Don't have plans this weekend? Here are 10 can't-miss series:

1. No. 11 Texas A&M vs./at No. 5 Texas
By the numbers:
A&M: 37-16, 18-6 Big 12, RPI No. 11
UT: 38-12, 17-7 Big 12, RPI No. 10
There is no bigger matchup this weekend. Oh who am I fooling, there may be no bigger matchup of any season. This rivalry is as intense as it gets. The Thursday matchup will take place at Olsen Field, before moving over to Disch-Falk Field at UT for Friday and Saturday. The fact that they are both highly ranked and battling for national seed status is just gravy for this smorgasbord. Key matchup: A&M's Nick Fleece and Joaquin Hinojosa vs. UT's Corey Knebel and Hoby Milner. It's obvious that the strength of each team has been the lock-down starting pitching that each has displayed. With talents like John Stilson, Michael Wacha and Ross Stripling going up against Taylor Jungmann, Sam Stafford and Cole Green, these rotations should be fit for an instructional video. But watch for the key relievers here. Fleece and Hinojosa are both seniors, while Knebel is a frosh and Milner is a sophomore. If those two Greenhorns get nervous feet in this high-stakes rivalry, look for the Aggies to come out on top, thus winning the Big 12.

2. No. 1 Virginia at No. 13 North Carolina
UVa.: 45-6, 22-5 ACC, RPI No. 2
UNC: 41-12, 17-10 ACC, RPI No. 3
Could the Cavaliers actually lose a weekend series this year? Probably not, although their fate is mostly sealed, they'll be a No. 1 seed, play at home and be expected to reach Omaha. So don't be shocked to see a letdown here. And Carolina will be hungry for a defining weekend that could cement its national seed status since its RPI is surprisingly high (though I'm not sold that UNC really deserves it, but that's for another day's rant). Let's see how the Tar Heels respond as the white-hot spotlights shines down on them. Key matchup: Carolina working counts vs. Virginia's pinpoint pitching. The Tar Heels' only chance will be if they can work some deep counts from a staff that normally doesn't go into deep counts. The Heels are second in the ACC with 284 walks on the season. As you know, Virginia gives away free passes about as often as Ebenezer Scrooge gave away charity, just 114 in 51 games. If UNC can make the Wahoos labor a little more than usual, it's bully for them.

3. No. 15 Clemson at No. 6 Florida State
CU: 37-16, 15-12 ACC, RPI No. 9
FSU: 39-13, 18-9 ACC, RPI No. 4
The Tigers have grown teeth again and enter the weekend matchup at Dick Howser Stadium on a 17-3 spree since tax day. In fact, they've shot up to within three games of the Noles in the Atlantic Division. Now, I'm not saying they'll sweep the weekend in Tallahassee, but this is an experienced team that Jack Leggett takes into the lion's den, and they are looking to get into national seed discussion. FSU just wants to stay there. Motivation points to CU. Key matchup: Sean Gilmartin and Brian Busch vs. the left-handed heavy Tigers. The plum & orange has famously struggled against good left-handed pitching recently, and that's what starters Gilmartin and Busch offer on the bump. If they can establish some consistent offense against them and string together some hits, this weekend could be a boon to their postseason at-home hopes.

4. No. 20 Rice at No. 17 Southern Mississippi
Rice: 36-17, 14-7 CUSA, RPI No. 12
USM: 37-13, 15-6 CUSA, RPI No. 16
Yes, you're reading this right, the Owls might not win the Conference USA title. If the Eagles can take this series, it will be just the second time since it arrived from the WAC in 2006 that the name Rice won't appear at the top of the standings. But the bigger picture of this weekend is that the winner of this series puts itself in prime position to be a regional host. USM saw its RPI ranking, right or not, jump from 17 to 10 this week. Key matchup: USM's Collin Cargill vs. the Rice order Owls coach Wayne Graham told me last week that the key to his team is that they have swung the bats better, particularly later in games. Cargill is 6-3 with a 1.24 ERA and eight saves and is a huge key to whether the bats that surround Anthony Rendon will be effective or not. Cargill has given up just five earned runs in 36 innings. FYI, Rendon leads the nation with a head-slapping 72 walks this year.

