Who: No. 15 Arizona (6-2) at Marquette Where: Bradley Center, Milwaukee When: Noon Saturday TV: ESPN2 The series: Arizona took a 2-1 lead in the alltime series after a classic second-half run turned a 15-point deficit with 17 minutes left to an 85-75 win last Dec. 12 at McKale Center. But the Wildcats don't have a good history in Milwaukee: They lost 76-62 to Marquette there in 1973-74 and were upset by Oklahoma 60-61 at the Bradley Center in the first round of the 1999 NCAA tournament. Marquette overview: The Golden Eagles aren't exceptionally big, but they are tough and physical. Marcus Jackson, a lightly used reserve last season, anchors the post with greatly improved skills this season. He's a big body at 243 pounds, but also mobile enough to beat defenders to the basket. Steve Novak can play either forward spot, but he's most comfortable on the wing, where he is a difficult three-point threat (55.6 percent) to stop at 6-foot-10. Off-guard Dameon Mason isn't a long-range threat, but he’s a determined driver to the basket and a very good offensive rebounder. Travis Diener not only serves as point guard most of the time, but also has Marquette run many of its plays for him. The scout says: "I think they're physically stronger than they were a year ago. If our guys are not physically tough and smart, they'll get their heads handed to them. When I watch their tapes, it's like the reaction I get when watch Stanford. This is not a game that's going to be for the lighthearted." Who's out: UA: Reports no major injuries. Marquette: Backup point guard Brandon Bell is out indefinitely with an undisclosed medical issue; Diener has been playing on a sprained right foot. Probable starters ARIZONA Shakur Stoudamire Adams Fox Frye MARQUETTE Diener Novak Mason Chapman Jackson KEY PLAYERS Marquette: Diener A key player en route to the 2003 Final Four, Diener has risen to preseason All-American status this season as a senior. He does it all, with a 2.5-1 assist-turnover ratio, 22.1 average points a game and 46.3-percent three-point shooting. Arizona: Mustafa Shakur The Wildcats' point guard has a prime opportunity to answer questions about his aggressiveness, ability to penetrate, and shooting. He has struggled to outplay point guards such as Virginia's Sean Singletary, Wyoming's Jay Straight and Wake Forest's Chris Paul. SIDELINES So far, it's been a good week for freshman forward Bret Brielmaier. Not only was he awarded a scholarship for the spring semester, but he also gets to play today's game only five hours from his Mankato, Minn., home at a time when he is beginning to collect quality minutes. Ironically, though, it wasn't easy for him to secure tickets for all his friends and family. Players commonly trade their open passes for road games to teammates who live nearby, but even though Brielmaier and redshirting freshman Kirk Walters are the only UA players from the Midwest, trades weren't easy to come by. "A lot of guys do have people going," Brielmaier said. He's still two years removed from arriving at UA, but Houston point guard Nic Wise is off to a good start at his new school, Kingwood, this season. He was named USA Today's national prep player of the week on Monday after earning MVP awards in two tournaments. Kingwood, alma mater of UA assistant coach Josh Pastner, entered the week 16-0.
