Brainer Bonaci has been a professional baseball player for just over two years and he doesn’t turn 19 years old until next July, but he is already looking like one of the more exciting young infielders in the Red Sox’ minor-league pipeline.
The 18-year-old shortstop is coming off an impressive showing at the Sox’ fall instructional league in Fort Myers. According to SoxProspects’ Ian Cundall, Bonaci “looked the best of the young shortstops [at fall instructs] and showed a solid blend of instincts and physical ability. He has a plus arm and both his glove and hit tool showed average potential.”
Signed out of Venezuela by Manny Padron and Eddie Romero for $290,000 on his 16th birthday in 2018, Bonaci is starting to get some legitimate attention thanks to what he did this fall.
Had there been a minor-league season in 2020, Bonaci likely would have began the year with the Gulf Coast League Red Sox. Instead, due to the ongoing COVID-19 pandemic, he was limited in what he could do until October, when fall instructs began.
In his only organized action as a minor-leaguer thus far, the 5-foot-10 switch-hitter posted a solid .279/.356/.379 slash line (111 wRC+) to go along with three home runs, 37 RBI, and 18 stolen bases over 61 games played for the Dominican Summer League Red Sox last year.
Because he is still only 18 years old, Bonaci still has plenty of room to grow physically and developmentally. That said, there’s still reason to be excited about his potential, and SoxProspects’ latest prospect rankings reflect that.
Yes, Bonaci is now the No. 14 prospect in Boston’s farm system according to SoxProspects, good for the fifth highest ranking among infielders after Triston Casas, Jeter Downs, Bobby Dalbec, and Nick Yorke.
Going back to April 1, Bonaci was regarded by SoxProspects as the club’s 20th-ranked prospect, so it is clear he is trending in the right direction. And with Dalbec set to graduate from his prospect status next season, it’s safe to assume Bonaci will only continue to rise through the prospect ranks in 2021.
If we look even further ahead, Bonaci will become Rule 5 eligible for the first time in late 2022, so it’s not like he is too far out from garnering 40-man roster consideration as his development continues.
