Former All-Star relief pitcher Zack Britton working out for six teams today

Former All-Star closer Zack Britton is hosting a workout for six interested clubs today, tweets Jon Heyman of the New York Post. Anthony DiComo of MLB.com reports that the Mets are one of the six teams in attendance. Ken Rosenthal of The Athletic adds that the Angels, Giants, Dodgers, Cubs and Rangers were also in attendance. The Angels, in particular, have been linked to Britton in recent weeks. Evan Petzold of the Detroit Free Press, meanwhile, writes that the Tigers have had interest in Britton, though it doesn’t seem they attended today’s showcase.

It’s the second time the 35-year-old Britton has thrown for teams this offseason, though the first was more of a leaguewide showcase. That took place back in mid-January, and it stands to reason that today’s workout will offer his most interested suitors a chance to get another look at him as he gears up for a potential signing. That Britton would offer multiple showcases to interested teams isn’t necessarily a surprise, given that he pitched just two-thirds of an inning in 2022 and only 18 1/3 frames in 2021.

Once one of the game’s elite relievers, Britton has seen his star fade in his mid-30s as injuries have begun to take their toll. The lefty had his elbow scoped in March 2021, which cost him the first two months of that season. He returned in June but quickly went down with a hamstring strain that sidelined him another few weeks. The return from that balky hamstring proved similarly short-lived, as an elbow strain again sent him to the injured list.

In Sept. 2021, Britton underwent surgery to address that second elbow issue. The hope was that, like the arthroscopic procedure in March, removing some bone spurs would alleviate the issue. Instead, surgeons determined that Britton’s ulnar collateral ligament had suffered enough damage that a Tommy John surgery was required. He missed almost all of the 2022 season but did make an improbable late-September return. However, that amounted to just three games, during which time Britton walked six of nine batters faced before going back to the injured list yet again. He averaged 92.8 mph on his fastball in that time — nowhere close to the 94.9 mph he averaged during his last healthy season in 2020 (and even further from the 96.9 mph on his sinker at its peak).

That peak, of course, was one for the ages. From 2014-20, Britton notched a superhuman 1.84 ERA in 367 1/3 frames. He punched out 24% of his opponents against a 9.2% walk rate in that time, and Britton’s 76.2% ground-ball rate over that period cemented him as the best ground-ball pitcher since 2002, when batted-ball data of that nature began being carefully tracked. Britton posted a laughable 80% ground-ball rate in 2016 and was at 79.1% in 2015 and 77.2% in 2019 — the three highest single-season marks ever posted by a qualified pitcher.

Whether he can get back to that form in his mid-30s is an open question. Given his diminished velocity and recent elbow woes, it seems like a long shot. But, given that Britton isn’t likely to command more than an incentive-laden deal with a low base salary, there’s plenty of sense in taking a low-cost risk, given the obvious talent and track record of dominance.
