Martinsburg seemed flummoxed by Huntington's zone defense in the first half and Rogers admitted his players settled for outside shots. The Bulldogs missed 12 of their 13 attempts from beyond the arc in the first half, including a 0-for-5 performance from 6-7 star Donte Grantham.
With Grantham's size on the perimeter, Huntington outrebounded Martinsburg 18-12 in the first half en route to a 5-point lead at intermission.
In the second half, the Bulldogs held a 21-8 edge on the boards.
Grantham, a coveted and uncommitted Division I prospect, finished with a team-high 16 points and game-high 13 rebounds. He had 10 points and nine rebounds in the second half.
"They were switching up some zones a little bit," Rogers said of Huntington. "A couple of times we weren't patient. I thought we started out the game shooting too many 3s."
Martinsburg fell behind by 7 early in the second half and trailed 37-31 with 4:58 left of the third. The Bulldogs closed that period on a 9-2 run and outscored the Highlanders 29-13 over the final 12:58.
The final spurt was keyed by Robinson, who was left open twice as the Highlanders' defense swarmed Grantham in the high post and drifted toward second-leading scorer Jalen Lewis.
"(Robinson) was definitely not one of the two who was one of our targets," Huntington Coach Ronald Hess said. "He hit a couple of big shots there."
Martinsburg will face the winner of today's 11:15 a.m. quarterfinal game between No. 4 Washington (20-5) and No. 5 Parkersburg South (21-4).
Whichever team wins that game will get a Martinsburg club that has won 20 of 24 games by double digits this season.
