Pirates have another 100-mph pitching prospect, but he comes with a major red flag

The Pittsburgh Pirates have found another pitcher capable of lighting up the radar gun. Whether he can consistently find the strike zone, however, is an entirely different question.

Right-hander Irwin Ramirez was named Pittsburgh's Rookie-Level Pitcher of the Year following an encouraging 2026 campaign that showcased both his considerable upside and the developmental challenges that remain.

At just 19 years old, Ramirez already possesses the kind of arm talent that gets pitching coaches excited. According to Pirates director of coaching and player development Michael Chernow, the 6-foot-3 right-hander throws around 100 mph and generated whiff rates above 50% with his slider and changeup. That's an intriguing combination for a pitcher who signed with Pittsburgh as an international free agent in January 2024.

But there's a significant catch: Ramirez's impressive stuff hasn't translated into consistent results against more advanced competition.

Pirates pitching prospect Irwin Ramirez has electric stuff, but concerning command issues

Ramirez opened the 2026 season with the Florida Complex League Pirates, posting a 3.67 ERA with 23 strikeouts across eight starts. Opposing hitters managed just a .157 batting average against him, earning the young right-hander a promotion to Low-A Bradenton in June.

That's where things became considerably more complicated. In 11 appearances, including nine starts, Ramirez recorded a 6.75 ERA over 41 1/3 innings. He struck out 41 batters but also issued 36 walks, finishing with a troubling 1.98 WHIP.

Those numbers illustrate the difference between possessing elite velocity and knowing how to use it effectively. Throwing 100 mph might overwhelm inexperienced hitters, but that advantage becomes less significant when opposing batters recognize they can simply wait for a pitch they can handle.

To Ramirez's credit, there were encouraging signs down the stretch. He allowed just one run in three of his final four outings, suggesting he was beginning to make adjustments at the higher level. And at 19, there's certainly no reason to write him off based on his first exposure to full-season baseball.

Still, Ramirez represents an interesting test of Pittsburgh's pitching development system. The Pirates have built a reputation for identifying and developing talented arms, with Paul Skenes, Jared Jones, Bubba Chandler and Braxton Ashcraft highlighting the organization's pitching talent.

Pittsburgh's challenge now is ensuring that its next wave of pitching prospects develops the command, consistency and secondary offerings necessary to succeed against increasingly sophisticated hitters.

Ramirez has the physical tools to become another success story. What he doesn't have yet is the polish to make that outcome anything close to guaranteed. His Rookie-Level Pitcher of the Year award recognizes legitimate progress. His struggles at Bradenton serve as a reminder of how much development still lies ahead.

For the Pirates, the real accomplishment won't be discovering another pitcher who throws 100 mph. It'll be teaching him how to consistently get hitters out.
