JOHNSTON - Johnston used a 20-0 run during a decisive second quarter to bury the Marshalltown boys' basketball team under an insurmountable deficit, leaving the Bobcats behind for a 62-43 win in cross-Central Iowa Conference play Friday night.
Johnston (5-5) outscored the Bobcats 22-2 in the second period, with Blake Judkins' floater in the lane providing Marshalltown's only points of the quarter just 31 seconds before the half.
The Bobcats (4-9) led 10-8 after the first frame but never pulled ahead again after Johnston surged to the front.
"In the second quarter they amped up their defense," MHS coach Scott Smith said of the host Dragons. "We've got to get tougher on that end of the floor, plus we were having trouble knocking down shots.
"We didn't match their intensity on defense with our screens and movement on offense. That resulted in a 20-point differential in the quarter. We couldn't get the lid off the basket and we just couldn't stop the bleeding."
Judkins and Blake Gimbel led MHS with 14 points apiece. Austin Kluver, De'Quan McDowell and Connor Johnson each tallied four points, and Austin Lovin made a late 3-pointer for the 'Cats.
Jay Knuth paced Johnston with 12 points, Nick Stitzell had 10 points and Michael Mahanna had eight.
Marshalltown takes a season-long four-game losing skid into Tuesday's road trip to Cedar Falls.
Johnston girls rout MHS
Steph Wilkinson scored 21 points and the Johnston girls' basketball team ran away from Marshalltown for a 57-27 rout in Friday's cross-CIC contest.
The Dragons (4-8) led 28-8 at the half and eventually pulled ahead far enough to induce the running clock in the fourth quarter.
Erin Yocum added 11 points and Rachel Hiners had 10 for Johnston.
Marshalltown was led by Eisha Oden's nine points and 12 rebounds. Amanda Hughes had six points while Samantha Hughes and Lauren Mazour both chipped in with four points.
The Bobcats (3-10) go on the road Tuesday to face Cedar Falls before returning home to host Class 5A No. 1 Mason City next Friday.
