What happened: Willson Contreras has been added to the American League All-Star team. He takes the roster spot previously held by Vladimir Guerrero Jr. Additionally, Nick Kurtz will now start at first base for the AL squad.

Why it matters: The transaction brings Willson Contreras into the midsummer classic after he was initially excluded. It also restructures the starting infield to accommodate the personnel shift.

What to watch: The American League will finalize its lineup and rotation ahead of the exhibition.
