no-hitter he took into the eighth inning against the Rangers is a highlight of his career. Arrighetti's performance has been a key factor in the Astros' success this season, and his ability to lower his ERA further could be a significant factor in their playoff hopes.
NL Pitcher of the Month: Cristopher Sánchez
Cristopher Sánchez of the Phillies had an incredible May, allowing no runs in five starts while striking out 45 in 39 innings. His 44 2/3 consecutive scoreless innings is the longest active streak in MLB, surpassing Grover Cleveland Alexander's franchise record. Sánchez's ability to maintain such a high level of performance over a long stretch is a testament to his pitching prowess. The Phillies' decision to sign Sánchez and give him a chance has paid off, and his performance has been a key factor in their success this season. What many people don't realize is that Sánchez's success is not just a result of his pitching ability but also his mental toughness and ability to remain focused under pressure.
AL Rookie of the Month: Munetaka Murakami
Munetaka Murakami of the White Sox had a standout May, adding eight home runs to his 12 from March and April. His .556 slugging percentage and .938 OPS for the month are impressive, and he's the first White Sox player to win Rookie of the Month in over five years. Murakami's ability to adapt to the MLB level and excel in a short period is a testament to his talent. The White Sox's decision to draft and develop Murakami has paid off, and his performance has been a key factor in their success this season. If Murakami continues to develop, he could become a cornerstone of the White Sox's future.
NL Rookie of the Month: TJ Rumfield
TJ Rumfield of the Rockies had a solid May, batting .310 with four home runs, 12 RBIs, and an .883 OPS. His performance has been a key factor in the Rockies' success, and he's the eighth Colorado player to win the award since its inception in 2001. Rumfield's ability to take a step forward in May, after a solid start to the season, is a testament to his talent and work ethic. The Rockies' decision to acquire Rumfield and give him a chance has paid off, and his performance has been a key factor in their success this season.
AL Reliever of the Month: Cade Smith
Cade Smith of the Guardians had an outstanding May, saving all 13 games he appeared in and striking out 25 in 13 2/3 innings. His 1.32 ERA and ability to maintain a high level of performance over a short period is a testament to his talent. Smith's performance has been a key factor in the Guardians' success this season, and his ability to lower his ERA further could be a significant factor in their playoff hopes. The Guardians' decision to sign Smith and give him a chance has paid off, and his performance has been a key factor in their success this season.
NL Reliever of the Month: Mason Miller
Mason Miller of the Padres had an incredible May, allowing no earned runs in 9 2/3 innings while striking out 20. His 0.72 ERA and 49 strikeouts in 25 innings are impressive, and he's the first player to win three straight Reliever of the Month Awards since Edwin Díaz. Miller's ability to maintain such a high level of performance over a long stretch is a testament to his talent. The Padres' decision to sign Miller and give him a chance has paid off, and his performance has been a key factor in their success this season. If Miller continues to dominate, he could become a cornerstone of the Padres' future.
