What happened: Yandy Diaz and Junior Caminero both moved from Cleveland to Tampa Bay in separate deals years apart. They now face their former club in the American League Championship Series with a World Series berth at stake.

Why it matters: Tampa Bay built middle-order production around a Diaz-Caminero core once praised as among baseball's best trios. Cleveland must now navigate hitters its system once controlled in a short October series.

What to watch: Watch how Cleveland pitches to Diaz and Caminero in early ALCS games.
