LONE GROVE — While the Plainview Lady Indians entered Thursday’s Longhorn Invitational tournament as defending champions, the Plainview Indians entered with something to prove.   Both teams got their respective missions off to the best possible start as each team won its opening round game, setting up semifinal contests on Friday night.   Plainview’s Lady Indians will take on Marlow at 4 p.m. while the Indians will meet Lawton Christian at 8:30 p.m.   Girls   Plainview 42 Lone Grove JV 10   The No. 19 Plainview Lady Indians might not have come out strong offensively against the Lone Grove JV squad Thursday morning, but they finished with a flurry.   Plainview led 11-0 after the first quarter, before taking an 11-4 lead into the break.   The Lady Indians offense found a rhythm in the third quarter as they scored 23 points to build a 34-8 lead, before finishing the game off with an 8-2 run in the fourth.   Megan Winchester led the scoring with 13 points for Plainview followed by Reagan Chaney with eight points and Peyton Jones with five points.   Madison Imhof led Lone Grove with eight points.   Boys   Plainview 61 Marlow 44   If there was any question about the basketball fitness of Blake Nowell on Thursday, he gave some resounding answers in the form of thunderous dunks.   Newell’s arial show was just a fraction of the offense Plainview produced, as the Indians rolled past the Marlow Outlaws into the semifinals.   The first quarter was all Plainview as the Indians offense took control early, building a 24-11 lead.   Marlow made things interesting before halftime as the Outlaws got within six points at 30-24, before Plainview took a 35-26 lead into the break.   In the third, the Outlaws once again got close, this time within four points at 42-38, but Plainview held its nerve and built a 47-41 lead going to the fourth.   Down the stretch the Indians outscored the Outlaws 14-3 to win the game.   Brock Parham led the scoring for Plainview with 17 points followed by Cason Dillon with 15 points and Blake Nowell with 12 points.
