A Lee Sin 1v1....

So me and my friend were doing a mirror match on lee sin. We were doing it so the first kill was crowned the better lee sin. However, as soon as we started, I spiked to 600 ping and it wouldn't come down. He ended up winning that 1v1. We agreed to rematch since we spiked. In normal ping,(60) I ended up stomping him and beat him twice. He still thinks he won the matchup since he won the first game where I was lagging. Which game do you think should count?
