Headlined by the likes of Triston Casas, Marcelo Mayer, and Nick Yorke, the prospect who rounded out the list at No. 51 was right-hander Reidis Sena.
Sena, who turns 21 next month, originally signed with Boston as an international free agent out of the Dominican Republic for just $10,000 in December 2018.
After making his professional debut in the Dominican Summer League in 2019, Sena was unable to pitch at the organizational level in 2020 since the minor-league season was cancelled as a result of the COVID-19 pandemic.
The young righty instead picked up where he left off last year by spending the entirety of the 2021 campaign in the rookie-level Florida Complex League. He made his season debut on July 24 and made a total of nine appearances (three starts) for the FCL Red Sox.
In those nine outings that spanned anywhere from one to four innings in length, Sena posted a 3.22 ERA and 3.83 FIP to go along with 31 strikeouts to 13 walks over 22 1/3 innings of work.
Among all FCL pitchers who threw at least 20 innings last year, the 20-year-old ranked 21st in strikeouts per nine innings (12.49), 23rd in strikeout rate (32.3%), 21st in swinging strike rate (33.7%), 29th in FIP, and 26th in xFIP (3.99), per FanGraphs.
With a listed height and weight of 5-foot-10 and 160 pounds, there is not much else available on Sena besides what FanGraphs’ Kevin Goldstein and Tess Taruskin have on him.
“Sena is pretty raw for a pitching prospect who will be 21 in 2022,” they wrote. “He has huge arm strength, sitting 95 mph on the complex last year, and he makes very heavy use of that fastball. His slider has plus raw spin but Sena throws his heater 85% of the time right now, suggesting he and the Sox are just trying to get him to throw a viable rate of strikes more than anything else. He walked over five hitters per nine innings in 2021. If things click for him, he’ll move very quickly.”
As Goldstein and Taruskin indicated, Sena does need to work on his command considering the fact he averaged more than five walks per nine innings and walked more than 13% of the batters he faced last year.
That being said, there does seem to be some intrigue with Sena based off his current arsenal that consists of a high-octane fastball and slider. It will be interesting to see if the Red Sox view the Neiba native as a potential starter or reliever in the long-term.
On that note, though, Sena is projected by SoxProspects.com to begin the 2022 season in Low-A Salem’s starting rotation. He will have the opportunity to rise through Boston’s prospect ranks beginning in April.
