Sam Hoadwonic, a Sophomore at the time, was the Riverdale pitcher in '09. They had to beat Beech twice in the championship round (4-2 in Game 1, 9-1 in Game 2), as Beech had put them in the Losers' Bracket with a 6-0 win earlier in the tournament.
Siegel also made that tournament, and Riverdale knocked them out. Oddly enough, it was Siegel who beat Riverdale in the 4-AAA final, sending the Lady Warriors to Soddy.
During the offseason, Albritton worked hard enough to gain the starter's spot from Hoadwonic, who left the team after the 2010 season.
Predictions? I can't see it being anyone other than Beech and Soddy. Having seen most of these teams, I'd say Coffee and Mt. Juliet are probably their biggest threats.
