Kevin has a knack for playing long matches, just like Querrey who he played twice last year. The first of the two meetings was in Los Angeles and I remember it as if it happened yesterday. A lot of money on Anderson, two super close sets and failing to hedge the bet before the final set where querrey destroyed my guy: anderson's matches
According to that page, Anderson's matches on hard are more likely to last the minimum number of sets (2 or 3 during Grand Slams - e.g. AU Open and US Open). It happened 15 times. But 10 other times more sets were needed.
Mannarino seems to be the type to play many tiebreaks as well. His stats for the three ATP tournaments in Australia since early 2011:
15 matches played
37 sets played: 37
32 sets minimum (15x2 plus two extra sets for the two AU Open matches he played)
9 tie-breaks played (record: 6-3)
This seems to show that Adrian doesn't play as many tight long matches as Kevin, but he averages 0.6 tiebreaks per match, winning two-thirds of these. So if Anderson lets him get close, Mannarino is likely to deliver a heavy punch.
If anything, I would bet Anderson to win straight up here. 2-0 payout is 250% of the SU win payout, but I'd say it's very (50%, maybe 70%) likely that Anderson takes his time here like he usually does. And lets Mannarino win a set. In fact, I very well might put a little something on 2-1 to Kevin at +330.
