Mahan's two-out single with the bases loaded in the bottom of the ninth inning gave the No. 10 Razorbacks a 4-3 win over New Mexico in the nightcap of a doubleheader Tuesday at Baum Stadium.
Mahan, who entered the game as a pinch-hitter in the seventh inning, completed a tedious rally for the Razorbacks, who trailed by three runs in the second inning. The junior had left the first game of the doubleheader in the third inning with a stomach illness.
Arkansas (24-10) split the doubleheader with the Lobos after falling 3-0 in Game 1. The Hogs play host to No. 2 LSU to begin a three-game series on Friday.
"It's been a long day," said Dave Van Horn, UA coach. "(Joe) Serrano and Mahan were sick. But they gutted it out in the second game. They had been throwing up."
Van Horn said he wasn't sure if Mahan was up for it in the ninth.
"I was looking for him in the dugout and I couldn't find him," Van Horn said. "He'd gone up the tunnel and was stretching. He looked a little better when I saw him then. He hadn't had any color in his face, but the color had come back."
Mahan's hit scored Matt Vinson, who was one of three Arkansas batters to reach base with one out in the ninth. Vinson singled and advanced to third on a Tyler Spoon single. New Mexico intentionally walked Dominic Ficociello to put a double play in order and Brian Anderson struck out on three pitches before Mahan won it with his first career game-winner - a liner to centerfield.
After New Mexico scored two runs to build a 3-0 lead in the top of the second, Arkansas scored its first run in 20 innings on an Eric Fisher fielder's choice RBI to score Anderson in the bottom of the frame.
The Razorbacks pulled within 3-2 on Anderson's solo home run to leadoff the fourth inning and tied the game on Spoon's RBI double to plate Vinson in the bottom of the fifth. Hitting in the first two spots in the lineup, Vinson and Spoon combined for five hits in the second game.
Arkansas' defense, which committed three errors in each of Tuesday's games, helped the Lobos stake the early lead. A Jordan Farris throwing error put Chase Harris at third base following a leadoff walk in the first, and Harris scored on a D.J. Peterson two-out single.
The Lobos (17-16) added two more in the second. Josh Melendez singled and scored on a Jared Holley RBI hit, while Alex Allbritton, who reached on a fielding error by Dominic Ficociello, later scored on a sacrifice fly by Harris.
New Mexico chased Arkansas starting pitcher Colin Poche after the freshman left-hander recorded just one out in the first inning. Chris Oliver earned his second win of the season by pitching three scoreless innings, striking out two.
Brandon Moore (3 2/3 innings) and Michael Gunn (2 innings) also logged time on the mound for the Razorbacks. Gunn, a sophomore, left-hander struck out four batters.
Hobie McClain suffered the loss for New Mexico, pitching the final 2 1/3 innings. Lobos starter Taylor Duree pitched 2 1/3 innings, allowing one run on two hits.
"New Mexico has a very good team," he said. "They've faced a tough schedule and they are doing well in their conference. We faced all of their weekend guys.
"We saw a wide variety of pitching -- slider guys, fast ball guys and a sub marine guy. That's why we went with Mahan at the end, against the submariner.
"Vinson had a great at bat to start off the inning. We knew the matchup we had (with Mahan). When I saw him stretching in the tunnel, he looked better. He was getting ready mentally and said he was feeling better."
Van Horn said another big key was an RBI ground out by Eric Fisher in the second inning. It broke a long scoring drought.
"It was close to a double play, but Fisher beat it out," Van Horn said. "It was like the anvil was lifted off of us. It had become a mental thing. We needed to score."
Vinson said, "Once we got that one, it took the pressure off of us. And then that was a gutsy performance by Mahan. He showed us he's in it for the right reasons. He's in it for the team."
New Mexico 3, Arkansas 0 (game one)
New Mexico scored three runs on three Arkansas errors and the Lobos beat the Razorbacks 3-0 in the first game of a doubleheader Tuesday at Baum Stadium.
The Razorbacks failed to score a run for the second consecutive game, recording just six hits off New Mexico. Arkansas stranded runners in scoring position in the first and second innings, and stranded the bases loaded in the sixth.
New Mexico starting pitcher Drew Bridges threw 5 1/3 innings to improve to 2-1. The right-hander entered the game with a 5.87 earned run average. Josh Walker pitched the final 3 2/3 innings.
The Lobos (17-15) scored twice off Arkansas starter Tyler Wright, who pitched two innings in his first loss of the season. Wright issued two walks and threw a wild pitch to give New Mexico a run in the first inning. Sam Haggerty, who scored the run, reached on an error by first baseman Jacob Mahan.
Haggerty singled to leadoff the third inning and advanced to second base on a throwing error by Arkansas shortstop Brett McAfee, and later scored on a Mitch Garver RBI. A fielding error by Razorbacks third baseman Jordan Farris pushed home New Mexico's final run in the fifth.
Arkansas (23-10) leads the NCAA with a 1.59 team ERA, but has allowed 29 unearned runs this season. The back-to-back shutout losses are the Razorbacks' first since 2005.
