MANKATO, Minn. -- A daily review of the hot topics coming out of Minnesota Vikings training camp:

• The Vikings have a day off on Tuesday, and coach Mike Zimmer will use it to meet with his staff and decide which players need more practice snaps and which ones might get less work. It's getting harder and harder to see the team's quarterback competition as anything other than a race between Matt Cassel and Teddy Bridgewater. Cassel and Bridgewater got most of the work in the Vikings' night practice, which was heavy on playbook installation; Cassel again took the first-team snaps, while Bridgewater worked with the second team and Ponder with the third. Cassel hit 5 of his 9 passes and found a wide open Greg Jennings on a nice throw down the right sideline. Bridgewater went 12-for-13, and Ponder went 1-for-2. All three quarterbacks had a dropped pass, which means Bridgewater and Ponder technically didn't miss a receiver all night. But when the Vikings are giving Cassel the work with the starters -- and using much of their remaining time on Bridgewater -- it doesn't say much for Ponder's chances. Bridgewater hit 4 of his 12 completions to running backs, and had to be bailed out by his receivers on a couple throws, but he did a nice job stepping up in the pocket, made a solid throw to Rodney Smith on the run and again connected with Adam Thielen. He's continued to impress.

• Blair Walsh got his first chance to kick during training camp, and made seven of his eight field goal attempts. His lone miss was from 44 yards out, and Walsh finished the session by drilling a 52-yarder.

• First-round pick Anthony Barr showed his speed as a pass-rusher in a sack, so to speak, of Cassel during 11-on-11 work. Barr surged through the middle of the Vikings' line on a blitz, getting to Cassel as the play was blown dead (quarterbacks, of course, aren't allowed to get hit during training camp). He's mostly worked with the second team, but has had a handful of first-team snaps. He might have to get past Audie Cole for the starting strong-side linebacker job early in the season, but Barr's size and speed has the Vikings excited about what they're seeing.

• The Vikings did their first goal-line work on Monday night, and it was easy to see why Zimmer wanted to keep Adrian Peterson out of the session. The Vikings were practicing at "thud" tempo, where defenders initiate contact without taking ballcarriers to the ground, but the drill featured some live hitting, like when Jasper Brinkley drilled Matt Asiata for a loss on the first snap of the drill and the third-string defense hammered undrafted free agent Dominique Williams.

• The evening practice had a special guest: Vikings owner Zygi Wilf, who is in Mankato for a summit with the team's ownership group, watched the session from the top row of Blakeslee Stadium, sitting with general manager Rick Spielman.
