What happened: A roster shuffle made a new right-handed arm active for Friday night while pushing Lorenzen off the 40-man roster. The designation starts the formal process for the club to trade, release or outright him.

Why it matters: Late-season pitching moves can change bullpen and depth-chart plans immediately when the incoming arm is available the same day. The transaction also forces a near-term decision on Lorenzen's roster future instead of a standard day-to-day move.

What to watch: Watch for the club's next move on Lorenzen and for how quickly the newly selected right-hander is used.
