Even in a defensive system that occasionally held him hostage on the perimeter, Arizona State freshman center Jordan Bachynski made four athletic blocked shots in a four-minute span in a loss to Arizona in January 2011.

It turned out to be a small taste of a much larger dessert, although Bachynski did not feel it at the time. He remembers that game less as a coming-out party than more of a sudden toss into the deep end.

"I was like a deer in headlights, man," Bachynksi said this week. "I just remember ... not being scared but being, 'What do I do?' Because it was in the system with the matchup zone. I had no idea what I was doing. I was just trying to run around and hope I did pretty well."

Hope no longer applies. Bachynski broke former Arizona center Anthony Cook's Pac-12 career record for blocked shots in the Sun Devils' timely home sweep of the Oregon schools last week -- he has 288, Cook had 278 -- in time for what could be his final career game against the second-ranked Wildcats at Wells Fargo Arena on Friday.

While the 7-foot-2 Bachynski is averaging 12.2 points and 9.1 rebounds in helping Arizona State (18-6, 7-4) put itself in strong position for the NCAA tournament, the blocks have become his calling card. He leads Division I with 107 blocks, 21 more than his nearest competitor and more than 262 Division I programs entering the week's play. He is aiming to break his own conference record of 120 set last season, when he finished just behind NCAA leader Chris Obekpa of St. John's.

Coach Herb Sendek's move from his pet matchup-zone defense to a man-to-man put Bachynski in position to use his frame to block and/or intimidate, and he certainly has made the most of it. Some may ignore numbers, but Bachynski places them squarely in his sights.

"My goal was to lead the nation in blocked shots," he said of 2012-13. "I didn't quite get it last year, so I kept that goal on my bathroom mirror."

Literally on his bathroom mirror. Taped to one corner of the mirror is a list of goals -- some personal stuff, some basketball stuff. Some are kept between he and wife Malia, a former ASU volleyball player who is expecting the couple's first child this summer. But just seeing them is enough.
