Boston’s among the teams keeping an eye on*Royals*closer*Kelvin Herrera, according to*Nick Cafardo of the Boston Globe. If acquired, the 28-year-old would return to a setup role with the*Red Sox, thanks to the presence of closer*Craig Kimbrel, and would further bolster a late-game mix that also includes*Joe Kelly*and*Matt Barnes. Herrera, who’s in his last year of team control and making $7.94MM, has allowed just two earned runs and hasn’t issued a walk in 22 2/3 innings this season.
