The month of May was so inconsistent that the Cubs were once a half game out of 1st place. Then they went on an 8 game losing streak to bring them to a 4th place slot at the end of the month trailing Milwaukee by 4.5 games. On a positive note, the Cubs went 15-12 in May as opposed to 10-11 in April (25-24 overall). Hey, I'd like it to be much better right now but there's still plenty of time left and, it could easily be a lot worse.
There isn't any game that stands out to me as a shoe-in for the best game for May so i'll just include all 15 wins in the poll and let the Cubs nation vote amongst themselves.
