Arkansas' late-inning comeback attempt fell short on Sunday, and San Diego downed the Razorbacks 7-6 to wrap up play in the Tony Gwynn Legacy tournament.
The Razorbacks (5-2) finish the four-game road swing 2-2 with wins over Arizona and San Diego State and losses to Cal Poly and San Diego.
Barrett Loseke got his first start of the season for Arkansas and surrendered a pair of earned runs on four hits in 2 2/3 innings. Evan Lee spelled Loseke in the third inning and was handed his first loss of the season after the Toreros tagged the sophomore with two runs on two hits.
San Diego turned a one-run deficit into a 7-3 lead with five runs in a fifth inning that saw the Razorbacks commit their sixth and seventh errors of the road trip.
Freshman catcher Casey Opitz recorded his first collegiate hit and RBI in the loss, and came around to score on Eric Cole's RBI single in the seventh inning to bring Arkansas within 7-4. In the eighth, Heston Kjerstad and Carson Shaddy singled, and Grant Koch - pinch hitting for Opitz - hit a flare into shallow center to make it a one-run game.
Reliever Jacob Kostyshock worked around a one-out single in the home eighth, giving Arkansas one last chance in the ninth, but San Diego's Justin Friedman retired the top of the Razorbacks lineup in order to seal the win.
Arkansas returns to Baum Stadium for five games in five days beginning Wednesday against Dayton. The University of Southern California then comes in for a three-game weekend set.
