Alcovy's last season in Region 3-AAAA came to an end Wednesday in the region playoffs.
The Tigers (13-12, 8-6) were swept by Whitewater, losing 4-2 in the opener of a doubleheader and 12-2 in the nightcap.
It was the second and third time in five games Alcovy faced the second seed from subregion B with the first meeting going in the win column for the Tigers.
Alcovy beat Whitewater 10-9 in eight innings on April 13 and Wednesday's first game also came down to a close finish.
The Tigers went up 2-0 early after Bowen Braswell's first-inning two-run home run.
The Wildcdats (19-6, 11-3) would go on to tie it before stepping up to the plate in the bottom of the seventh inning.
Whitewater then delivered a two-run game-winning home run, putting itself just one game away from the state playoffs.
"We had more hits than they did but they had that two-run homer that killed us," Alcovy coach Casey Bates said.
Jake Jones was on the mound for Alcovy, and kept the Wildcats at bay, until the seventh inning.
The second game didn't go as well for Alcovy as Whitewater scored three in the second inning and didn't look back.
"We made a couple of errors here and there," Bates said. "It wasn't happening for us that game."
The Tigers outhit Whitewater again, but the hits came in non-scoring situations and throughout the game.
The Wildcats' hits came in key situations, helping them advance.
"Our region is tough," Bates said. "Anybody can beat anybody on any given day."
In the 2013 season Alcovy will move to Region 2-AAAAAA after realignment this summer.
