What happened: Tight playoff races have left some clubs seeking immediate upgrades while others consider moving veterans for future value. Several front offices could add and subtract before the cutoff.

Why it matters: Contenders have one final opportunity to reinforce their rosters through trades. Sellers can turn short-term contracts into prospects, while clubs pursuing both paths must balance the playoff race against longer-term needs.

What to watch: Completed deals and late shifts in club strategy will shape the market through the 6 p.m. ET cutoff.
