The Giants brought in Alex Wood to add a lefty arm to the starting rotation. Wood should be familiar to Giants fans from his tenure in Los Angeles with the Dodgers. Most recently he pitched four innings of relief in the 2020 World Series, allowing two hits and no runs with five whiffs.
A quick check of Baseball-Reference shows that his last full season was 2018 when he started 27 games. The year before that he was an All-Star. He just turned 30 years old and has a 3.45 ERA (3.51 FIP) over eight seasons and almost 900 IP (138 GS).
