Here are the cases for the Giants buying — and selling — ahead of Thursday’s trade deadline: The acquisition of Devers in June a clear-cut sign that Posey is in the business of winning now. The same can be said of Chapman’s extension and the signing of Willy Adames.

The Giants enter Sunday’s matchup against the New York Mets at 54–51, sitting 2.5 games behind the final Wild Card spot. In June, they added ex-Red Sox superstar Rafael Devers, but it has yet to pay dividends. Devers himself is hitting just .244 with four home runs and 15 RBIs since arriving in San Francisco.

For Matt Chapman, it shouldn't even be a question which direction the Giants should take heading into the trade deadline.

The Giants are in position to push for the postseason. They've also been awful the past few weeks. Should they go for it or punt?

Kansas City's Seth Lugo was linked to a few teams this deadline season and he was a big part of the rumor mill. However on Sunday night, ESPN's Jeff Passan broke the news that the Royals had signed Lugo to a multiyear extension, taking him off of the board entirely.

The Giants are encouraged to trade Camilo Doval at the MLB trade deadline by rival executives. Maybe that's the reason to hang onto him.

The San Francisco Giants have already made the biggest trade of the season for Rafael Devers. They could make another one in the coming days.

Teams rarely trade closers while in the postseason hunt, and Doval, who’s under club control through 2027, remains a valuable late-inning weapon. However, Sammon and Baggerly noted that “subtracting from the bullpen could allow the Giants to address other pressing roster weaknesses, potentially down the stretch and in future seasons,”.

The Giants have a huge decision to make prior to the trade deadline, and Buster Posey is going to have to figure it out quickly.
