Six-run rally puts Rice ahead 8-2 in fourth
Seastrunk jumped on a hanging curveball from reliever James Allen and spanked it deep into the woods over the right-field wall to spark the fourth-inning rally.
Earlier, the Owls had chased Kansas State starter Thomas Rooke with an infield hit by Michael Fuda and Chad Mozingo's walk.
After the pitching change, Rice scored runs on a throwing error by KSU third baseman Jason King and RBI singles by Brock Holt and Rick Hague.
The Owls are receiving solid relief help from freshman reliever Matthew Reckling, whose grandfather is the namesake for the ballpark where the tournament is taking place.
Most important of all, the Owls have ace pitcher Ryan Berry ready for relief if needed.
