There were some rumblings that Kirby could give Sonic some trouble based on the puffball's unexpected run in 2008. It was 50/50 for the first minute, but then Sonic established control of the match. It certainly wasn't a dominant win, but it was never in doubt beyond the early moments. Kirby also preserved his streak of getting 45% or more in all of his one-on-one losses.
