"This is a very, very good ballclub," Thomas said of the White Sox, now 52-29 and off to the second-best start in franchise history behind the 1919 club (53-28).
All-Star starters and reserves will be announced this week.
"Anybody can go," said Baldwin (11-3). "They want big names on the All-Star game and a lot of people look at this team and there aren't any big names. Frank and Magglio, those guys are pretty big, but we've still got to focus on our No. 1 goal, which is to win.
Ordonez matched his career high for RBIs with a three-run homer in the first inning and a solo drive following Thomas' 23rd home run in the third. Ordonez also hit a sacrifice fly in the seventh.
"Magglio, he's very underrated," Thomas said.
Ordonez does have a good feel for why the White Sox are doing so well.
"We've been playing together in the minor leagues and we come to the big leagues together we're like brothers, we're like family," Ordonez said. "Every time we cross the lines, we pick each other up."
Ordonez now has 19 homers and batted .488 (20-for-41) with five home runs and 17 RBIs on the just-completed 13-game homestand. Tomas batted .391 (18-for-46) with seven home runs and 12 RBIs during the stretch.
The White Sox went 8-5 on the homestand and have won 21 of their last 27 games.
"Guys are getting better by the week," Thomas said. "We've got that total team thing."
Baldwin, second in the AL in wins behind Toronto's David Wells, snapped a two-game losing streak. He is one win shy of his 1999 total when he went 12-13.
Baldwin gave up two runs on five hits and three walks over 7 1-3 innings, striking out five. The right-hander waved his glove as he left to a standing ovation from the crowd of 32,934.
Pete Schourek (2-7) dropped to 0-4 in his last nine starts, giving up five runs on six hits and two walks over five innings.
"It was a bad time to have nothing," Schourek said.
Nomar Garciaparra, the AL's leading hitter, went 0-for-3 and is batting .389 as the Red Sox lost for the seventh time in their last eight games.
"I don't think it's going to take one game," Schourek said of the Red Sox's efforts to get back on track. "We're going to have to play perfect baseball for a series to get our confidence back. This game is all about confidence."
"You've got to keep playing," Boston manager Jimy Williams said. "You've got to keep playing. There's only one thing that'll cure it - it's a victory."
With one out in the Chicago first, Tony Graffanino doubled, Thomas walked and both scored on Ordonez's 18th home run to make it 3-0.
With one out and the bases loaded in the third, Garciaparra hit a sacrifice fly to make it 3-1.
Thomas and Ordonez hit consecutive homers with two outs in the third to make it 5-1, the 10th time this season the White Sox have hit consecutive homers.
