Wilcox said the win represented the reward for many years of hard work.
"This is all we've ever worked for," he said. "This is what our class came up thinking, that we were going to win it senior year if anything, and we did it. That's all that matters now."
Mehle, in his eight State Tournament appearance in 17 years, said it was rewarding to finally reach the pinnacle.
"It's hard as heck to get this far, just to play for a state championship, and so I'm real proud that our guys had the confidence this time that we were going to put the total package together," he said. "We've been real close several other times. You need a little bit of luck and you need some really competent baseball players and confident baseball players. We had a great group of seniors this year."
The tight finish mirrored the game's beginning as Catholic took a 1-0 lead in the first inning, but Magnolia tied it in the bottom half of the inning. The Irish briefly held a 2-1 lead in the third, before once again the Blue Eagles scored in the bottom half to tie the game 2-2.
Catholic scored seven runs across the fourth, fifth and sixth innings to take a commanding 9-2 lead. That margin, however, proved barely enough to hold off Magnolia's comeback attempt.
McKown finished as the leading Irish hitter with a 3-for-3 performance with three RBI. Thad Jameson finished 2-for-3 with two RBI. For Magnolia, Walton tallied three hits, including two doubles, and two RBI. Keller also finished with three hits, including two doubles, and three RBI. Zack Wilhoit collected two hits and two RBI.
