What happened: The infielder is making the first such stint of his career. Elsewhere, the Cleveland Guardians activated Jose Ramirez from the injured list after his recovery from a June 13 hamate bone procedure. The Philadelphia Phillies are actively evaluating their internal outfield options ahead of the trade deadline.

Why it matters: Witt's absence removes a cornerstone bat from the lineup during a critical stretch of the season. Ramirez's return provides an immediate offensive upgrade for Cleveland. In Philadelphia, managing partner John Middleton and Dave Dombrowski are navigating the trade market to address roster needs despite possessing a thin farm system.

What to watch: The Phillies return to action Friday to host the Yankees following a Thursday off day. Market attention also remains focused on the potential acquisition cost for starter Tarik Skubal.
