Red Sox signed RHP Tayron Guerrero to a mionr league contract with an invitation to spring training.

The 35-year-old hurler hasn’t pitched in the big leagues since the 2019 season. He spent the 2025 campaign toeing the slab for the Chiba Lotte Marines of Japan’s Nippon Professional Baseball where he registered a 3.60 ERA, 1.32 WHIP and a 46/23 K/BB K/BB ratio across 50 frames. He’ll add bullpen depth for the Red Sox.
