NASHVILLE, Tenn. -- Nothing went right for Arkansas' baseball team this past weekend, from the bad weather and lengthy rain delays to the inability by the Razorbacks to drive in runs.

Arkansas coach Dave Van Horn had hoped to use a three-game series at No. 9 Vanderbilt to get his team back on track after its recent slump. But things didn't go according to plan.

Rain washed out one game entirely, and the Diamond Hogs left disappointed after letting an unconventional doubleheader slip away Sunday afternoon with a pair of losses -- 6-5 and 6-2 -- at Hawkins Field.

"Yeah, we would have liked to have played three (games), but we should have won the two that we played, that's the way I look at it," Van Horn said. "We had every opportunity to bust open both of those games and never did, and that's what sends you home early."

Sunday proved to be a short, but frustrating day for the Razorbacks.

Vanderbilt third baseman Brian Harris hit a walk-off double with two outs in the bottom of the 12th inning to lift the Commodores to a 6-5 win and put an end to a game that had started 21 hours earlier.

Arkansas and Vanderbilt began the first game at 3:09 p.m. Saturday, but play was suspended when neither team was able to pull out the victory by midnight. The game included a nearly five-hour rain delay.

But the Commodores finally earned the victory at 12:18 p.m. Sunday when Arkansas' Casey Coon couldn't hold on to Harris' deep shot after jumping up against the left field wall to catch the ball.

"I don't know," Van Horn said. "It was a hard day."

Things were perhaps even more frustrating for Arkansas in Sunday's second game, which started 30 minutes after the first one ended.

The Razorbacks loaded the bases in three separate innings, but came away empty-handed each time. In total, they left 13 runners on-base to allow Vanderbilt to cruise to a 6-2 victory in the shortened, seven-inning game.

As a result, Vanderbilt won its first series over Arkansas in school history, dating back to 1994.

"It's very frustrating to see me myself go down and other guys go down when we've got guys in scoring position with less than two outs," Arkansas right fielder Sean Jones said.

The Razorbacks opened the second game with a single, a sacrifice bunt and a pair of Commodores' miscues to load the bases with no outs. But Arkansas failed to take advantage of the opportunity.

Andy Wilkins hit a shallow flyball for the first out, and the rally ended when Brett Eibner and Jacob House both struck out looking.

The Diamond Hogs had a chance at redemption when they again loaded the bases with two outs in the top of the third. But to Van Horn's dismay, they came up empty.

"That was the most difficult part of the last two days, is leaving all those runners on-base with a chance to really bust the game open last night and probably win it," Van Horn said. "And then again today, in the first inning bases loaded, no outs and we don't score, send all the momentum over to (Vanderbilt's) dugout."

Arkansas right-hander Kendall Korbal (0-4) gave up three hits and four runs in 1 2/3 innings to earn the loss. Meanwhile, sophomore Stephen Richards (1-2) was credited with the loss in the first game, surrendering two hits and one run in 1 2/3 innings.

Unlike the previous two days, Sunday wasn't mired by rain, though the sky was overcast. In total, Arkansas and Vanderbilt faced around 7 1/2 hours worth of rain delays during the weekend.

It made things difficult for both teams.

"You're just trying to get in some type of flow, but you can't," Vanderbilt coach Tim Corbin said. "There was no rhythm to the weekend whatsoever.

"In six years, I've never had a weekend like this ever before as far as weather is concerned."

More Injury Woes

The last thing Arkansas coach Dave Van Horn needed was for another player to get injured, but he received more bad news Sunday afternoon.

Starting catcher Ryan Cisterna suffered what's believed to be a dislocated shoulder when the junior was involved in a collision at home plate early in a 6-2 loss to No. 9 Vanderbilt.

Cisterna stayed on the ground for several moments and held his arm after colliding with Vanderbilt's Dominic de la Osa in the bottom of the second inning.

"Cisterna got hurt, that was disappointing because you're not supposed to run over guys at the plate," Van Horn said. "(The umpires) didn't make a call; they told me (de la Osa) slid. Are you kidding me? How is he going to slide and maybe dislocate a guy's shoulder?"

Van Horn said he'll know more about Cisterna's status today.

Welcome Back, Jones

Arkansas right fielder Sean Jones showed in his first significant action of the season that he has recovered from his broken left hand.

Jones led off the first game with a double to left field, and he added a one-run single in the fourth inning of the 6-5 loss. He went 2-for-6 with one RBI.

The senior returned to lead off the second game with a single, going 3-for-4 in the 6-2 loss. He finished 5-for-10 with for the weekend, a promising start after missing most of the season because of the broken hand.

"I wouldn't say I'm in too much of rhythm. I'm just out there pretty much trying to get my foot down, be on time," Jones said. "I'm just pretty much swinging hard because hopefully good things will come."

Murphree To The Bench

At one time, Arkansas first baseman Aaron Murphree was on an offensive roll. But Van Horn decided to bench the senior for the second game of the doubleheader against Vanderbilt after he went 1-for-3 with one RBI in a 6-5 loss.

Murphree has struggled lately despite leading the Razorbacks with 13 home runs. He had started all 23 games he has played in this season, but he didn't get a single at-bat in the second game -- a 6-2 loss.
