What happened: The Phillies are targeting impact bats like Bryson Stott or Alec Bohm as the Aug. 3 trade deadline approaches, while the Mariners are listening on offers for Luis Castillo and Emerson Hancock, per The Athletic's Ken Rosenthal and Chris Sammon. Catchers are drawing heavy interest league-wide, with the Orioles fielding offers for Adley Rutschman and the Rockies' Hunter Goodman also a target.

Why it matters: A thin catcher market has contenders weighing steep prices for upgrades behind the plate, with Baltimore ready to turn to rookie Samuel Basallo if Rutschman is dealt. The Phillies, at 50-47 and on a two-game skid, need lineup help to hold position in a tight NL race. Seattle could use Castillo and Hancock as trade chips to address other needs before the deadline.

What to watch: Yankees and Phillies open a series in Philadelphia tonight, with first pitch still to come. Deadline activity is expected to accelerate over the next 10 days.
