7. Trade-off pieces like Tyler O'Neill, Paul DeJong, and Chris Stratton for assets
Outside of their top three "selling" assets in Montgomery, Hicks, and Flaherty, the Cardinals have a few other names they could get value from.
Tyler O'Neill feels about as good as gone from the Cardinals this deadline. Some team is going to take a flyer on him as a bounce-back candidate for the second half, and he's also under team control through next year.
There are a few contenders out there that need shortstop help, and Paul DeJong has quietly been one of the better shortstops in the game this year. He has a club option for 2024, so the Cardinals can sell that to teams as well, or keep him and explore a deal again in the offseason. I like the idea of clearing a path for Masyn Winn to debut this year, though.
Chris Stratton is a guy I am sure a contender will target as bullpen depth. He's not a high-leverage guy, but he is pretty reliable and teams need as many bullpen arms as they can get for a stretch run.
