The Razorbacks led 10-3 in the bottom of the fifth when the rains came and suspended the game until Saturday at 2:05 p.m.
That's when action is scheduled to resume with a second 9-inning game possibly being played, but a decision on that will be made after seeing what the weather is like on Saturday.
"We would have liked to have finished it, but we've got a runner on first in the fifth and we'll just go from there on Saturday," Arkansas head coach Dave Van Horn said. "We don't need to look to the second game, just finish the first."
A third game is slated for 1:05 p.m. on Sunday and there would no time problems since Mississippi State has a charter plane and is not flying commercially.
If no games are played on Saturday, then there would be a resumption of Friday night's game and an additional 7-inning game on Sunday.
If there is no more action this weekend, Arkansas would get awarded a win for the Friday night game.
"I think we will get them all in," Van Horn said.
Scott Lyons got the Razorbacks going when he drilled a home run to the deepest part of the ballpark in center field.
That was the only hit in three-run first that included two run-scoring errors by the Bulldogs.
Mississippi State cut it to 3-1 in the second against starter Dallas Kuechel when Jet Butler led off with a double and came around on two groundouts.
It became 3-2 in the third when Connor Powers' sacrifice fly drove home Grant Hogue.
Arkansas then blew it open with a seven-run third inning against surprise starter Devin Jones that included a 2-run homer by Travis Sample and a 3-run blast by Ryan Cisterna.
