BATON ROUGE — Amidst the bedlam of heading to Omaha and an emotional, final farewell to Alex Box Stadium, LSU’s Kramer Robertson almost forgot Job 1 on his to-do list.

But by Monday morning his cell phone had a new screen saver.

“I have not touched my phone yet,” Robertson smiled at the realization during the 2 a.m. postgame press conference following LSU’s late, late 14-4 victory Mississippi State.

“But it will be changed before I go to sleep tonight.”

The old picture, almost exactly a year old and a constant reminder, showed Coastal Carolina players dog-piling at Kramer’s shortstop position after shocking the Tigers to earn their own trip to Omaha last season.

“I hated that picture,” head coach Paul Mainieri said.

“I hate it, too,” Robertson said. “I’m so glad I get to change it and never think about it again.

In its place, he said, would be a picture of the NCAA baseball national championship trophy.

That’s very much in play now that the Tigers won their 16th straight game to earn the school’s 18th trip to the College World Series beginning this weekend.

“Omaha, get ready, because here come the Tigers,” Mainieri said. “We’re going to enjoy ourselves. Hopefully we’ll be there for a while.”

“I’m not sure it’s sunk in yet,” Robertson said.

 It took a while. Three rain delays — including a potential buzz killer with two outs in the ninth and LSU already leading 12-4 — pushed the somewhat anti-climatic postgame dog pile back to just past 1:30 a.m.

“We had to have a rain delay — OK,” said Robertson, who was on the team but not the travel roster when the Tigers last went to Omaha two years ago. “It’s not like I haven’t waited long enough for this moment.

“I’ve waited my entire baseball career … I could wait a little while longer through a couple of rain delays.”

At least a third of the original Alex Box crowd of 11,706 waited with them until the drizzly end.

They saw an emotional moment after the morning skies cleared —just before closer Hunter Newman recorded the final three outs — when Mainieri pulled Robertson and fellow seniors Cole Freeman and Greg Deichmann out of the game for a curtain call.

They hugged and walked off arm-in-arm, to be greeted outside the dugout by starting pitcher Jared Poché.

All four could have left the program for pro ball after last year’s loss to Coastal Carolina, but returned for their senior seasons.

“This is why we came back,” Robertson said. “It’s why we all came back, for nights like this.

“I was just overcome with emotion. Just to think back where we started and now being going to Omaha.”

LSU, which had to rally with four runs in the bottom of the eighth to win the first game Saturday 4-3, also trailed early Sunday but took control with a six-run fifth inning for a 9-4 lead.

Catcher Michael Papierski had the go-ahead RBIs in both games, including a bases-loaded double Sunday that ignited the fifth inning.

Papierski has always had more of a knack for the clutch hit than putting up gaudy numbers.

“Pap just looked so confident up there, you could tell he was going to get it done,” Mainieri said. “He smoked that ball into the rightfield corner.”

A mere 16 games ago, LSU was a 32-17 and wondering if it would even host an NCAA regional.

“At various points along the way some people doubted that we could do it,” Mainieri said. “But we never lost hope, never lost belief. I think what we’re doing now is what we’re supposed to be doing.”

The Tigers have now won five championships in the last three weeks — the SEC West and a share of the overall conference title to go along with the SEC tournament and the NCAA regional and super regional titles.

But there’s one big one to go — the really big one.

“We have as good a chance as anybody,” Mainieri said.

“There’s no question we have a really good ballclub,” he said. “We have a blend of veterans and young players that are playing with extreme confidence. Our pitching is outstanding.

“We just have to out there and take it one game at a time.

“It’ll take our best effort. We’ll have to play as well as we can and we’re going to have to have a little bit of good fortune as well.”
