Lucas Giolito
Lucas Giolito is probably the most frequently named starting pitching trade target this deadline. Fortunately, he also meets the criteria for this list as he was named to the All-Star team back in 2019 in addition to his multiple top 10 finishes in Cy Young races.
There are good reasons why every team that needs a starting pitching are looking at Giolito. The White Sox are surefire sellers and Giolito is a pending free agent making a very reasonable, but significant $10.4 million this season. The lack of team control and financial commitment should make the package required to acquire Giolito pretty reasonable for a pitcher of his caliber.
It isn't a mortal lock that he would be as productive as you would think, though. Giolito's Statcast profile is pretty middling after all especially when you look at the batted ball profiles against him. However, his stuff would play well at home in San Francisco and he should remain the top of the Giants' wish list.
Lance Lynn
A surface look at Lance Lynn's numbers does not inspire the most confidence. He currently sports a 6.06 ERA in 19 starts this season and his walk rate is the highest it has been since 2018. He has also been hit pretty hard this season and at 36 years old, it is fair to wonder if age has finally caught up with him.
However, there is cause for optimism with Lynn. He is only two seasons removed from an All-Star season where he posted a 2.69 ERA with 176 strikeouts in 157 innings. One thing that he has kept through his struggles this season is the strikeouts as his 11.05 K/9 rate would be the highest of his career if the season ended today.
To trade for Lynn, the Giants would have to bet on his track record as an underrated starter that knows how to miss bats. San Francisco is really good at getting the most out of pitchers, so it could work out and make Lynn's $18 million club option for 2024 appealing as well.
