Red Sox prospect Allan Castro takes another step forward in first season stateside

Allan Castro can no longer be called the reigning Red Sox Latin Program Position Player of the Year. That distinction now falls to infielder/outfielder Andy Lugo, who received the honor on Monday.

Castro, however, put together a strong first season in the United States after being named the organization’s Latin Program Position Player of the Year in 2021.

Following a 2021 campaign in which he posted a .756 OPS in the Dominican Summer League, Castro made the jump to the Florida Complex League for the start of the 2022 season. In 39 games with Boston’s rookie-level affiliate in Fort Myers, the switch-hitter slashed a respectable .279/.355/.451 with four doubles, four triples, three home runs, 17 RBIs, 19 runs scored, eight stolen bases, 13 walks, and 32 strikeouts over 141 plate appearances.

Though he may have been overshadowed by fellow outfielder Miguel Bleis, Castro still ranked 11th in batting average, 26th in on-base percentage, eighth in slugging percentage, ninth in OPS (.805), 11th in isolated power (.172), 13th in speed score (7.8), and 11th in wRC+ (122) among FCL hitters who made at least 140 trips to the plate this season, per FanGraphs.

Not long after the Florida Complex League season came to a close, Castro and several other Red Sox minor-leaguers earned a promotion to Low-A Salem. He registered just one hit in his first five games with Salem but ended the year by going 5-for-18 (.278) with a double, a triple, four RBIs, and five runs scored in his final five games.

“Castro took a significant step forward this season,” Red Sox assistant general manager Eddie Romero told BloggingtheRedSox.com via email. “He’s continued to grow and gained a lot of strength. Additionally, he found ways to make his swing more efficient and started using the whole field more often.”

Between the two affiliates, Castro logged 232 1/3 innings in left field, 84 innings in center field, and 24 innings in right field. The 6-foot-1, 170-pounder recorded four outfield assists and committed just one error all year.

“His athleticism is starting to show itself more on the field,” Romero said. “He is sort of a sleeper prospect who we expect will do more things in 2023.”

Castro, 19, is currently regarded by SoxProspects.com as the No. 53 prospect in Boston’s farm system. The Red Sox originally signed the native Dominican for $100,000 as an international free-agent coming out of Santo Domingo in July 2019.

At that time, Castro was a middle infielder, but he has since made the transition to the outfield and figures to stick there moving forward. Taking into account that he does not turn 20 until next May, Castro is projected by SoxProspects.com to return to Salem for the start of the 2023 season.

Who is Red Sox prospect Allan Castro? Get to know the organization’s 2021 Latin Program Position Player of the Year

Red Sox outfield prospect Allan Castro comes into the 2022 season fresh off being recognized as the organization’s Latin Program Position Player of the Year in 2021.

Castro, 18, was originally signed by the Sox as a middle infielder coming out of the Dominican Republic in July 2019. The Santo Domingo native received a signing bonus of $100,000, but has since made the move to the outfield.

After the start of his professional career was pushed back on account of the COVID-19 pandemic, Castro made his pro debut in the Dominican Summer League last year. Upon being assigned to the DSL Red Sox Red affiliate in July, the switch-hitting outfielder proceeded to bat .232/.335/.421 (110 wRC+) to go along with eight doubles, seven triples, three home runs, 19 RBIs, 24 runs scored, three stolen bases, 21 walks, and 43 strikeouts over 46 games spanning 194 plate appearances.

Among all DSL hitters who made at least 190 trips to the plate last season, Castro ranked tied for first in triples, 28th in slugging percentage, and 13th in isolated power (.189), per FanGraphs.

Defensively, Castro saw playing time at all three outfield positions in 2021. The 6-foot-1, 170 pounder logged 95 innings in left field, 32 innings in center, and 175 1/3 innings in right while recording a total of six outfield assists and turning a total of two double plays.

Back in September, SoxProspects.com’s director of scouting Ian Cundall identified Castro as “one of the Red Sox’ most promising hitters in the DSL, showing the potential to hit for average and power.”

“He has some swing-and-miss in his game, but could get to above-average raw power eventually and an average defensive profile in right field, including a potential above-average arm,” Cundall wrote. “Scouts identified Castro as having one of the best pure bats in the Red Sox’ DSL program and as one to watch when he makes the jump stateside.”  

As Cundall alluded to, Castro is slated to begin the 2022 minor-league season in the rookie-level Florida Complex League. Red Sox assistant general manager Eddie Romero indicated as much in a recent email exchange with BloggingtheRedSox.com.

“Regarding Castro, his career was delayed by the pandemic lost season, and he was really standing out from the offensive end until he tired later in the DSL summer,” wrote Romero. “Encouraging to see a position change to the outfield not affect him, and he ended up with a good range of extra-base hits. We have a talented group of outfielders expected to play in the FCL, and he’ll be in the mix for priority at-bats within that group.”

Castro, who turns 19 in May, is not currently regarded by any major publication as one of the top prospects in Boston’s farm system. Given that he still has room to grow and develop, though, it would not be surprising to see Castro gain some notoriety and rise up the rankings a bit this summer if he impresses in the FCL.
