Rapid Reaction: Indians 8, White Sox 6

Here’s a quick look at the Cleveland Indians' 8-6 win over the Chicago White Sox in the first game of a doubleheader at Progressive Field on Monday.

How it happened: White Sox starter Philip Humber endured his third consecutive rough outing since throwing a perfect game on April 21. Humber allowed nine hits, eight runs and two walks in 2 1/3 innings on Monday. Over his last three starts, Humber has given up 21 hits, 20 runs, five home runs and 11 walks in 13 1/3 innings. The Indians opened up Monday’s game with five runs in the third inning and took an 8-2 lead. Michael Brantley and Casey Kotchman each had three RBIs for the Indians. Cleveland starter Zach McAllister, who attended Illinois Valley Central High School in Chillicothe, Ill., earned the win. White Sox pitcher Jose Quintana made his major league debut Monday when he replaced Humber in the third inning. He allowed one hit and no runs in 5 2/3 innings. Alexei Ramirez got the Sox closer in the ninth inning with a two-run single to cut it to 8-6.

What it means: The White Sox fell to three games under .500 (13-16) for the first time this season. They’ve gone 3-10 since being four games over .500 on April 23.

Outside the box: The White Sox starting staff appeared headed in a positive direction two weeks ago. That doesn’t appear to be the case any longer. Humber has allowed 20 runs in his last three starts. John Danks has given up 13 runs in his last two outings and has a 6.51 ERA on the season. Chris Sale looked sharp through five starts, but he’s now being moved to the closer role. It’s a move that will likely improve the bullpen, but weaken the starting rotation.

Up next: In the second game of the doubleheader on Monday, Eric Stults (0-0, 0.00) will make his season debut for the White Sox and his first major league start since 2009. He was 1-1 with a 2.20 ERA in five starters in Class AAA this season. Josh Tomlin (1-2, 5.27) will start for the Indians.
