Who has had the more impressive AFL? These two guys have been by far the best players there. Hanson's OPS is around is SLUGGING 1.000 because of his 12 homers to go with a batting average close to .400.

Hanson today went 5 IP 1 H 0 R 10 K

I would go Hanson because he a pitcher and I think its more difficult to dominate a very talented league after you have thrown 150 IP in a year but Flowers has been nothing short of remarkable.
