Mickey Gasper’s August didn’t just turn heads in Boston - it put him in a statistical neighborhood with some of the biggest names the sport has ever seen.
The 30-year-old finished the month with a 1.671 OPS in 42 plate appearances, a blistering stretch that followed his Aug. 16 recall from Triple-A after Masataka Yoshida went on the injured list with a hamstring strain. Gasper wasted no time making the call-up count, and he capped the month with another homer on Monday.
That late blast was his sixth of August and came in a game the Red Sox desperately needed. Gasper opened the scoring with a first-inning home run against the Mariners, then watched Boston rally from an 8-5 deficit and win on Trevor Story’s 10th-inning walk-off single.
The numbers around Gasper’s month are eye-catching enough on their own, but the history behind them is even wilder. A graphic during the game had him alongside Ted Williams and Barry Bonds for the best OPS figures ever recorded in a single month.
Our research showed that Gasper’s mark trails only Bonds’ 1.828 OPS in April 2004 among calendar months with at least 40 plate appearances. Williams’ staggering 2.314 OPS in September 1957 came in just 33 plate appearances.
There’s an obvious caveat there, since 40 plate appearances is still a fairly arbitrary cutoff. If the bar moves up to something closer to the 70-plate-appearance standard that roughly mirrors a batting-title qualifier, Gasper no longer stays on the list.
But the bigger point remains: across the full history of Major League Baseball, a list can be built that puts Barry Bonds at No. 1 and Mickey Gasper at No. 2.
What makes the run even more surreal is that Gasper had never homered in a Red Sox uniform before Aug. 17, despite logging 142 plate appearances with the club.
And then came the strange twist. In the middle of his surge, Gasper was sent back to Triple-A for a day on Sunday as part of the corresponding moves for Story and Roman Anthony returning from the injured list. He was back up the next day when Willson Contreras landed on the IL.
It’s a dizzying sequence, and it says plenty about how strange the Red Sox’s 2026 turnaround has been. Gasper’s last two weeks fit that theme perfectly, and now he’ll head into September with a little more runway to see if the hot streak keeps rolling.

Red Sox Turn To Intriguing Young Arm As Roster Crunch Hits Boston
A roster squeeze brought a fresh look to Bostons pitching plans, with the Red Sox selecting the contract of right-hander Jedixson Paez from Triple-A Worcester and lining him up to make his major league debut as a starter. The move came as part of a broader shuffle, as the club created room on the 40-man roster by designating infielder Brett Harris for assignment.
The Red Sox also reinstated utilityman Isiah Kiner-Falefa from the 60-day injured list, while left-hander Eduardo Rivera was placed on the 60-day injured list after being recalled. For Paez, the promotion puts an intriguing young arm in the spotlight at a moment when Boston is balancing health, depth and immediate innings all at once. [Read more 🡒]
Red Sox Take An Unexpected Mound Gamble In Playoff Push
The Red Sox leaned into a little roster juggling before opening against the Mariners, and the most eye-catching move was the decision to bring up right-hander Jedixson Paez for a first major league start. Boston also reinstated Isiah Kiner-Falefa from the 60-day injured list, designated Brett Harris for assignment and recalled Eduardo Rivera before moving him to the 60-day injured list, a flurry of moves that gave the club a fresh look as it kept navigating a crowded stretch of the schedule.
For Paez, the assignment adds another layer of intrigue because it comes after he was returned to the organization earlier in the season. Boston does not often hand a start like this to a pitcher in that spot, which is why this one stands out in the middle of a playoff push. The Red Sox are clearly searching for the right combination of health, flexibility and upside, and Paez will now get a chance to show he can fit into that mix when the games matter most.

Red Sox September Call-Up Plan Still Leaves One Big Roster Question
The Red Sox are expected to get a familiar, useful piece back when rosters expand on Sept. 1, with veteran utility man Isiah Kiner-Falefa lining up as the clubs likely position-player addition. Interim manager Chad Tracy confirmed Kiner-Falefa as the front-runner, a move that fits the late-season need for coverage all over the diamond and a steady presence for a team trying to firm up its roster for October.
Kiner-Falefa brings the kind of versatility clubs tend to value when the calendar turns to September and the games carry more weight, especially with postseason experience in his background. The open question for Boston is on the mound, where the team has not yet settled on a pitching addition, leaving one final choice to shape how the expanded roster looks for the stretch run.
