Red Sox select RHP Ryan Weber, designate RHP Brandon Brennan

The Red Sox announced they’re selecting the contract of right-hander Ryan Weber. Fellow righty Brandon Brennan has been designated for assignment to open active and 40-man roster space.

Weber makes his return to Boston, where he saw big league action in 2019-20. The sinker-baller pitched to a 4.73 ERA/4.89 FIP in 83 2/3 innings over that time. Weber doesn’t miss many bats, striking out a minuscule 15.3% of opponents with the Red Sox. He’s thrown plenty of strikes and kept the ball on the ground at an above-average clip, though. Weber was outrighted off the roster last offseason and began this year with Triple-A Worcester. He’s made seven appearances (six starts) with Worcester, managing a 4.63 ERA with a 22.4% strikeout rate and solid 6.8% walk rate.

The Sox claimed Brennan off waivers from the Mariners in early May. He spent his first month in the organization at Worcester, tossing 8 1/3 frames of two-run ball. Brennan struck out eleven against five walks at Triple-A, earning him a call-up yesterday. The 29-year-old worked three scoreless innings out of the bullpen in last night’s loss to the Blue Jays. Unfortunately for Brennan, his 42-pitch workload took him out of commission for the next day or two. The Red Sox ultimately decided to bring in a fresher arm in his place.

Boston will have a week to trade Brennan or place him on outright waivers. He still has all three minor league option years remaining, so it wouldn’t be a surprise to see another club bring him in. A former Rule 5 draftee, Brennan has a 4.21 ERA/4.61 SIERA over 57 2/3 MLB innings.
