Here's another way, stealing @J.M's test list

 test = {{15, 11}, {5, 14}, {2, 13}, {3, 5}, {13, 15}, {6, 10}, {8, 15}, {0, 2},
 {10, 13}, {2, 5}};

 First@Extract[test, test~Reverse~2~Ordering~1]

> 0

Remove `First` to see the whole row

Or probably faster is

 Extract[#1, #2~Ordering~1] & @@ Transpose[test]
