Tyron Guerrero got five outs in the fifth and sixth innings Thursday against the White Sox and wound up with his first MLB victory since 2019.

What a find Guerrero has been for Boston. In his first MLB action since 2019, he has a 2.45 ERA and a 23/2 K/BB in 18 1/3 innings since being called up in late May. The walk rate is simply astounding. Guerrero has always had a great arm, but he couldn’t establish himself in the majors previously because of control issues. He improved there during his time in Japan, but even so, he still walked nine percent of the batters he faced for Chiba Lotte last year. Right now, he’s at three percent. Guerrero is 35, but if he keeps throwing strikes, he could well help the Red Sox beyond 2026.
