What our Post expert thinks about Rays vs. Red Sox

Griffin Jax opened the season in the bullpen before shifting into an opener role, and he’s been effective despite still being limited on pitch count and workload. In his last two starts, he combined to allow just two hits and two walks while keeping opponents scoreless across five innings.

Jake Bennett will make just his second major-league start after impressing in his debut against Houston with five innings of one-run ball. The 25-year-old rookie carried strong command and consistency from Triple-A Worcester into the majors, showing poise with a mix of soft contact and efficient innings.
