Unfortunately.One year ago at this time, Esteban Mejia’s career was on a very different trajectory. The Dominican right-hander, a 2024 international signing, was coming off of an excellent first season stateside, one in which he flashed both dazzling results — a 2.45 ERA and 11.8 K/9 as an 18-year-old for Low-A Delmarva — and a jaw-dropping repertoire, headlined by a four-seam fastball that touched 102 mph, along with a devastating changeup and gyro-like slider.On MLB Pipeline, he’d skyrocketed from an unranked prospect to #8 in the O’s system. Baseball America went even further, listing him as one of MLB’s 100 best prospects, with BA’s Josh Norris raving, “He produces outings that burrow in your brain and stay there for weeks.”Sure, Mejia walked a few too many hitters, but what teenaged pitcher doesn’t? This kid was a star in the making, the Orioles’ fastest-rising and most electric pitching prospect, and 2026 was going to be his year to shine. As I wrote last October, “If 2025 was the year that Mejia broke out onto the prospect scene, 2026 could be the year that he rises to the very top of it.”Oh, 2025 Paul. How young and naïve you were.Mejia did not, as it turns out, rise to the very top of the prospect scene this year. In fact, when the updated lists are published, he may be nowhere to be found at all. His 2026 season was an unmitigated disaster, one that may have irreversibly wrecked his prospect status and left him scrambling to rebuild his nascent career.Opening the season with a repeat engagement at Delmarva, things went off the rails for Mejia almost immediately. His first start was solid enough — six strikeouts, three walks, and one hit in 4.1 innings at Salem — but in his home debut a week later, he allowed five baserunners and three runs without getting out of the first inning.Mejia was plagued by an inability to throw strikes, which reached a nadir on April 17 in Fredericksburg. In that game, Mejia issued an astounding eight walks — twice as many as he’d ever had in a single outing — in 2.1 innings of work. He threw twice as many balls (42) as strikes (21) and uncorked two wild pitches. In the first inning alone, he walked the first three batters, then plated two runs on a balk and a wild pitch, and walked the next two batters to force home another. Even for a pitcher with a career 5.4 BB/9 rate entering the season, this was a whole new level of wildness.Mejia returned in his next start with a gem — four scoreless innings, eight strikeouts, just one walk — and it seemed like his Fredericksburg outing might’ve been a fluke. But then things continued to unravel. Over his next six starts, Meija struggled to an 8.83 ERA and wa
