Right-hander Gavin Floyd had his best outing of the season Sunday, but the White Sox’ bullpen, which had been so reliable, let him down in the seventh inning.
Matt Lindstrom — who had his eight-inning scoreless streak snapped — and Donnie Veal were charged with four runs in the Twins’ 5-3 victory, which gave Minnesota a sweep of the rain-shortened two-game series.
The Sox have lost nine of their last 12 and fell into last place in the American League Central behind the Indians.
‘‘It’s just one of those [games] where every guy has a walk or you give them a little life by putting a guy on,’’ manager Robin Ventura said of the seventh. ‘‘It’s going to happen on occasion.’’
Lindstrom (1-1) walked the first batter he faced, Trevor Plouffe, and gave up two singles. Veal entered with two outs but walked Joe Mauer to load the bases. Jesse Crain gave up a bases-clearing double to Josh Willingham.
Floyd worked through six innings, giving up a run and three hits, striking out six and walking three. He left with a 2-1 lead.
‘‘It’s a bittersweet thing,’’ Floyd said. ‘‘You’re happy you did well and not happy the team lost.’’
‘‘He had a good game, and you take a positive out of that,’’ Ventura said.
Shake it up
Ventura isn’t opposed to shaking up the lineup if the offense sputters.
‘‘You have more flexibility when you have guys on the disabled list,’’ he said. ‘‘I have no problem doing that.’’
He kept struggling Adam Dunn in the lineup against left-hander Scott Diamond, who fanned Dunn twice.
But Dunn homered in the seventh off Josh Roenicke, ending his career-worst stretch of 31 hitless at-bats.
He struck out again in his last at-bat against Glen Perkins.
‘‘For us to turn around and start playing better, [Dunn is] going to have to get some hits and be part of that — part of the answer,’’ Ventura said.
The Sox only had four other hits: Alejandro De Aza doubled and singled, and Tyler Flowers and Paul Konerko singled.
Jeff Keppinger drove in two runs with a ground out and a sacrifice fly.
‘‘Today we were doing at least some small stuff, with Kep knocking them in from third,’’ Ventura said. ‘‘But it’s got to be extended.’’
