In the short term Diego will be the biggest challenge to Arriaga.
After all, Diego is the reigning frontcourt champion and finished
with only 3 less wins than Arriaga in the singles race last season.
And he turns just 27 this month.
Erik needs more experience in the lates but should mature and
be able to compete for titles at that level.
Solozabal has all the tools and is also just 27. If he gets healthy
and has the drive he could be the guy to beat by the time he is 30.
