What happened: The Chicago White Sox acquired Jose Urquidy from the Pittsburgh Pirates on Sunday, while the Boston Red Sox obtained Curtis Mead from the Washington Nationals for Connelly Early. Transactions since May 9 have involved 19 clubs, with Pittsburgh participating in four completed swaps.
Why it matters: The deadline is the season's final point for clubs to trade players on 40-man rosters, putting immediate pressure on roster and postseason planning. Players can still move through outright waivers afterward, but the former August waiver-trade system no longer exists.
By the numbers: Thirteen trades involving 19 clubs were completed from May 9 through July 26. Pittsburgh appeared in four, while the Chicago Cubs and Houston Astros each appeared in two.
What to watch: Further deals can be completed until 6 p.m. ET on Aug. 3. Clubs then turn to waivers and internal roster moves for late-season adjustments.
