What happened: With the trade deadline roughly a month out, several middle-of-the-pack clubs must decide whether to buy or sell. More than a dozen teams sit within six games of a wild-card spot, leaving the Nationals, Marlins and Blue Jays with tricky calls. Each occupies a different point on the contention curve heading into the second half.

Why it matters: Washington leads the majors in runs scored behind James Wood and CJ Abrams, yet remains in year one of a rebuild in an NL East stacked with the Braves, Phillies and Marlins, an argument for patience over chasing a third wild card. Miami, a genuine surprise, has earned a rare window to add controllable talent. Toronto, a year removed from coming two outs shy of a title against the Dodgers, is betting on health and a Vladimir Guerrero Jr. rebound to fuel another Blue Jays push toward October.

What to watch: The deadline is about a month away. Watch whether Miami adds club-controlled pieces to press its window and whether Toronto's offense reverts toward its expected level.
