The White Sox found some work Wednesday night for three seldom-used players.
But based on their 10-7 loss to the Angels, it might be a while before those players see action again in those roles.
Timo Perez, playing first base for the first time since 1999 in Japan, committed an error that led to two runs during a four-run fourth.
Left-handed reliever Kevin Walker, making only his fourth appearance since being recalled from Triple-A Charlotte on May 9, allowed four runs in the seventh that enabled the Angels to take the lead for good.
And Luis Vizcaino's struggles continued, as he surrendered a two-run single to Bengie Molina that allowed the Angels to extend their lead to 8-5.
Even closer Dustin Hermanson proved vulnerable. Hermanson saw his streak of 21 consecutive scoreless innings to start the season come to an end as the Angels added two runs in the ninth inning.
Hermanson was used in a non-save situation because he hadn't pitched since May 25, and the Sox are off Thursday.
The shortcomings became more magnified in the ninth, when the Sox pushed across a run off closer Francisco Rodriguez and missed a chance to win when Juan Uribe tomahawked a shoulder-high pitch that sailed foul down the left-field line by a few feet.
After getting into trouble walking three batters, Rodriguez punctuated his game-ending strikeout of Uribe by pounding his chest.
"That's OK. If I hit the homer, I'd be happy too," Uribe winked.
That the Sox nearly salvaged what turned out to be a tedious loss provided little solace as their lead in the American League Central dropped to four games over Minnesota.
The day off will allow the Sox to regroup and get extra rest. First baseman Paul Konerko didn't play for the first time this season, and manager Ozzie Guillen thought about using Konerko only as a pinch-hitter for Uribe.
With Frank Thomas limited to pinch-hitting in the ninth because of a strained hip flexor and Ross Gload on a rehab assignment at Charlotte, Perez was Guillen's best option.
In the seventh, Guillen employed Walker because Damaso Marte and Neal Cotts had been used often recently. Walker was optioned to Charlotte after Wednesday's game, presumably to make room for Orlando Hernandez, who is scheduled to come off the disabled list and start Friday against Cleveland.
The Sox went 14-11 during a stretch of 25 consecutive games outside the AL Central.
For the second time in as many nights, Angels reliever Brendan Donnelly was miffed that he was called twice for a ball for licking his fingers on the mound. He accused Guillen of snitching.
"It's not like I'm on the mound doing it," Donnelly told writers covering the Angels. "I'm not doctoring the ball. It's just a habit. Eating bacon cheeseburgers is a habit, too, and I'm not going to stop doing that. Obviously, this is something I have to stop doing.
"I commend Ozzie Guillen for trying to do anything possible to win a game. I do think it's pretty tired. If I was managing the other clubunless you're blatantly trying to doctor the ballI wouldn't interfere with the players.
"Either he's trying to get in my head or he's trying to get balls called. Whatever he's doing, just go out and win like they've been winning, by pitching and hitting and playing defense."
Said Guillen: "A rule is a rule, and the umpires were aware and they were watching what he was doing."
