In the final game of the night, the Mavs look to maintain home-court advantage with a second straight win over the visiting Trail Blazers. Jason Kidd had a season-high 24 points to lead Dallas in Game 1, but can the 38-year-old do it again tonight (9:30 p.m., TNT)?

While Vancouver added depth in the offseason, the Blackhawks lost 10 players from their Cup-winning team and haven't looked the same all year. If they want to keep their season alive, they will have to be physical and put the pressure on Canucks netminder Roberto Luongo (8 p.m., Versus). ... After losing Game 1 against the Sharks 3-2, the Kings evened up the score with a 4-0 victory in San Jose on Sunday. The Kings will get back Jarret Stoll tonight when the series heads to L.A.

Down in Florida, the Pirates are hoping to add to their impressive 7-3 road record with a win over the Marlins.

The AL Central-leading Indians look to stretch their four-game win streak with a victory in Kansas City.

The NL-best Rockies host the Giants, who whooped 'em 8-1 behind a great start from Tim Lincecum on Monday night.
