SARASOTA, Florida—The Orioles have traded two of their most experienced relief pitchers, Tanner Scott and Cole Sulser, to the Miami Marlins for 17-year-old Dominican centerfielder Kevin Guerrero, 25-year-old left-handed pitcher Antonio Velez and Miami’s Competitive Balance Round B pick in this summer’s draft.

Scott, who settled his arbitration case for $1.05 million last month, was 9-8 with a 4.73 ERA and one save in five seasons with the Orioles. Last year, the 27-year-old Scott was 5-4 with a 5.17 ERA in 62 games. The left-hander had two stints on the 10-day injured list because of a left knee sprain and had a 9.82 ERA in the second half.

Sulser, who was claimed on waivers from Tampa Bay just after the 2019 season, was 6-9 with a 3.45 ERA and 13 saves in 2020 and 2021. The 32-year-old right-hander was a candidate to close for the Orioles.

Guerrero batted .260 with 11 RBIs in 40 games with the Marlins’ entry in the Dominican Summer League last season.

Velez was 7-2 with a 2.55 ERA in 23 games last season with High-A Beloit and Double-A Pensacola.

The deal opens two spots on the 40-man roster. The Orioles need to add a backup catcher to Robinson Chirinos and could add infielder Chris Owings, who signed a minor league contract.

Right-handers Jorge López and Dillon Tate are contenders to close for the Orioles.

The Orioles have 40 players on their spring training roster.
