The Red Sox announced this afternoon that they’ve designated left-hander Sean Newcomb for assignment. The move makes room on the active roster for right-hander Luis Guerrero to be recalled from Triple-A.
Newcomb, 32 next month, is a former first-round pick who was selected 15th overall by the Angels back in 2014. He was swapped to Atlanta in the Andrelton Simmons trade prior to his MLB debut and spent parts of six seasons with the Braves from 2017 to 2022. During that time, he pitched to a league average 4.25 ERA in 144 appearances (57 starts) with a near-matching 4.27 FIP. That overall number doesn’t tell the full story, however, as Newcomb was actually an above-average pitched (110 ERA+) over his first three years in the majors. Things took a turn for the worse after that, however, and by the end of the 2022 season he had been cut by the Braves and had a 7.45 ERA with a 5.57 FIP over his 73 2/3 innings of work in the majors from 2020 to 2022. He spent the following two seasons in Oakland with a roughly average 4.32 ERA despite shoddy peripherals that were more or less in line with his numbers during his previous struggles.
Newcomb’s future was filled with uncertainty entering Spring Training this winter. He has signed a minor league deal with the Red Sox over the winter, but the club had a loaded pitching staff and Newcomb hadn’t exactly shown much at the big league level in recent years. Fortunately for the soon to be 32-year-old, the Red Sox suffered a number of injuries throughout the spring. That, in conjunction with an impressive Spring Training, was enough to get Newcomb an opportunity to break camp not just with Boston, but as a member of the starting rotation while players like Lucas Giolito, Kutter Crawford, and Brayan Bello began the season on the IL.
Newcomb’s five starts with Boston over the season’s first month were something of a mixed bag. The southpaw completed the fifth inning just once in those outings and surrendered a 4.43 ERA overall, but his peripherals looked quite strong as he struck out 25.7% of his opponents while walking 10.5%. He got bumped from the club’s rotation as other pitchers started to get healthy, but remained on the roster as a long relief option and excelled in that role as well, with a 3.06 ERA and 3.81 FIP in 17 2/3 innings of work across six relief outings.
In all, the lefty finishes his time with the Red Sox with a 3.83 ERA and 3.28 FIP across 40 innings of work. It’s a solid track record, and it would hardly be a surprise to see a pitching-needy club scoop the southpaw up either via trade or the waiver wire in the coming days given his previous pedigree and more recent success in the majors this year. The Red Sox will have one week to either trade Newcomb or attempt to pass him through waivers. Should he clear waivers, they could attempt to outright him to the minors as non-roster depth but he would have the opportunity to reject that assignment.
As for Guerrero, the right-hander has yet to give up an earned run in 14 innings of work at the major league level across the past two seasons. He’s rode the shuttle between Triple-A and the majors frequently for the Red Sox in recent years due to the fact that he has options remaining, but has yet to get an extended audition at the big league level. It’s possible his opportunity is now, although it must be noted that the Red Sox have a number of hurlers on the injured list whose activation will eventually require someone to be sent down to the minors or otherwise removed from the roster.
