The San Francisco Giants have made no secret about their plans to upgrade a starting rotation that finished 15th in Wins Above Replacement (per Fangraphs) and ninth in FIP in 2020.
Re-signing Kevin Gausman was a strong start, though losing Drew Smyly in free agency was certainly a step backwards. And one they’re looking at potentially offsetting with the veteran addition of left-hander Jon Lester.
According to Jon Morosi of MLB Network, the Giants have shown interest in the five-time All-Star as they look to improve their roster.
