What happened: Major League Baseball is asking fans which of the game's top sluggers they would want at the plate with the outcome on the line, part of a promotion tied to the league's All-Star balloting. The push comes as fans can cast votes up to five times per day through June 25.

Why it matters: All-Star selections shape the rosters for the midsummer showcase and carry recognition weight for the players who earn the nods. A late surge in fan turnout can swing tight races at several spots before the voting window closes.

What to watch: Watch the position races tighten as the June 25 deadline approaches and the leading vote-getters lock in their spots.
