Starter Randall Fant, rained out in his scheduled start Sunday, got the first two innings, then turned it over to the bullpen. Seven more hurlers trotted to the mound before Colby Suggs got the final out for his eighth save.
The Razorbacks (30-15) took advantage of six walks -- two with the bases loaded in a three-run second -- to put down the Bears on five hits.
Missouri State (27-13) took a 1-0 lead in the first when leftfielder Joe Serrano lost a ball in the sun for a double and Brian Anderson made a throwing error.
"It didn't start very well," said Van Horn, the UA coach. "But our pitchers did a tremendous job. We did a good job working the walks in the second and did some things with a hit and run, a slug bunt. We hit the ball hard four or five times that were outs. You take away the two throwing errors (both by Anderson) and we played pretty well."
Van Horn was asked if he ever remembered using so many pitchers in a game. He thought so, perhaps as many as nine. It went per the plan Tuesday night.
"I thought it went great," Van Horn said. "We matched up (right on right, left on left) a few times, but sometimes we left a pitcher in to get the next one.
"We had a lot of pitchers wanting to get out there. We had some who hadn't pitched much."
The Hogs had a rain out Tuesday against Oklahoma, then lost the final game of the Georgia series to rain on Sunday.
Van Horn had planned to get Suggs work no matter how the game turned out.
"He was going to be on the mound for a bullpen and we were going to bring him in if we needed him," Van Horn said. "So he was going to get his work."
It became a close situation when Jalen Beeks allowed a solo homer in the ninth.
Brandon Moore, who put down a mild MSU rally in the sixth, said Suggs continues to build momentum.
"The key is his breaking ball," Moore said of Suggs. "When that's a strike, he's tough with that fast ball 97. It's exciting to see him work. He's one of our studs. He's one of our leaders.
"I didn't worry about him (when Suggs was battling back from a rib injury) because he's menatlly tough. I hope this continues and I think it will."
The Hogs fought and scratched for seven hits, three by Dominic Ficociello. Brett McAfee had a key two-out, RBI single. Jake Wise and Jacob Mahan both drew bases loaded walks. Joe Serrano and Tyler Spoon added sacrifice flies.
Ficociello pointed to the pitching. After Fant, the Hogs went with Trey Killian, Michael Gunn, Chris Oliver, Moore, Trent Daniel, Beeks and Suggs.
"That's the engine tht keeps this train running," Ficociello said.
But Van Horn said it's good to see Ficociello coming alive at the plate. It was his second three-hit game of the season.
"Confidence is everything in this game," Van Horn said.
Ficociello said he felt good after a solid batting practice before the game.
"My confidence is always there," he said. "I think I'm going to get a hit every time I come to the plate. But I made a few small changes in batting practice and stayed under control.
"I've taken good batting practice before, but I didn't stay calm when I got to the game."
The Hogs travel to Kentucky for a three-game series beginning Friday. The Wildcats are just 9-12 in SEC games. They've won only two of their last 10 games.
"They have a veteran team and they are a lot better than their SEC record," Van Horn said. "They just won a series on the road."
The Wildcats could throw three lefthanded starters. The Hogs got some practice Tuesday night. The Bears went with two lefty hurlers to start the game.
"Kentucky beat us two of three here last year," Van Horn said. "They got pretty excited, too. They celebrated on our field."
