DETROIT (AP) Jarrod Saltalamacchia's drive was so high in the air, it was fair to doubt whether it had the right trajectory to clear the wall in right-center field.
''I saw the outfielders kind of meeting right at that little Bermuda Triangle out there, so I got a little scared,'' Saltalamacchia said. ''When I didn't see them catch it, I was definitely happy.''
Saltalamacchia's two-run homer in the bottom of the eighth inning lifted the Detroit Tigers to a 4-3 victory over the Chicago White Sox on Monday night.
Justin Upton also went deep for the Tigers, who pulled within a game of Baltimore for the American League's second wild card.
Detroit trailed 3-2 after a solo homer in the seventh by Chicago's Tyler Saladino, but Saltalamacchia's towering drive off Nate Jones (5-3) put the Tigers ahead.
It was Saltalamacchia's 12th homer of the season.
''For a backup catcher, he's had some production,'' manager Brad Ausmus said. ''He's contributed to the offense quite a bit.''
Justin Wilson (4-4) got the win in relief, and Francisco Rodriguez pitched a perfect ninth for his 37th save in 40 chances.
Saladino drove in all three Chicago runs. James Shields allowed two runs and six hits in six innings, ending an awful August on a decent note, but the White Sox couldn't hold a one-run lead for him.
''The first couple innings I was a little erratic, but I thought I settled down and was able to pound the strike zone,'' Shields said. ''I've really done that in my last few starts, but tonight I think I had more luck.''
Shields was 0-4 with a 13.95 ERA in five August starts coming into Monday's game, but the Tigers didn't do much against him. Miguel Cabrera hit a sacrifice fly in the third, but Saladino's two-run single put the White Sox ahead the following inning.
Upton tied it in the sixth with a solo home run. Saladino led off the seventh with his eighth homer of the season.
Chicago used three relievers to get through the seventh, and Jones came on in the eighth. He walked Martinez, and Saltalamacchia went deep one out later.
''You just have to tip your hat because Nate has been as consistent as anyone out there,'' Chicago manager Robin Ventura said. ''Salty's gotten us a few times before.''
Detroit starter Matt Boyd allowed two runs and seven hits in four-plus innings.
Rodriguez earned his 423rd save, moving one ahead of Billy Wagner for fifth on the career list. Cabrera's third-inning RBI gave him 1,003 with the Tigers, tying Alan Trammell for 10th in team history.
Chicago's Jose Abreu had a single and a double and has reached base in 25 consecutive games.
Ausmus said before the game rookie RHP Michael Fulmer would likely start Saturday at Kansas City. That would give Fulmer six days' rest between starts as Detroit tries to manage his workload.
White Sox: CF Adam Eaton was in the lineup after leaving Sunday's game because of a bruised forearm. He went 0 for 4 with a walk.
Tigers: RHP Mike Pelfrey (lower back strain) allowed a run and three hits in three innings in a rehab start for Triple-A Toledo at Indianapolis. He struck out two. ... CF Cameron Maybin left in the fifth with a bruised left thumb.
White Sox: RHP Anthony Ranaudo (1-1) starts Tuesday night against the Tigers. He allowed six runs in 5 1/3 innings in his most recent start, Thursday against Seattle.
Tigers: LHP Daniel Norris (2-2) takes the mound. He allowed two runs in 6 1/3 innings Thursday at Minnesota.
