OMAHA — Next year, every team that qualifies for the College World Series will demand to stay at the Hilton Omaha, one block south of TD Ameritrade Park.

Besides being the nicest hotel near the ballpark, this year, the Hilton housed both teams that advanced to the championship series — the two-time defending champion South Carolina and Arizona. That inspired the South Carolina left-hander Michael Roth, the team’s ace and resident goofball, to recast the championship series as the Hilton Hotel Battle Royale.

“We’ve been seeing these guys all week,” Roth said Saturday. “Probably the worst part is, at some point in this next week somebody is going to be celebrating, and the other team has to hear.

“So, I mean, that’s probably the only downside. And there’s no free breakfast.”

Arizona Coach Andy Lopez, who is trying to join Augie Garrido of Cal State-Fullerton and Texas as the only to coaches to win national championships with multiple universities — Lopez’s first came at Pepperdine in 1992 — suggested his own clever name for the series, a reference to his longtime friend and colleague Ray Tanner, the South Carolina coach.

“We’re excited to be invited to the Ray Tanner Invitational,” Lopez said. Tanner laughed.

Game 1 in the best-of-three championship series is Sunday at 8 p.m. Eastern. Games 2 and 3 (if necessary) are set for Monday and Tuesday nights.

South Carolina is seeking to be the second university to win at least three consecutive national crowns; Southern Cal took five straight from 1970 to 1974. Tanner cited Arizona’s .330 team batting average to try and claim the underdog role for the Gamecocks, but that’s not his only worry. Arizona starting pitchers Kurt Heyer, Konner Wade and James Farris combined for 15 complete games, matching the output of the entire Southeastern Conference.

Back at the hotel, the players discovered one more thing to deal with. The Olympic swimming trials begin Monday at the CenturyLink Center, which is connected to the hotel by a skyway.

“I think we’re getting outnumbered by the swimmers,” said Arizona right fielder Robert Refsnyder, a fifth-round pick of the Yankees. “The whole lobby smells like chlorine.”
