OMAHA, Neb.>> Wehiwa Aloy drove in Arkansas’ first three runs with a homer and triple, Zach Root bounced back from a rocky start to pitch five strong innings, and the Razorbacks eliminated the Bruins from the College World Series with a 7-3 victory Tuesday night.

Arkansas (50-14) will play SEC rival LSU on Wednesday night and would have to beat the Tigers twice in two days to advance to the best-of-three CWS finals. LSU won two of three against the Razorbacks in the regular season and beat them 4-1 in a CWS opener last Saturday.

UCLA (48-18) went 2-2 in its first appearance in Omaha since it won the 2013 national title. The Bruins played Arkansas six hours after they lost 9-5 to LSU in the completion of a game suspended by rain Monday night.

Aloy, the Southeastern Conference player of the year, hit his team-best 21st home run in the first inning for a 2-0 lead, and his second triple of the season made it 3-0 in the fifth.

The Razorbacks added four runs late to put the game away.

Root (9-6) lasted just 1 1/3 innings in Saturday’s loss to LSU, the left-hander’s shortest start of the season.

He limited the Bruins to three hits, walked two and struck out five in five innings.

Reliever Aiden Jiminez allowed one hit over three scoreless innings and had the Razorbacks poised to shut out a second straight opponent a day after Gage Wood threw the third no-hitter in CWS history, and first in 65 years, against Murray State.

UCLA capitalized on uncharacteristic blunders to break through against Will McEntire in the ninth. Mulivai Levu tripled leading off and scored when third baseman Brent Ireland couldn’t come up with a grounder.

McEntire’s wild throw to first on a comebacker and a wild pitch brought in two more runs.

The Bruins loaded the bases in the first, but Root got out unscathed when, with two outs, Dean West was caught trying to steal home.

Ryder Helfrick’s sweeping tag touched the headfirst-sliding West’s arm just before West’s fingers reached the plate.

UCLA challenged the call, which was upheld on video review.

UCLA’s leadoff man reached base three of the first five innings. Root worked around a single, walk and two wild pitches to get out of the fifth and then turned things over to Jimenez to start the sixth.

UCLA started Cody Delvecchio (1-4), who was academically ineligible until last week and hadn’t pitched since March 28.

He gave the Bruins a solid four innings and was pulled with two runners on in the fifth.

Ian May relieved and induced a double play before Aloy drove a ball to center that rolled to the wall for his triple.

Louisville walks off Oregon St 7-6>> Eddie King Jr. drove in the winning run with a sacrifice fly in the bottom of the ninth inning that gave Louisville a 7-6 victory over Oregon State on Tuesday and knocked the Beavers out of the College World Series.

The Cardinals (42-23) avenged a 4-3 walk-off loss to Oregon State last Friday and advanced to the Bracket 2 final. They must beat Coastal Carolina on Wednesday and again Thursday to reach the best-of-three CWS finals.

Just like Oregon State (48-16-1) on Friday, Louisville squandered a late lead only to come back and win.

“It’s the value of being the home team,” Cardinals coach Dan McDonnell said. “Sometimes people act like it’s not that big a deal. It’s amazing when you get the last three outs and you get to walk somebody off. So, very fortunate that we were in that situation today.”

Kellan Oakes faced the top of the Louisville lineup to start the bottom of the ninth.

Alex Alicea walked and Lucas Moore was awarded first base on catcher’s interference when his bat nicked Wilson Weber’s mitt as he fouled off a pitch.

The Cardinals loaded the bases when Matt Klein put down a bunt that Oakes (5-1) booted, the Beavers’ third error of the day and eighth in three CWS games.

That brought on freshman Zach Edwards to face Jake Munroe, who got caught looking at strike three.

“I struck out on a call I didn’t like,” Munroe said. “I was upset about it. Did a little 360, saw Eddie, and I said, ‘Oh, yeah, we’re good.’ That’s kind of the special thing about this lineup.”

King fouled off a pitch and took two balls before he sent a fly to center. Alicea tagged up from third, and Canon Reeder had no chance to make a throw home.

King was mobbed behind first base, with teammates squirting their water bottles at him and fans chanting “Edd-ie! Edd-ie!”

“Just hearing chants like that in a moment like that, it warms my heart,” King said. “And I’m so glad that it could be for Louisville.”Cardinals pitchers repeatedly worked out of trouble until they couldn’t in the top of the ninth.

“Right there at the end, we probably shocked the heck out of everybody,” Beavers coach Mitch Canham said. “They bring guys in, we’re finding ways to get on base — hit by pitch, base hit, what have you.”

Aiva Arquette homered to left-center on Wyatt Danilowicz’s first pitch, and Gavin Turley, Weber and AJ Singer reached to load the bases with no outs.
