What happened: On MLB Network's MLB Central, insider Jon Heyman said the chances are "excellent" that left-hander Tarik Skubal is traded, putting the odds at 90 percent. The segment broke down a field of potential suitors: the Cubs, Dodgers, Padres, Phillies, Rays and Brewers.

Why it matters: Skubal is one of the sport's premier starting pitchers, and a move of that caliber would reshape the rotation of any contender that lands him. The breadth of the suitor list — spanning both leagues and several win-now clubs — signals the kind of bidding war that defines a marquee trade-deadline chase.

What to watch: Watch which of the six named clubs moves from interest to a concrete offer, and whether Heyman or other insiders narrow the field as the deadline approaches.
