The Sounds were handcuffed in the first game and busted loose in the second but still suffered a doubleheader loss against New Orleans on Sunday.
Callix Crabbe's line-drive single to left in the fourth inning was Nashville's only hit in the opener despite the fact that the Sounds struck out only four times against three Zephyrs hurlers in dropping a 3-0 decision.
Steve Hammond (0-4) remained winless since his promotion, allowing two runs on four hits and one walk in four innings while striking out seven. Chris Narveson pitched two scoreless innings, but Tim Dillard gave up two walks and two hits for one run in an inning.
It was just the opposite in the wild nightcap as the Sounds overcame a 9-1 deficit with a four-run fourth and seven-run sixth for a 12-9 lead. However, New Orleans regained the upper hand with a four-run seventh for a 13-12 win and the sweep.
Brendan Katin's two-run double highlighted the fourth-inning uprising, while Laynce Nix's 17th homer, a solo shot, capped the big sixth that featured five singles and two sacrifice flies. Adam Heether clubbed his eighth homer in the third.
Nashville starter Lindsay Gulin, who entered with a 2.89 ERA, got roughed up for nine runs on eight hits in 3.1 innings as his ERA jumped to 3.67. Randy Choate stopped the bleeding with 2.2 innings of scoreless ball, but usually reliable closer Luis Pena (1-1) got tagged for five hits and four runs in two-thirds of an inning.
The Stars sit at 14-11, two games behind Tennessee in the Southern League's North Division as they prepared for Monday night's All-Star game.
Shortstop Alcides Escobar and catcher Angel Salome will be starters, while third baseman Mat Gamel participated in Sunday's All-Star Futures game, as did former right fielder Matt LaPorta, recently shipped to Cleveland in the CC Sabathia trade.
Also making the North squad are outfielder Michael Brantley, first baseman Chris Errecart and pitchers Patrick Ryan and David Welch. Hurlers Joe Bateman and Hammond also were selected but were moved up to Class AAA Nashville.
Huntsville resumes action with a five-game home stand, all against the first-place Smokies, so they could move into first place with a good series. Lefty Brae Wright, who's 6-7 with a 3.47 earned-run average, is scheduled to start for the Stars.
Darren Ford's two-run double capped a four-run fourth and three Manatees pitchers combined for a four-hitter as Brevard County snapped a five-game losing streak with a 5-0 triumph over Sarasota.
Catcher Jonathan Lucroy continued his steady hitting, leading the visitors with two hits in five trips to bump his average to .326. Left fielder Scott Houin went 1 for 1 with a double and two runs scored.
The Power haven't suffered a clinker in some time, but Sunday's 9-3 setback to Charleston was just that as the visitors fell behind 8-0 after two innings.
West Virginia had its eight-game winning streak broken as it dropped to 18-6 and saw its lead shaved to three games over Lakewood as the Power managed only five hits and committed three errors.
Daniel Merklinger (3-6) was tagged with the loss, giving up a walk, four hits and four runs while getting only two outs in the first inning. Reed Dickert then gave up four more on five hits during the next 3.1 innings.
The Brewers got back to the .500 mark at 13-13 with a convincing 8-2 victory against Casper, scoring two runs in four separate innings.
Right fielder Erik Komatsu got back on track with three hits, including a double and triple, to lead a 12-hit attack. He also scored four times. First baseman Brock Kjeldgaard stayed hot, going 3 for 4 with two doubles and four RBIs. Shortstop Michael Marseco added two hits.
Lefty Efrain Nieves improved to 4-1 with seven strong innings in which he allowed only three hits and didn't walk anybody.
The Brewers exploded for six runs in the eighth but it was too late as they already trailed 14-2 at the time en route to a 17-9 defeat to the Athletics.
Greg Miller (0-1), the second of six Brewers hurlers, suffered the loss.
