The Red Sox are promoting top pitching prospect Luis Perales from High-A Greenville to Double-A Portland, as was first reported by Andrew Parker of Beyond the Monster.
Perales, 21, is coming off one of the best starts of his young career in his last time out against the Greensboro Grasshoppers on Tuesday. The right-hander allowed only one hit and two walks to go along with a season-high 12 strikeouts over five scoreless innings. He threw 81 pitches (49 strikes) and induced 26 swings-and-misses.
On the 2024 campaign as a whole, Perales has posted a 3.42 ERA and 1.98 FIP with 46 strikeouts to 10 walks across seven starts (26 1/3 innings) for Greenville. He missed some time last month due to side soreness but has impressed since returning to the mound, pitching to a 2.11 ERA (1.97 FIP) with 39 punchouts to eight walks over his last five outings (21 1/3 innings) dating back to April 27.
Among 60 pitchers in the South Atlantic League who came into play Wednesday with at least 25 innings under their belts this season, Perales ranked first in strikeouts per nine innings (15.72), strikeout rate (39.7 percent), and swinging-strike rate (20.7 percent), per FanGraphs. He also led the pack in batting average on balls put in play (.474), which suggests that the defense behind him has been lacking at times.
In addition to the gaudy strikeout numbers, Perales has also given up fewer walks and has induced softer contact. As The Boston Globe’s Alex Speier recently noted, Perales has cut down his walk rate from 12.7 percent last year to 8.6 percent this year while elevating his groundball rate from around 30 percent to 47.3 percent.
Standing at 6-foot-1 and 160 pounds, Perales throws from a high three-quarters arm slot and incorporates a medium-to-high leg kick into his delivery. The righty primarily operates with a four-pitch mix that consists of a high-90s fastball that tops out at 98-99 mph, a low-90s cutter, a low-80s changeup, and a mid-80s slider.
Perales, who does not turn 22 until next April, originally signed with the Red Sox for $75,000 as an international free agent coming out of Venezuela in July 2019. Alongside fellow countryman Wikelman Gonzalez, Perales was added to the club’s 40-man roster over the winter to receive protection from the Rule 5 Draft. He is currently regarded by Baseball America as the No. 9 prospect in Boston’s farm system, which ranks third among pitchers in the organization behind fellow righties Gonzalez and Richard Fitts.
In Portland, Perales is slated to join a starting rotation that — for the time being — includes the likes of Gonzalez, Angel Bastardo, Isaac Coffey, Zach Penrod, Helcris Olivarez, and Hunter Dobbins. If any of these arms were to make the jump to Triple-A Worcester to accommodate the addition of Perales, Penrod would seemingly be a prime candidate.
