A hot-hitting prospect named Franklin has captivated Red Sox Nation this summer. While 2026 has in many ways been about Franklin Arias’ meteoric rise to MLB’s No. 3 prospect, Franklin Primera has also been demolishing pitching everywhere he’s been.
Primera, now Boston’s No. 4 prospect, delivered a career-high seven-RBI performance during a three-hit night in Single-A Salem's 21-4 thumping of Wilson at Carilion Clinic Field on Tuesday night. Across 13 contests this month, the 19-year-old has collected 20 hits and is slashing .444/.590/.800 with his 1.390 OPS leading the Carolina League.
After getting plunked on the left arm in his first plate appearance, Primera responded in the second with his 12th homer of the year and fourth since joining the RidgeYaks. He sliced a hanging breaking ball to right-center in the third, plating a pair before trucking into second. He was back in the RBI column an inning later, notching a run-scoring groundout before clearing the bases in the fifth with a double that stayed just inside the first-base bag.
Equipped with a right-handed swing that has shown an ability to do damage to all fields, Primera has the look of a future impact bat. But it wasn’t always that way. Signed for just $10,000 later on in the 2024 international period, Primera has been a late bloomer.
After showing off a disciplined eye at the dish in his debut campaign last year in the Dominican Summer League, Primera carried those traits over to his first stateside foray in 2026. He decimated Florida Complex League pitching, slashing an otherworldly .427/.549/.718 with eight homers and 29 RBIs in 32 games, walking (22) more than he struck out (13).

Even with the caveat that Statcast technology isn’t available for every game on the Rookie-level circuit, Primera still managed to put 11 balls in play at 100+ mph, including a 111 mph homer on June 19. Only Willson Contreras (four times) and Jarren Duran (twice) have achieved that feat among big league Red Sox in 2026.
Measuring performance relative to levels is an imperfect science. But one way to look at the production is through wRC+ -- Kevin McGonigle, Jac Caglianone and Konnor Griffin were three of the Minors’ top seven performers last year. This season, Primera ranks second in all of Minor League Baseball (min. 200 plate appearances) with a 183 wRC+.

The Red Sox have managed Primera’s workload behind the dish, not having him catch in three consecutive games since earning the bump to Single-A in late June. A well-below-average runner, first base might be his home in the long run and he started there eight times while in the Complex League.
That spot on the diamond would put a bigger emphasis on the bat -- but ultimately, that's Primera's selling tool anyway. He’s still managed to find success at the lower levels despite an alarming ground-ball rate (59.3 percent at Single-A entering Tuesday), which primarily stems from swinging-strike rates that have hovered around just 8 percent for his early career. He’ll have to hone that discerning eye even further as he moves up the ladder but the present results are impossible to ignore.
Primera is the latest young prospect to enjoy a breakout in Boston’s system behind the club’s increased focus on improving bat speed. He also represents the organization’s ability to discover less-heralded gems on the international market -- of the team's new top four prospects, all signed for $525,000 or less within the past four years.
