What happened: Yahoo's weekly MLB lineup report flags two notable shifts: Bryce Eldridge has arrived in a regular lineup role, and Spencer Horwitz is now hitting in the leadoff spot. The rundown tracks lineup trends across the league and the resulting fallout for fantasy managers.

Why it matters: Lineup-card moves like these reshape playing time and plate-appearance volume, which is what drives day-to-day value for fantasy rosters. A bat moving to leadoff means more trips to the plate over a full week, while a promotion into the everyday lineup signals a club's confidence in a younger hitter. Horwitz had already drawn attention earlier this month before this leadoff change.

What to watch: Watch whether both stick in their new roles over the coming week, since lineup spots can shift quickly with matchups and rest days. Continued production would cement Eldridge's everyday status and keep Horwitz atop the order.
