*No. 3 North Carolina (4-0) at No. 19 UMBC (1-1) at noon at UMBC Stadium. This is a re-match of last year’s NCAA Tournament first-round game in which the Tar Heels bounced the Retrievers from the postseason with a 15-13 victory. If any team is familiar with North Carolina junior attackman Billy Bitter, it’s UMBC, which was burned by Bitter when he scored eight goals on nine shots last May. Bitter, one of a few preseason favorites to win the Tewaaraton Trophy, ranks second on the team in points and has scored just three goals, but he leads the offense with nine assists. "He’s dangerous any which way you look at it," coach Don Zimmerman said. "One of the reasons he’s distributing the ball is because teams know that they have to slide to him. He’s a good, smart player, and he can find the open man. To North Carolina’s credit, the guys that he’s feeding the ball to are sticking the ball in the goal. Not only is he finding the man, but they’re finishing the shots. He’s certainly as good as there is out there." Don’t be surprised if the Retrievers assign senior Bobby Atwell, their best defenseman, to mark Bitter.

*Towson (0-1) at No. 13 Stony Brook (1-1) at 1 p.m. at LaValle Stadium. A rough start that began with a 13-9 loss to No. 17 Bucknell could get even more challenging with a visit to the Seawolves, who finished second in the America East last season. Stony Brook opened the year with a 21-goal outburst against Siena, but could only muster eight against No. 2 Virginia. Still, Tigers coach Tony Seaman is well aware of what an offense that boasts junior midfielder Kevin Crowley (six goals and five assists) and junior attackman Jordan McBride (8, 2). "We know they’re good," Seaman said. "They’ve got everybody back from last year, and they were pretty successful last year as runner-up in the America East, which is a very good league. And they were picked to be either first or second in that league, depending on who you listened to. So they’re a real good team. Offensively, they’ve got some people who can really score goals." Nine different players scored last Saturday for Towson, but sophomore attackman Matt Lamon is questionable to play due to an emergency appendectomy on Feb. 20.

*No. 17 Bucknell (2-1) at No. 12 Navy (2-2) at 3 p.m. at Navy-Marine Corps Memorial Stadium. Four of the last six contests between these Patriot League rivals have been decided by one goal. The Bison nearly knocked off then-No. 1 Duke before falling in overtime on Feb. 13 and boast a dangerous offense powered by attackmen Tim Brandau (11 goals and two assists), Austin Winter (2, 7) and Mike Danylyshyn (6, 1). "They are, in my view, a better version of last year’s team," Midshipmen coach Richie Meade said of Bucknell, which lost to Navy by one goal in last year’s Patriot League Tournament final. "They’ve got quite a few guys coming back on the offensive end of the field. … They’re very comfortable offensively. In the midfield, they have [Charlie] Streep who everybody knows about, but they have a bunch of other guys who have developed since last year. They’re well-coached, they know what they want to do. I’ve been impressed with their skills and their ability to share the ball offensively." The Bison returned just one starting defenseman and are rotating junior Sam Finnell and freshman Kyle Feeney in the cage, which could be an area that the Midshipmen attack.
