The San Francisco Giants have signed left-handed reliever Ryan Borucki to a one-year Major League contract, bolstering their bullpen depth. Borucki pitched for the Pittsburgh Pirates and Toronto Blue Jays last season, going 1-3 with a 4.63 ERA in 39 games. The Giants had to make a 40-man roster move, sliding pitcher Hayden Birdsong to the 60-day injured list as he recovers from Tommy John surgery.

Why it matters

The Giants' left-handed bullpen options have been limited this spring, with Reiver Sanmartin and Sam Hentges both dealing with injuries. The addition of Borucki provides another experienced southpaw to complement Matt Gage and the returning Erik Miller, who is working his way back from an elbow sprain.

The details

Borucki has a career 4.28 ERA in 187 games, including 21 starts, over his five-year MLB career. He has 214 strikeouts and 97 walks in 256.1 innings. The Giants had to make a 40-man roster move to accommodate Borucki, sliding pitcher Hayden Birdsong to the 60-day injured list as he recovers from Tommy John surgery.

  • The Giants announced the signing of Borucki on March 22, 2026.
  • Birdsong is expected to miss the 2026 season after undergoing Tommy John surgery next week.
