Holloway shutout Minnesota (0-3) for the final four innings of Sunday's 4-3 win in front of 2,139 rain-soaked fans in Baum Stadium.
It completed a three-game sweep.
"We played pretty solid especially with a wet infield and just a whole soggy setting," said Arkansas coach Dave Van Horn. "We're going to have to play in this stuff so it's probably good that we got this (weather)."
With no outs and runners at second and third base in the sixth, Holloway (3-0) entered and promptly got the Gophers' top hitter, Andy Hunter, to hit a line drive to third baseman Clay Goodwin for an unassisted double play. He then struck out Kevin Carlson to escape the jam with the score locked at 3-all.
"Both Friday and (Sunday), he was able to locate three pitches in the strike zone," said Minnesota coach John Anderson. "He moves the ball in and out and has great command out there. Plus, he seems like a very competitive young man which I really liked.
"He'll do some good things for them."
The senior left-hander from Booneville picked up his second win of the series by allowing only one hit Sunday. Holloway, who locates an 82-mph fastball, has pitched in five of 10 games and has not allowed a run on five hits in 12 innings.
Last year, it was Sawatski, also a senior left-hander, who often pitched twice during a weekend series. Sawatski was more of a power pitcher -- his fastball was in the low-90s -- than Holloway and was basically a utility pitcher because he was used as a starter, a long reliever or a closer when needed.
"The only difference is they have a little different style," Van Horn said. "Jay would come right at you and Trey is more of a finesse guy that is going to work it in and out and change (speeds) a little bit."
With a deeper pitching staff this season, Holloway likely won't have to start much which he doesn't mind since he said he prefers to pitch out of the bullpen. He said filling Sawatski's shoes won't be an easy task, but added he learned plenty while watching his teammate's approach to the key role last season.
"It was be huge to me to be able to fill that role to help our team out," Holloway said. "I've always watched how good pitchers handle themselves in different situations and Jay is a great guy to follow around because he is such a great pitcher that I really look up to a lot."
Clint Arnold led off the third inning with a double to right and scored on a single up the middle by Casey Rowlett, who extended his team-best hitting streak to 10 games. Rowlett scored on a double down the left-field line by Danny Hamblin to give the Razorbacks (9-1) a 2-0 lead.
Minnesota responded with a two-run single by Jake Elder in the top of the fourth, but the Hogs regained a 3-2 lead when Arnold's sacrifice fly drove in a Scott Hode, who reached on a leadoff double to begin the bottom of the inning.
After Elder drove in another run in the sixth to tie the score, Arkansas went ahead 4-3 on John Marquardt's two-out single that scored Hode, who reached on an fielder's choice and moved to second on a throwing error.
"That was a big hit," Van Horn said. "He hangs a breaking pitch and Marquardt just slapped it into center field. That was a great piece of hitting right there."
Arkansas returns to action at 2:35 p.m. Friday when it hosts the first of a three-game series against Illinois-Chicago.
