San Antonio Spurs at Cleveland Cavaliers (-6.5, 181) 
At this point of the season, the Cleveland Cavaliers and San Antonio Spurs should be hitting their stride in preparation for a title run. Neither has been playing like a championship-caliber team lately, though.
The Cavaliers look to break out of their funk and avoid losing three straight for the first time in a year Sunday when they host a Spurs team trying to get back on track after a lackluster defensive performance.
With the postseason less than two weeks away, Cleveland (61-15) is hoping to secure home-court advantage throughout the playoffs. The Cavs have a 3 1/2-game lead over second-place Boston in the Eastern Conference and a one-game advantage over the West-leading Los Angeles Lakers.
After having a franchise-record 13-game winning streak come to an end with Thursday's 109-101 loss to Washington - the East's worst team - Cleveland suffered a humiliating 116-87 defeat to Orlando on Friday. The Cavs shot 36.9 percent from the field and trailed by as many as 41 as the Magic handed them their most lopsided loss of the season.
"It's embarrassing," said LeBron James, who never found his rhythm, finishing with 26 points on 7-of-20 shooting.
The Cavs have lost back-to-back games for just the second time in 2008-09. They have not dropped three in a row since March 22-29 of last season.
Cleveland has the league's best scoring defense (91.3), but it's been completely out of sync over the last two games.
Pick: San Antonio +6.5
Portland Trail Blazers at Houston Rockets (-4, 186)
Four straight blowout wins have put the Portland Trail Blazers on the verge of clinching a playoff spot. They might have a tough time continuing that run at Houston.
With a chance to secure their first postseason appearance in six years, the Trail Blazers look to end their struggles on the road against the Rockets on Sunday night in a matchup of teams jockeying for position in the Western Conference.
Portland (48-27), a half-game ahead of Houston (48-28) for fourth place in the West, needs a win or a Phoenix loss entering Sunday to make the playoffs for the first time since 2003.
With seven games left, this is an excellent time for the Trail Blazers to be heating up. They've won each of their last four games by at least 20 points, including a 107-72 victory over Oklahoma City on Friday night.
"It just shows that we are growing up," said Portland forward LaMarcus Aldridge, averaging 26.4 points and 10.8 rebounds in his last five games. "I think that this team is coming together. Guys are growing up, guys are getting better and I think this is the perfect time to do it."
Aldridge has scored at least 20 points in three straight games at the Toyota Center, but his performances weren't enough to get Portland a win. The Blazers have dropped nine of their last 10 at Houston, averaging 82.8 points during that stretch.
The Rockets have allowed 91.1 points per game en route to winning 15 of their last 17 at home, including a 98-94 win over the Blazers on Feb. 24.
Pick: Over 186
