If you have your hands on a Learjet this weekend, here are the places you need to get to, pronto.

1. No. 4 South Carolina at No. 1 Florida
By the numbers:
South Carolina: 16-4, 2-1 SEC, RPI No. 14
Florida: 20-2, 3-0 SEC, RPI No. 1
I don't think this one needs a whole lot of hype. It pretty much sells itself, to say the least. Last year, Florida went into Carolina Stadium in late May and won two of three from the Gamecocks, which all but sewed up their national seed in the NCAA tournament, while also being a catalyst for Carolina missing out on a top-eight placement. Things look bleak for the Gamecocks again, right? I mean, they're facing a team that went to LSU and won three straight. The Gamecocks had been hitting a wispy .286 until Tuesday night's 24-run barrage versus Charleston and will need to be at their best to even have a chance in this series. Or so one would think.
Key matchup: Michael Roth versus the Gators batting order on Friday. This will be the key showdown with the biggest ramifications this weekend. The Friday ace of Carolina comes in 4-1 with a 1.34 ERA, 38 strikeouts and nine walks. His quality can't be questioned. But he's coming off his first loss of the season last Friday against Georgia and will need to regroup against a versatile and dangerous Gators bunch that comes in hitting .340.

2. No. 16 Arizona at No. 8 Arizona State
Arizona: 16-5, RPI No. 82
Arizona State: 16-5, RPI No. 9
These rivals come into the Pac-10 opening weekend from very different paths. ASU is battle tested and has some impressive wins on its ledger, including a series win at Auburn and a pair of midweek wins over then-No. 2 Oklahoma. The Wildcats are still a mystery team. Sure, they lead the Pac-10 with a .347 batting average and sport an impressive 2.82 team ERA, but they've piled up those stats against the 205th-ranked schedule, according to Boyd Nation's ISR ratings. This is either a coming out party for Arizona to announce that it's back on the national stage or a "meet the new boss, same as the old boss" declaration by the Devils.
Key matchup: The runners versus the catchers. ASU and UA have the most stolen bases in the Pac-10 with 41 and 37, respectively. In fact, the top five base stealers in the conference come from these two mercurial squads, including ASU's Johnny Ruettiger (14-of-19) and UA's Bryce Ortega (12-of-13). But the big key is timing, because neither team gives up freebies often to its opponents, as they have stolen just 11 bases off the Wildcats, and just two off the Devils.

3. No. 6 Texas at Oklahoma State
Texas: 16-5, 3-0 Big 12, RPI No. 21
OSU: 16-5, 1-2 Big 12, RPI No. 64
So far it appears as if the Pokes have been following the Augie game plan to their good start, pitching at a 2.37 combined ERA pace and playing .973 defense, both of which are good for second best in the Big 12. And for what it's worth, the Cowboys hit better than the Longhorns, too, at a .314 combined batting average compared to UT's weakling-like .257. So what's not to like about the Cowboys' chances here? Well, check out the key matchup first.
Key matchup: Mr. Jungmann, Mr. Stafford, Mr. Knebel versus the Pokes' bats. Taylor, Sam and Corey, two of the weekend starters and their outstanding frosh closer, are going to be unlike anything the Cowboys have seen so far this season. That's what happens when a team plays a schedule ranked at No. 210 then gets a cold slap of reality. … Well, that is, unless we're horribly underrating coach Frank Anderson's young squad. Feel free to prove us wrong guys, we'll admit it.

4. No. 2 Vanderbilt at No. 13 Arkansas
Vanderbilt: 20-2, 2-1 SEC, RPI No. 12
Arkansas: 17-4, 1-2 SEC, RPI No. 46
It may be way, way too early to say that a team's season is on the brink. But the Hogs will have three of their next five SEC weekends on the road, and one of the two home weekends will be against LSU. So things could unravel quickly, unless this youthful squad can pull a confidence-building weekend versus Vanderbilt. Do I really need to tell you that Vanderbilt counters with a really dominant pitching staff? Didn't think so.
Key matchup: The Commodores' arms versus the patience of the Hogs' bats. Led by the blistering bee-bees of Sonny Gray, who has 46 Ks already, the Commodores lead the conference by a large margin, with 218 strikeouts as a staff. But yes, they will be plying their wares in the electric environment of Baum Stadium, which is a huge X-factor for the Hogs. Keep in mind, the Razorbacks strike out nearly seven times a game on average and will toss out a young (but talented) order in front of VU. I still like the Commodores here.

