The D-backs have signed on a one-year deal for 2020 with a club option for '21 with free-agent pitcher Junior Guerra, according to multiple reports. Nick Piecoro of the Arizona Republic reports the deal is for $2.55 million for 2020 with a $100,000 buyout on the option.

Guerra, who is in his first year of arbitration eligibility, was non-tendered by the Brewers on Monday. The 35-year-old has three years of arbitration eligibility remaining.

Guerra had a 3.55 ERA in 83 2/3 innings out of the bullpen for the Brewers this past season. The relief role seemed to suit him, after he posted a 4.43 ERA across 2017-18, pitching predominantly as a starter.

The D-backs had a 4.26 bullpen ERA in 2019, which ranked 12th in the Majors.
