The White Sox will officially call up right-handed pitching prospect Jairo Iriarte on Sunday when rosters expand to 28 players, according to the Tiburones Report and Daniel Alvarez-Montes of El ExtraBase (both links to X). The 22-year-old Iriarte will skip Triple-A Charlotte entirely in making the leap from Double-A right to the verge of his Major League debut. Iriarte is already on the 40-man roster, so the White Sox won’t need to make any other corresponding moves.
MLB Pipeline ranks Iriarte fifth among Chicago’s prospects, while Baseball America isn’t far behind with a seventh-place ranking. The righty was an international signing for the Padres out of his native Venezuela in 2018, and he was sent to the White Sox this past March as part of the trade package San Diego gave up to land Dylan Cease.
Over 126 innings with Birmingham, Iriarte has a 3.71 ERA, 10.7% walk rate, and 22.8% strikeout rate. The latter metric is well below the K-rates Iriarte posted in his previous three seasons, but his grounder rate has continued to move upwards, now up to a 46.7% rate. He has also continued to do a good job at keeping the ball in the park, with seven homers allowed over his 126 frames.
The scouting reports indicate Iriarte has a mid-90s fastball and a mid-to-low 80s slider as his primary two pitches, with a decent changeup that is still something of a work in progress. Both Pipeline and BA aren’t certain he’ll necessarily stick as a starting pitcher, but the White Sox will surely first see what he can do as a starter before considering a future move to the bullpen. Iriarte would seem to have a relief-friendly arsenal already, and he could potentially become a closer if a career as a starter isn’t in the cards.
Moving Iriarte straight to the majors from Double-A is a little unusual, as it wasn’t like the right-hander was so dominant in Birmingham that he was kicking down the door for a call-up. With the White Sox in full rebuild mode as they try to avoid a record-setting season of losing, there may not be much harm in evaluating any promising prospects they have, even if Iriarte just gets a couple of outings to get his feet wet against MLB hitters.