5. Wichita State at Oregon
WSU: 15-6, RPI No. 59
UO: 12-7, RPI No. 90
This may not be one of the more marquee faceoffs of the weekend, but I'm looking forward to seeing how this a four-game set turns out. Both teams could use a reaffirming weekend to say the least. Don't put too fine a point on the RPI numbers, as they are still out of whack, but as things settle down and these two teams move up in April and May, this series will be a huge boost for whoever wins it. I think it's a more imperative weekend for the Shockers, since their RPI numbers will be dragged down a bit by the Missouri Valley Conference.
Key matchup: WSU starting pitchers versus Oregon's psyche. The Ducks have almost zero offense to speak of, hitting a Pac-10 worst .234. I mean, their pitching can go toe-to-toe with the Shockers' talented staff, no doubt, since they're holding opponents to a paltry .229 average. But guys such as J.J. Altobelli (.213), Tyler Kuresa (.218), Shawn Peterson (.238) and Danny Pulfer (.286) need to get over their mental gymnastics and find some holes in the defense if the Ducks are going to turn things around before facing Pac-10 pitching staffs.

6. No. LSU at Georgia
It's a Jekyll and Hyde matchup. LSU's bats have gotten hits, but there are innings that their offense seems to struggle with runs. The Bulldogs can play really bad one week (series loss at Stetson) then really good the next (swept the Dodgertown Classic). UGA also played South Carolina close last week, including a Friday night win behind Alex Wood's pitching gem. We'll have to see which Bulldogs team shows up here at home.

7. Tulane at Southern Mississippi
I love this key early C-USA matchup. Both teams can play some quality baseball, with both defenses sweeping above .974 and both staffs sporting a team ERA below 3.00. The big difference comes when these two teams straddle the dish, as the Eagles feature weapons such as B.A. Vollmuth (.333-5-19), Marc Bourgeois (.351) and Tyler Koelling (.397). The Greenies have only one player that goes better than .280. But how about reliever Nick Pepitone, who already has more saves this season (9) than he posted all last year (8)?

8. No. 15 Georgia Tech at Miami Any other season, this series might get top billing, but the Canes had a sluggish start and fell out of the rankings. But since then, they've started to heat up, sweeping their first two ACC weekends and matching Tech's 6-0 start in conference play atop the Coastal Division. Tech's Mark Pope has been a saint on the hill for the Jackets, racing out to an ACC-best 5-0, 0.23 mark with a 32:4 strikeout:walk ratio. Tech leads the conference in hitting (.336) and pitching (1.96), but this will be its first tough road weekend.

9. Central Florida at Rice
The Owls begin their defense of the Conference USA championship and put together a pretty solid weekend sweep versus Louisiana Tech last weekend, holding a good-hitting Bulldogs offense to just six runs and committing just two errors in those games. The Knights have a couple of demons to bury here, including last season's last-place finish in the conference and early losses to Dartmouth, Mount St. Mary's and South Florida this year. Keep in mind that the Knights hit .321 compared to the Owls' struggles at .274.

10. Texas State at Lamar
The Friday matchup of State's Carson Smith against LU's Blake Ford is as interesting as it gets. Smith has been dinged the last few starts, including giving up 12 hits to Sam Houston and seven hits in 7.1 innings against Houston in the last two weeks. Meanwhile, Ford has been on lockdown mode, holding his opponents to six hits in his first 16 innings of Southland play. But beware of the rest of the Cardinals' staff and its knack for issuing a lot of free passes, with 101 walks already in 23 games.
