More than a week after acquiring three-time All-Star catcher Adley Rutschman, the Red Sox have completed the blockbuster trade that netted him from the Orioles.
Boston sent minor league outfielder Harold Rivas to Baltimore as the player to be named later in the deal on Wednesday, per announcements from both clubs. That means the trade is now complete, with the Red Sox landing Rutschman, fellow backstop Jake Rogers (who has since been designated for assignment), and cash considerations from the Orioles for catcher Carlos Narvaez, pitching prospects Anthony Eyanson and Kyson Witherspoon, and outfield prospects Enddy Azocar and Rivas.
As noted by MassLive.com’s Chris Cotillo, Rivas was initially rumored to be part of the package going back to Baltimore on August 3 before it was revealed that the fifth piece — following Narvaez, Eyanson, Witherspoon, and Azocar — was a player to be named later when the trade was first announced. Since Rutschman was on the injured list with left wrist inflammation at the time, this suggests the Red Sox and Orioles may have already agreed to Rivas’ inclusion last week but waited until Rutschman was activated by Boston on Tuesday to officially complete the deal.
Rivas, then, switches organizations for the first time in his young career. The 18-year-old was ranked by Baseball America as Boston’s No. 10 prospect after originally signing for $950,000 as a highly touted international free agent out of Venezuela last January. He made a solid first impression in the Dominican Summer League last season, marking his professional debut, before making the jump stateside to the Florida Complex League in 2026.
In 46 games for the FCL Red Sox, Rivas batted .241/.343/.429 with six doubles, four triples, six home runs, 19 RBIs, 42 runs scored, 23 stolen bases, 24 walks, and 52 strikeouts over 198 plate appearances. The right-handed hitter slashed .239/.333/.435 in 159 plate appearances against righties and .250/.385/.406 in 39 plate appearances against lefties.
Among 69 qualified FCL hitters this season, Rivas notably ranked second in speed score (9.5), 14th in isolated power (.188), 17th in wSB (1.1), 22nd in slugging percentage, and 25th in swinging-strike rate (11.7%), according to FanGraphs.
Defensively, Rivas saw almost all of his playing time in the Florida Complex League come in center field. The athletic 6-foot-2, 177-pounder made 43 starts in center for the FCL Red Sox, committing five errors and recording three assists in 309 chances over 318 innings. He also made two starts at DH.
In addition to being ranked as the Red Sox’ No. 10 prospect, Rivas came in at No. 13 on Baseball America’s Top 20 Florida Complex League Prospects for 2026 list. The publication noted that while catcher Franklin Primera and right-hander Sadbiel Delzine “were the stars” of Boston’s FCL affiliate, Rivas “opened plenty of eyes as well.”
“The narrow-framed outfielder has a quick, whippy swing geared for line drives, though some scouts noticed that he was a bit eager to sell out for the kind of power that likely won’t be a part of his game as he moves up the ladder,” Baseball America’s Josh Norris wrote last month. “In fact, Rivas might take away more home runs than he hits. The above-average runner showed excellent instincts and routes in center field and more than convinced scouts that he could play the position at an above-average clip.”
Rivas, who does not turn 19 until next May, is still years away from the majors but nonetheless joins a talented, replenished Orioles farm system. He has been assigned to Baltimore’s FCL affiliate in the interim, though it would not be surprising to see him join Low-A Delmarva for what would be his full-season debut before long.
