Giants president of baseball operations Buster Posey made it clear on Tuesday that he has no plans to entertain trade offers for homegrown ace Logan Webb. But he acknowledged that he will be open to potential deals for other Giants, including high-priced veterans like Matt Chapman, Willy Adames and Rafael Devers. “I think we'll leave all options on the table,” Posey said before the Giants’ 3-1 series-opening win over the A’s at Oracle Park. “The way things are trending now, I’d say that we've got to remain open to seeing what best ways we can try to improve the club.” The Giants were expected to be in win-now mode after making big commitments to Chapman, Adames and Devers, who are owed a combined $451 million after this season. But the trio has underperformed to varying degrees this year, which is a major reason why San Francisco remains 14 games under .500 at 32-46. Moving any of their big three would be a tall task for the Giants, who would likely have to pay down some of those contracts or be willing to attach young prospects to generate serious trade interest from other teams. Chapman and Adames also have full no-trade clauses, though Posey said he has not spoken with either of them about whether they’d be willing to waive them under certain scenarios. San Francisco should have an easier time finding takers for impending free agents like second baseman Luis Arraez, left-hander Robbie Ray and right-hander Tyler Mahle, who is expected to come off the 15-day injured list and rejoin the rotation on Wednesday. The Giants got a bit of a scare when Arraez departed Tuesday’s game in the fifth after fouling a ball off his right foot in the bottom of the first, but X-rays came back clean. Arraez is considered day to day; if he can stay healthy, he could be the Giants’ best trade chip, as he’s batting .321 with an .803 OPS over 75 games.
