Font's numbers are weird. Ks are up, walks are down, hr/fb is down. His FIP is a respectable (and career best) 3.91 and even his xFIP is only 4.27, but the results have been awful. BABIP is an absurd .472.
It's a sample size of 11 innings, so most of that data isn't particularly useful beyond some short term trends, but his advanced metrics aren't bad at all this year.
