Alejandro De Aza hit a two-run homer in his first at-bat of the season and the Chicago White Sox beat the Detroit Tigers 2-1 on Wednesday.
De Aza, who was called up earlier in the day to fill a roster spot opened by a trade, connected against Max Scherzer (11-6) in the second, hitting an 0-2 pitch over the wall in right for his first major league homer.
Austin Jackson hit a leadoff homer in the seventh but that was it for Detroit against John Danks (4-8) and two relievers.
Danks (4-8), who left after Jackson's fifth homer, matched a career high with 10 strikeouts while improving to 4-0 with a sparkling 0.98 ERA in his last six starts. The left-hander allowed six hits and walked three.
Chris Sale replaced Danks and worked 2 2-3 perfect innings before Sergio Santos got the last out for his 21st save in 24 chances.
Scherzer (11-6) struck out eight in six innings, yielding six hits and four walks.
The White Sox closed within 3½ games of Detroit in the AL Central, a threshold Chicago has reached, but not surpassed, since mid-April. The Tigers fell to 23-13 against AL Central opponents, still the best intradivision record in the league.
Alexei Ramirez had a one-out walk ahead of De Aza's homer in his 195th at-bat in the majors. The speedy center fielder had previous stints with the White Sox and Florida Marlins.
De Aza was called up from Triple-A Charlotte after the White Sox traded starting pitcher Edwin Jackson and utilityman Mark Teahen to the Toronto Blue Jays for reliever Jason Frasor and pitching prospect Zach Stewart.
White Sox general manager Kenny Williams said De Aza will get regular playing time in place of Alex Rios, who is hitting .208. Williams said "Rios is going to have to take a back seat now."
Rios hasn't homered since June 19.
Danks used all those strikeouts to work out of several jams.
The Tigers loaded the bases with one out in the third, but Danks struck out Ryan Raburn and got Magglio Ordonez to bounce into a force play.
Danks walked Miguel Cabrera and Victor Martinez with none out in the fourth, then struck out Jhonny Peralta, Carlos Guillen and Wilson Betemit in order to end the inning, all swinging.
Danks struck out Ordonez with two runners on in the fifth. Ordonez entered the game hitting .577 (15 for 26) career against Danks.
The White Sox just missed adding to their lead in the seventh.
Adam Dunn drew a one-out walk to load the bases for Carlos Quentin, who missed a grand slam by a few feet, his drive hooking outside the foul pole in left. He drove the next pitch down the right-field line, but it curled into the seats.
Quentin finally flied out to shallow left and Juan Pierre was cut down at the plate by left fielder Raburn.
