How can I ask about the "winner" of an ongoing match? [closed]
Who is in the lead?
Who is ahead?
Who is (currently) winning?
Who is the front runner? This is applicable to any competitive situation where one wants to know who is ahead of the others (metaphorically speaking, one who is running at the front in a running race).
