Monday’s spike in the price of gasoline won’t make Vigo County high school fans any fonder of class basketball today, when all three teams head east for sectional openers.

Terre Haute South and Terre Haute North are at the Class 4A Mooresville Sectional, hoping to set up a third meeting between the two teams this year in Friday’s first semifinal game. West Vigo fans will go almost as far, and on less accommodating roads, to Spencer, where the Vikings play the second game of the Class 3A Owen Valley Sectional.

Northview will play Friday, also at Mooresville.

Rematches are the order of the day for two of the Vigo County entrants, with North’s Patriots hoping to repeat the outcome of a 70-40 win in early January over the host Pioneers — that game was in Terre Haute, however — and West Vigo trying to reverse a 61-41 loss at Sullivan earlier this month.

South’s Braves would probably like to enjoy a rematch of their own on Friday — if not against the Patriots then against the Pioneers, who handed South one of its more frustrating losses in a frustrating season back in December. But the Braves have to do a lot of good work tonight to make any of that possible.

“We’ve got our hands full with Martinsville,” cautioned Coach Mike Saylor of his team’s opener tonight, “and that’s 100 percent of our concentration.

“[Martinsville’s] kids are so tough, they are extremely well coached, and they have skill and quickness,” Saylor added of a team that could certainly be considered a sectional dark horse. “But we’re looking forward to the opportunity to compete [and try to defend South’s 2005 championship], that’s for sure.”

North, 4-0 so far this season against potential sectional opponents, has to be considered the favorite, and Coach Jim Jones doesn’t seem to mind that situation.

“Right now we’re at the top of our game,” Jones said after the Patriots thumped a good Indianapolis Cathedral team and played top-ranked Lawrence North close for most of the game four days ago. “You hope you can gain a little bit more as you go through the tournament.

“But if we can go in [to Mooresville] and play three good games, I’ll be happy.”

Northview, sitting in the short bracket with a team that’s won nine of its last 10 games, ranks as another potential spoiler, of course.

“We’ve played some pretty good basketball down the stretch,” Coach Mitch Lancaster of the Knights, who play Plainfield on Friday, agreed. “We feel we’re playing our best, and we’re looking forward to the tournament.

“North is the favorite on paper, but the rest of the teams are all pretty close.”

The tournament at Owen Valley would appear to be a Western Indiana Conference showdown between 15th-ranked Edgewood, the WIC champion that’s beaten every other team in the field, and the host Patriots, who finished 18-4 and were Pizza Hut Wabash Valley Classic runners-up.

Potential spoilers here include Brown County, which plays Edgewood in tonight’s opener after losing just 49-46 to the Mustangs earlier, and Sullivan — and the Vikings would like to play spoiler for the Golden Arrows.

“Two games out of [the last] three we’ve played with heart and desire,” said Coach Tommy Thornton of the Vikings, looking back at victories over Clay City on Feb. 17 and North Knox a week ago. “We played with the effort offensively and defensively that I know [the Vikings] can.

“I’m glad we got some time to prepare, to get [the Vikings] hungry again,” Thornton added.

In Class 2A sectionals around the Wabash Valley, a spectacular semifinal game looms at South Putnam, while Linton’s Miners hope to reverse a late-season trend at Paoli.

Second-ranked Tri-West and 11th-ranked Cloverdale could meet on Friday at South Putnam, but South Vermillion could upset those plans on Wednesday by upsetting the Bruins. Another potential spoiler could be Cascade, 10-10 overall but 6-1 against sectional foes; the Cadets await the winner of tonight’s opener between North Putnam and the host Eagles.

Despite losing their last three regular-season games, the Miners still have the best overall record at Paoli — but meet the host Rams in the second game today. Eastern Greene is in the bye bracket with the second-best record in the field.

Class A sectionals in the Valley look completely up for grabs, with six Wabash River Conference teams meeting at North Vermillion and the SWIAC/Tri-River teams battling at White River Valley.

Five straight wins have given Riverton Parke the best record at the North Vermillion Sectional, but the Panthers have to avenge a regular-season loss to Attica today. Rockville had a 53-49 win during the season over Covington, its foe tonight, while the bye teams — Turkey Run and the host Falcons — split during the season.

At WRV, perennial favorite Bloomfield hopes to repeat a 46-39 regular-season win over a hot North Central team tonight, with the winner facing Terre Haute’s Holy Cross — coming off its first-ever win over a public school, a 46-44 decision Friday at New Harmony — in the semifinals. Shakamak and Clay City would appear to be heavy favorites in Wednesday’s games, except that Shakamak’s earlier win over Union was a one-pointer and Clay City’s two wins over the host Wolverines were by a total of just 12 points.

All championship games are 7:30 p.m. Saturday.
