What to expect from Red Sox outfield prospect Armando Sierra heading into 2022 season

It was exactly 14 months ago Tuesday when the Red Sox signed outfielder Armando Sierra for $150,000 as an international free agent out of the Dominican Republic.

Although he was not the headliner of Boston’s 2021 international signing class (hello, Miguel Bleis), Sierra still received some attention from evaluators within the industry.

Last April, Baseball America’s Ben Badler identified Sierra as a potential sleeper prospect within the Sox’ international ranks, noting that the then-17-year-old had “an advanced approach to hitting for his age” as well as the ability to hit for power.

As a follow-up to that, Red Sox assistant general manager Eddie Romero all but confirmed Badler’s observations in an email exchange with BloggingtheRedSox.com.

“Armando was a player we scouted later on in his signing year. After scouting him a few times, he stood out for his strong frame and his power,” Romero said at the time. “As we continued to see him, it became apparent that not only did he have above average power for his signing class, but he also was developing a stronger approach.”

In the months following his signing, Sierra continued to work out at the Sox’ Dominican academy in El Toro before making his professional debut in the Dominican Summer League last July.

Across 53 games for the club’s DSL Blue affiliate, the young right-handed hitter batted a respectable .284/.373/.379 (117 wRC+) to go along with 10 doubles, two home runs, 35 RBIs, 24 runs scored, 21 walks, and 41 strikeouts over 193 plate appearances.

Against left-handed pitching, Sierra slashed .296/.424/.370. Against right-handed pitching, he slashed .284/.365/.383 with both of his home runs and 33 of his 35 runs driven in.

Among all Dominican Summer League hitters who made at least 190 trips to the plate last year, Sierra ranked 27th in batting average, 48th in on-base percentage and slugging percentage, 51st in OPS (.752), and 54th in wRC+, per FanGraphs.

Defensively, Sierra was labeled as a corner infielder even before signing with Boston. In his introductory course to pro ball, the 6-foot-2, 189 pounder logged 95 innings in left field and 115 innings in right while recording a total of two outfield assists. He also appeared in eight games (seven starts) as a first baseman.

Shortly before the 2021 DSL summer came to a close last fall, SoxProspects.com’s director of scouting Ian Cundall wrote in September that Sierra’s “power potential is impressive. He is a below-average athlete and does not project to add much defensive value, but he has big-time raw power. He gets his whole body into his swing, but there are significant questions with his hit tool that could limit his power utility against more advanced pitching.” 

Sierra, who turned 18 in January, is not regarded by any major publication as one of the top prospects in Boston’s farm system. Given his age, the Sabana Grande de Palenque presumably still has room to grow physically and as a baseball player.

SoxProspects.com projects that Sierra will return to the Dominican Summer League for the start of the 2022 minor-league season. That being said, a promotion to the Florida Complex League later in the year certainly seems plausible.
