Roosevelt will contend against a Marina team that Luth said has been the "most explosive team I've ever coached."
Junior Tera Blanco is not only the team's ace pitcher, but the team batting leader (.425 average), as well. On the mound, Blanco sports a 24-3 record with 14 shutouts. In 176 innings pitched, she has struck out 214 and has an earned-run average of 0.64.
Other top Vikings offensively are sophomore first baseman Emili Olague (.416 avg.), senior third baseman Samantha Agamaite (.302) and sophomore shortstop Sydney McCollum (.358).
Marina won the Sunset League title for the first time since 2010.
"I'm very happy for the team," Luth said. "It's been a true team effort. Great pitching, good defense and offense."
Marina is seeking its first Southern Section softball title since the school won back-to-back crowns in 1994-95.

Edison's playoff hopes start in Moreno Valley against a Valley View team that finished second in the Inland Valley League.
"We are really excited to begin the final leg of our season," said first-year Edison Coach Kim Ensey whose Chargers finished second in the Sunset League. "There are some really great games lined up for this week. I expect nothing less from our matchup."
Edison's offense features several players who have starred at the plate. Among the leaders are seniors Carissa Sherman (.447 avg.) and Karley Wester (.416), sophomore Reis Birkett who has driven in 37 runs, junior Liz Talataina with seven home runs, and sophomore Ali Wester whose base running skills have led to 20 stolen bases.
"I am fully confident in how we are playing right now," Ensey said. "My girls are fighters and no matter the situation, they are going to fight till the end."
Valley View has a team batting average of .300. Six Eagles have 23 or more hits for the season led by senior Dani Melendez and Carissa Terry with 26 and 25, respectively.
