Here's what to watch for throughout the day (all times in ET):
Felix, Sale duel in Chicago: SEA@CWS, 8:10 p.m.
Hernandez and Sale will match up as starters for the second time in their careers as the White Sox and Mariners open a three-game series. This duo last met head-to-head Aug. 21, 2015, in a game the White Sox dominated 11-4.
Both Sale and Hernandez enter today's opener coming off impressive outings. Sale beat the A's with eight scoreless innings, earning his first win since July 2. The Chicago ace was 0-4 with 4.43 ERA in his previous six starts.
"It was kind of getting over the hump for me," Sale said. "My last few times out, I haven't been as good as I've wanted to be or as good as I've needed to be."
Hernandez, meanwhile, allowed just two runs in eight frames in a win over the Brewers. Hernandez is 4-0 with a 3.80 ERA in seven appearances since coming off the disabled list.
Stat that matters: Hernandez deployed his changeup 37.6 percent of the time (41-of-109) in his last start. Thirty-seven of his 57 strikeouts this year have come via changeups.

Wright returns to action: KC@BOS, 7:10 p.m.
Wright will come off the DL to start for the Red Sox against the Royals at Fenway Park. Wright, who has been sidelined with shoulder inflammation, was 13-5 with a 3.01 ERA prior to landing on the DL.
For the Royals, Ian Kennedy gets the start coming off his best outing of the year -- eight scoreless innings in a win against the Twins on Saturday. The right-hander hasn't allowed more than one run in a start since July 25. He owns a 0.79 ERA in that span (34 innings).
Stat that matters: The Red Sox are seeking improved production from Xander Bogaerts, Travis Shaw and Jackie Bradley Jr. The trio is batting a combined .177 (41-for-232) with 65 strikeouts this month.

First-place teams clash in Texas: CLE@TEX, 8:05 p.m.
Two first-place AL clubs will clash in Arlington as the Rangers and Indians continue their four-game set at Globe Life Park. Cy Young candidate Kluber is slated to start for the Tribe. Kluber is unbeaten (5-0) with a 1.78 ERA in his last eight outings.
"He looks like the tank's full," Indians manager Terry Francona said last week, "which is really good for us."
The Rangers will counter with left-hander Martin Pérez, who is facing Cleveland for the first time since 2013. Perez is coming off a loss to the Rays in which he surrendered six runs in six innings.
Stat that matters: Perez has been notably better at home (7-1 record, 2.36 ERA) than on the road (1-8, 6.23) this season.

Verlander, Tigers host Angels: LAA@DET, 7:10 p.m.
The Tigers will continue their playoff push by sending Verlander to the mound in the opener against the Angels at Comerica Park. Verlander has notched eight consecutive quality starts. He limited the Red Sox to one run on three hits in six innings his last time out.
"It's a broken record. He keeps going out there and giving us a chance to win," Tigers manager Brad Ausmus said.
Ricky Nolasco gets the ball for the Angels. He's 0-3 with a 5.70 ERA in four starts since joining Los Angeles via trade from the Twins on Aug. 1.
Stat that matters: Verlander is 5-7 with a 3.77 ERA in 15 career starts against the Angels.
