The Pirates are going to promote first base/outfield prospect Esmerlyn Valdez, reports Francys Romero of BeisbolFR. Fellow outfielder Billy Cook will be optioned as the corresponding active roster move, per DK Pittsburgh Sports. Valdez, who will be making his major league debut as soon as he gets into a game, is already on the 40-man roster.
Valdez was an international signing out of the Dominican Republic, securing a $130K bonus. He has since been climbing the minor league ladder with a pretty heavy three-true-outcomes approach. He can draw walks and hit the ball over the fence but can also be vulnerable to strikeouts, though he has shown improvement in terms of the punchouts.
Last year, Valdez split his time between High-A and Double-A, hitting 26 home runs in 529 plate appearances. He drew free passes in 10.6% of those trips to the plate. His 24.6% strikeout rate was a bit high but a notable decrease from the 30.6% rate he posted in Single-A the year prior. He finished 2025 with a combined .286/.376/.520 line and 155 wRC+. He got some help from a .344 batting average on balls in play but it was a strong showing regardless.
The Pirates added him to their 40-man roster in November to keep him out of the Rule 5 draft. Baseball America ranked him the #11 prospect in the system coming into this year, noting that he’s not a strong runner or defender. Here in 2026, he’s been in Triple-A and has been posting really strong results. In 194 plate appearances, he has a huge 17% walk rate and a 21.1% strikeout rate. He has already hit ten home runs. His .253/.381/.506 line leads to a 131 wRC+. BA recently bumped him to #5 in the system.
Pittsburgh opened the year with Oneil Cruz and Bryan Reynolds in two outfield spots. With Spencer Horwitz at first base and Marcell Ozuna the designated hitter most days, Ryan O’Hearn was spending most of his time in an outfield corner. Jake Mangum and a few others also chipped in from time to time. O’Hearn hit the IL a few days ago due to a quad strain, which opened up some playing time. The Bucs already recalled Jhostynxon García and are now adding Valdez into the mix as well.
It’s unclear how the Bucs will divvy up the playing time now. Both García and Valdez are righties, so perhaps there will be some platoon situations at play. Cruz is a lefty and has notable platoon splits in his career but reverse splits in 2026. Reynolds and Mangum are switch hitters with fairly neutral career splits.
Horwitz is a lefty and is usually platooned, so perhaps Valdez will see most of his playing time at first base. The Bucs had been using O’Hearn at first base for a lot of the games starting by a left-handed opponent, with Mangum taking O’Hearn’s spot in the outfield in those instances. Perhaps García and Valdez will combine to pick up O’Hearn’s slack in that dual outfield/first base role. Infielder Jared Triolo, who hits right-handed, recently picked up a few outfield starts but that might be less necessary now.

Valdez is putting up an OPS over 1.000 against lefties the last two seasons. Whatever gets the bat out of Jared Triolo’s hands when a lefty starts games. Valdez should be starting at 1B against LHP, and should take some playing time away from Jake Mangum too.
If your name is Merlyn you should be playing basketball for the Wizards. I guess the Royals would do but only if they have a guy named Arthur somewhere. Even a ball boy would do.
Ozuna DFA incoming?
Hope they arrange the roster so that Valdez gets adequate playing time.
Can’t think they give up on him yet, although they likely should. I do wonder how much his mentorship of Cruz can/will play into the Bucs keeping Ozuna around for as long as possible
If he’s to be kept on the roster, maybe it should be as PH for now.
Cook is being sent down and he hasn’t gotten a lot of playing time, even with O’Hearn out. Triolo getting reps in the OF isn’t the best solution.
My ideal lineup would have DH split between Reynolds, Cruz, and O’Hearn (when healthy), with Valdez and Password getting regular AB.
