The 11 fourth-inning runs are tied for the most runs in a single inning in College World Series history.
"We didn't try to have the big at-bat, didn't try to hit it out," said Florida infielder Josh Tobias, the Phillies' 10th-round pick in the 2015 Draft. "We tried to grind out at-bats, hit the ball up the middle and take the walks when we got them, and just keep adding on to each at-bat and string them together."
Virginia and Florida play in the winner's bracket at 8 p.m. ET on Monday, while Arkansas and Miami square off in an elimination game at 3 p.m.
The fourth inning began with a leadoff walk issued by Miami left-hander Andrew Suarez (second round, Giants) and a dual error play by shortstop Brandon Lopez. It snowballed from there, as the Gators sent 16 men to the plate (nine hits, two walks).
"Everything that could go wrong went wrong," Miami coach Jim Morris said.
Meanwhile, Virginia shortstop Daniel Pinero and the Cavaliers swiped their way to an afternoon victory, using five stolen bases -- three by Pinero -- to surprise Arkansas. Virginia entered with only 62 stolen-base attempts all season.
"Our plan was to be aggressive from the start if the situation presented itself," Virginia coach Brian O'Connor said.
Pinero knocked a one-out single in the eighth to chase Arkansas starter Trey Killian, and promptly stole second and third with reliever Zach Jackson on the mound. O'Connor admitted the steal of third had him a little nervous, considering the heart of the order was up and Pinero did it on his own.
"I saw something I could take advantage of, and I got a huge lead and I just kept creeping," Pinero (36th round, Tigers) said. "It was like: All right, let's go, whatever."

Virginia third baseman Kenny Towns (20th, Angels) plated Pinero with a two-out, go-ahead double.
Arkansas center fielder Andrew Benintendi (No. 7 overall, Red Sox) turned in an all-around solid game in a losing effort, going 1-for-2 with a home run, sacrifice fly and a diving, run-saving catch. Killian (ninth round, Rockies) took the loss, allowing four runs on seven hits and striking out six in 7 1/3 innings.
"I was leaving it up, and they capitalized on my mistakes," Killian said. "Most of the time … especially here in the College World Series, if you make a mistake, other teams will take advantage of it."
