The Pittsburgh Pirates will call up left-handed pitcher Hunter Barco, their No. 4 prospect, from Triple-A Indianapolis. First with the news was Brent Martineau of Action Sports Jax, as in Jacksonville, Florida, where the denizens have a special interest in the career of Barco, a former Florida Gator who was born in Jacksonville. The Pirates have not announced the move or the corresponding move. As Monday is an off day, no official moves will likely be made until Tuesday before they take on the Reds in Cincinnati.
Word is former @BollesBaseball star Hunter Barco got the call to the big leagues today for the Pittsburgh Pirates. Awesome for him.

The Pirates drafted Barco out of the University of Florida in the second round of the 2022 June Amateur Draft. As a six-foot-four, 235-pound hard thrower, the 24-year-old fits the prototype for young pitchers drafted under general manager Ben Cherington. His sinking fastball sits at around 95-96 mph to go with a slider that generates good swing-and-miss and a splitter that serves as his off-speed pitch. He hides the ball well before an unorthodox delivery, making his fastball seem even faster.
“[I] still have all the funkiness [in my delivery] that I’ve always had,” Barco told Dendrick Hendrix of Baseball Prospect Journal. “But in terms of moving better and direction down the mound, [I’ve] definitely gotten better.”
After not giving up an earned run in six outings at Double-A Altoona, Barco was promoted to Indianapolis in May. There, he was 3-1 with a 3.79 ERA and a 1.371 WHIP, while striking out 10 batters per nine innings. Overall, he’s 4-1 with a 2.81 ERA and 1.198 WHIP across the two levels. In three September outings, he’s given up two earned runs in 6 2/3 innings while holding opponents to a .167 average. Barco wasn’t scheduled to join the big time until 2026, but perhaps the Pirates were persuaded by these recent outings.
Barco is just the latest to join the Pirates from their pitching-rich farm system. No. 7 prospect Braxton Ashcraft joined the big club in May, followed by No. 2 prospect Bubba Chandler last month. Both have pitched well. On Saturday, Chandler and Ashcraft combined to toss eight innings of one-hit, shutout ball against the Athletics. They’ve given Barco a high standard to hold up to.
How Barco will be used is unknown. This season, he’s been used both as a starter and out of the bullpen. He’s pitched 99 1/3 innings so far. Judging by how the Pirates have handled Chandler and Ashcraft, don’t expect the Pirates to extend Barco with long outings. A role as a starter or bulk reliever could be in the cards for Barco. Pirates fans have to be excited by what the future holds from the mound. Now if only they would sign some hitters. . .
