Lucas Giolito KO’d in second as Tigers defeat White Sox

Right-hander Lucas Giolito’s encouraging run that had him soaring with confidence came to an abrupt halt in the White Sox’ 8-3 loss Tuesday to the Tigers at Guaranteed Rate Field.

Giolito, who was 3-0 with a 2.84 ERA and 27 strikeouts in his last four starts, had more of the same mojo going during a perfect first inning that featured strikeouts of Jim Adduci and Nicholas Castellanos. But Victor Martinez opened the second with an 11-pitch at-bat that he capped with a single, and the Tigers added three more hits — including two doubles — in a five-run inning.

When Giolito walked Jeimer Candelario with one out, manager Rick Renteria had seen enough and went to left-hander Hector Santiago. Giolito was charged with five runs (four earned) and four hits in 1 1/3 innings, tying a career low.

Giolito said he let the game speed up on him in the second.

‘‘I felt really good going into the game; I thought my stuff was really good,’’ he said. ‘‘Just one of those cases where I let it get too quick for me there.”

Giolito (10-10, 5.85 ERA) is 3-6 with a 7.91 ERA in 14 home starts.

‘‘I just washed it off in the shower,’’ he said. ‘‘Move on to the next one.”

The Sox scored three runs in the fourth against left-hander Francisco Liriano on RBI singles by Yoan Moncada and Adam Engel and a sacrifice fly by Ryan Cordell, who made his first major-league start in right field.

Reliever Jeanmar Gomez struck out five in 1 2/3 innings.

Another young arm to see

The Sox purchased the contract of right-hander Jose Ruiz from Class AA Birmingham, increasing their active roster to 30. To make room for Ruiz on the 40-man roster, the Sox outrighted first baseman Matt Skole to Class AAA Charlotte.

‘‘He’s a young man that has a little flair,’’ manager Rick Renteria said of Ruiz, a converted catcher. ‘‘He’s a pretty excitable guy out there.’’

Ruiz follows right-handers Ian Hamilton and Ryan Burr and left-hander Caleb Frare from Charlotte as recent bullpen arms getting their first looks in the majors.

Jimenez, Cease cited

Charlotte outfielder Eloy Jimenez and Birmingham right-hander Dylan Cease were named the Sox’ minor-league player and pitcher of the month for August.

Jimenez, 21, batted .336/.376/.509/ with four home runs and 16 RBI in 28 games in August and September. Cease, 22, went 3-0 with a 0.94 ERA and 71 strikeouts in 47‰ innings in his last nine starts.

Kopech night

Right-hander Michael Kopech is the Sox’ scheduled starter for the series finale Wednesday. Rain abbreviated his first two home starts, and it’s in the forecast again.

‘‘It is supposed to rain,’’ Renteria said. ‘‘Let’s pray for a little dispensation and it kind of goes around us.’’

Ouch!

A fan in the first row between the visitors’ dugout and right field was struck in the face with a foul ball off the bat of Candelario. The fan, who tried to catch the line drive, was bloodied but walked up to the main concourse under his own power before being taken to Rush University Medical Center.
