Over 21.5 games
Good odds on the over on games here as I see the match being very close between these two players.
Kicker has not played on hard courts, but his win over Clarke in three sets in the first round gives me confidence he can hold his serve here agains Johns who is not an established player.
Johns has some good wins on hard courts but I dont see him blowing past Kicker here and on the opposite hand I dont see Kicker winning in under 22 games.
Take the over.