5. California at No. 21 UCLA
Cal: 28-16, 12-9 Pac 10, RPI No. 34
UCLA: 29-19. 14-7 Pac 10, RPI No. 47
It's bizarre to think that the Bruins have been one of the best teams in the country on Saturdays and Sundays, going 11-3 in their last 14 weekend games. If only they could get off to great starts on Fridays, this team would be downright scary again. The last three weeks has seen the Bears go a tad on the cold side, sporting a 4-7 mark in that span, though their RPI is pretty strong. The Bruins still need a serious RPI boost and could get it here with a few Ws. It didn't help that a power outage ruined their chance at a win over Fullerton on Tuesday. Key matchup: Cal's Erik Johnson vs. UCLA's offense Since we can go ahead and mark down a W for Trevor Bauer's Saturday start -- he's thrown six straight complete games -- that makes Friday's showdown such a key game. The Bruins have gotten great pitching from Gerrit Cole, but it's their lack of punch on offense that has been their downfall on Fridays. Johnson has given up just six hits in his past 15 innings of work.

6. Arizona at No. 25 Stanford
UA: 32-17, 11-10 Pac 10, RPI No. 29
SU: 28-18, 10-11 Pac 10, RPI No. 23
These two teams are pretty identical on the field and on the stat sheet, as witnessed by their close proximity in the RPI, the Pac 10 standings, pitching staffs and batting orders. The two teams have the top two offenses in the conference with the Cats hitting .326 and the Trees hitting .305. But keep in mind that the Cardinal have played a much tougher slate and should be able to handle the step up. Arizona is also just 8-11 in road games this season. Yep, we can do the math.

7. Florida Atlantic at Florida International FAU: 31-20, 16-11 SBC, RPI No. 56
FIU: 35-16-1, 18-8-1 SBC, RPI No. 32
Obviously this is a big, underrated rivalry and just like last season, these two teams go into their showdown weekend with NCAA bids in their sights. In the last weekend of 2010, FAU knocked the Panthers out of at-large consideration (before FIU rebounded and went on to win the Sun Belt tournament). This time, it's the Panthers who are sitting pretty for a bid to the Big Dance and can send the Owls into golf club mode for the summer. Although FAU's win over Miami on Tuesday was a much-needed positive.

8. Oklahoma State at Texas Tech
OSU: 33-19, 13-10 Big 12, RPI No. 28
TTU: 31-22, 10-14 Big 12, RPI No. 41
This one has big-time ramifications in all directions. At the top of the food chain, the Cowboys have a chance to move past Oklahoma (a series they won in Big 12 play) and into the coveted third slot in the Big 12. That would allow them to avoid the No. 1 team in Oklahoma City next week. Of course it may be faint, but with a sweep here and a good showing at Bricktown, the Pokes have an outside shot at a home regional as well. At the bottom of the food chain, Tech is trying to avoid getting knocked out of the top eight of the conference (the Raiders are seventh right now) and would also love to improve that RPI to inside the top-40.

9. Creighton at Missouri State
CU: 36-13, 12-6 MVC, RPI No. 52
MSU: 31-18, 11-6 MVC, RPI No. 67
The Bluejays and Bears are the top two teams in the Missouri Valley and both are trying their best to gussy up their résumés to get into at-large consideration. Both obviously have their work cut out for them, especially the Jays, who saw their RPI plummet from No. 42 last week. MoState helped its cause with a big win over Oklahoma State on Tuesday, improving their mark to 6-1 versus Big 12 teams. Watch for a key matchup between CU catcher Scott Thornburg (who is hitting .448 in his last 10 games) and reliever Dan Kickham (saved all three games versus Bradley last weekend), who are the reigning MoValley player and pitcher of the week.

10. Wherever the SEC West leaders are playing
No. 2 South Carolina at Alabama
LSU at Mississippi State
Auburn at Tennessee
No. 18 Arkansas at Ole Miss
The SEC West is quite the wild west, dontcha think? Arkansas, Mississippi State, Alabama and Auburn are all tied atop the division at 13-14 in conference play going into this final weekend. The recipe is pretty simple as all four teams must avoid getting swept at all costs. If they do that, they should be fine for making the SEC tournament in Hoover. Ole Miss is one game back and LSU is just two games back, both still have a shot at the division title too, although the Tigers could sweep State and still not make the field of eight at the Hoover Met. That would make the NCAA bid a very dicey proposition.
