Ronald Rosario spent the first three months of the season looking like a catcher still trying to find his footing. July has flipped that script in a hurry.
The Red Sox prospect has caught fire with Double-A Portland this month, posting a 1.484 OPS and adding a pair of home runs in Saturday night’s blowout win. For a player who opened the year with OPS marks of .692 in April, .668 in May and .648 in June, the turnaround has been dramatic.
Rosario is 23, so he’s not a wide-eyed teenager racing through the system. Even so, catcher is one of the toughest positions to develop at, because so much of the job is tied to defense and the bat often takes longer to catch up. That’s part of what makes this surge so interesting for the Red Sox.
The numbers this season are already a big step forward from last year. Rosario hit a career-high 11 home runs with Portland in 2025, but he also finished with a .201 average and a .599 OPS across 98 games. In 45 games this year at the same level, he’s up to nine homers, a .281 average and an .821 OPS.
That makes this his best offensive season as a professional outside of his debut in 2021 in the Dominican Summer League.
For an organization that can never really have enough catching depth, Rosario’s bat heating up is exactly the kind of development that matters. If this is a real breakthrough, the Red Sox could have something useful down the road. If not, July still gave Rosario a month where just about everything he hit found a way to work out in his favor.

Red Sox Suddenly Face A Risky Deadline Reunion Debate
The Red Sox have spent enough of this season building a legitimate pitching staff and staying in the playoff race that any deadline conversation now comes with a different kind of pressure. Boston does not need a splash for the sake of it, but the market is already starting to point toward names that would force the front office to weigh present-day help against long-term flexibility.
One scenario making the rounds would test that balance in a hurry, because it involves a familiar face with a hefty contract and a reliever who would instantly become one of the most coveted arms available. For Boston, the appeal is obvious on paper, but so is the risk of getting pulled into a deal that is as complicated financially as it is intriguing on the field. [Read more 🡒]
Trevor Story Suddenly Looms Over Red Sox Wild Card Push
Bostons sweep of the Rays has the club rolling at exactly the right time, and the timing only sharpens the intrigue around Trevor Story. The Red Sox are sitting in the No. 3 American League Wild Card spot and are just one game behind Cleveland for No. 2, which means every bit of help matters as the calendar turns toward the stretch run.
Story has been out since May 14 after sports hernia surgery, but his return is starting to feel close enough to matter in the standings conversation. A minor league rehab assignment appears near, though he has stopped short of putting a date on it, and once that assignment begins Boston will have a limited window before it has to make a decision on activating him.

Red Sox Fans May Need To Take Gage Ziehl More Seriously
Gage Ziehl keeps giving the Red Sox reasons to pay attention, even if his path to Boston still looks like a longer-term project. The right-hander turned in another sharp outing for Double-A Portland, working five scoreless innings with eight strikeouts and showing the kind of command and swing-and-miss stuff that can make a prospect start to move up the organizational ladder.
Ziehls rise is worth tracking because he has already been through a lot of movement for a pitcher still trying to establish himself. Boston got him this offseason in the deal that sent Jordan Hicks to the White Sox, and he had previously been traded from the Yankees to Chicago, so there has been plenty of roster churn around him already. He is not likely to reach the majors this season, but if the strong outings keep coming, Triple-A Worcester could be the next stop. [Read more 🡒]
