formula for lowest 2 in a range

I am formatting an excel sheet to figure golf handicap index.I have all of the formulas in, but I can't figure out a formula to pull the lowest numbers in a range. For example, if I have 7 scores, I would need an average of my 2 lowest 7 differentials. I can get the lowest with the min function, Can you help me with getting more than 1 min.What formula would I use for finding the 2 lowest in (a1:a10)
