Bannister doesn't throw over 83 MPH. Brewers did him a huge favor by trying to hit every pitch out of the park. I think they left like 10 men on base through 4 innings.
With a more patient team, Bannister would have given up at least 4 runs in this game probably more. I don't think he's a very good option in fantasy leagues.
