Pena scattered eight Forrest base hits, walked one and struck out one for the unblemished Viqueens.
Sarah Pierce swung the hot lumber for the Viqueens, pounding a pair of triples, driving in two teammates, scoring twice, and executing a sacrifice bunt.
The Lady Rockets could not come up with the big hit when they needed to as they left nine runners stranded on base in the ballgame.
After Pena got out of a two-on, two-out jam in the top of the first and retired the side in order in the top of the second in the scoreless game, the usually solid FMS defense shattered in the home half.
The first three Community batters in the inning all reached on FMS errors and two of those, Aliyah Seagraves and Alex Milliken both crossed home plate moments later on RBIs by Dara Ramos and Davie Barnes.
Pena retired FMS 1-2-3 in third, and after Amanda Patterson reached on a leadoff error in the fourth, Pena set down the Lady Rockets in order to end the inning.
Community tacked on another unearned run in the bottom of the fourth to make it 3-0.
Forrest left two runners on base in the fifth and after a one-out triple by Pierce in the bottom of the fifth, Aliyah Seagraves knocked in Pierce with a perfectly executed squeeze bunt.
Once again, the Lady Rockets left two runners stranded in the sixth before Pierce put the game away in the home half of the frame on a two-run triple down the left field line that drove in Pena and Sydney Seagraves, who had both reached base on singles.
Piper Elmore and Kyleah Hengesbach kept hope alive for Forest with base hits in the top of the seventh before the game ended on a fly ball to Haley Reed in right field.
Taylor Patin and Kelsey Darnell went 2-4 for Forrest, and Lainey Mays, Hengesbach, Samantha King, and Elmore all went 1-3.
Mays went all six innings in the circle for FMS, allowing three earned runs on seven hits, while striking out one, walking one, and hitting one Viqueen batter.
