Johnny Cueto is set to take on his former Kansas City teammates today when the Giants host the Royals at AT&T Park. Just a few short years ago, Cueto was helping Kansas City to a World Series championship after joining the club in a Trade Deadline deal in 2015.
That's just one of several intriguing matchups on tap for today's 15-game schedule, which also features starts by two of the game's hottest pitchers in Edinson Volquez and Ervin Santana. Fans can catch all the action streaming live on MLB.TV.

World Series rematch: KC@SF, 3:45 p.m. ET
Cueto appears to be rounding back into form after holding his opponents to six earned runs across his last three starts heading into this showdown of 2014 World Series contenders. The right-hander is 1-2 with a 3.79 lifetime ERA vs. the Royals, for whom he played 13 games prior to joining the Giants.
Right-hander Jason Hammel will toe the rubber for Kansas City. Hammel pitched seven strong innings against the Astros his last time out, allowing just one run, but received a no-decision when the Royals bats managed just three hits.

Santana takes the hill: SEA@MIN, 8:10 p.m. ET
Santana rebounded from his worst start of the year to toss a Major League-best third shutout in 2017. Santana held the Giants to four hits and a walk while striking out five batters and even contributed with his bat, knocking a bases-loaded double in the fourth inning. He was remarkably efficient, needing just 91 pitches to get through the outing.
"He was locked in and established his fastball," Twins manager Paul Molitor said. "I don't think he hung a slider all night. He either painted it or threw it down and away. His changeup was working. ... He was dominant."
Opposite Santana will be Mariners rookie Sam Gaviglio. The right-hander is 2-1 with a 2.67 ERA since joining the Seattle rotation from Triple-A Tacoma. He matched his career high with six innings against the Blue Jays his last time out.

Harvey at home: CHC@NYM, 7:10 p.m. ET
Citi Field hasn't been kind to Harvey in 2017. He owns a 6.11 ERA in 28 innings at home compared with a 4.23 ERA on the road (38 1/3 innings). The Mets hurler tossed his first scoreless outing his last time out -- five innings in Atlanta on Friday -- and is now looking to improve his efficiency to allow him to pitch deeper into games.
"It's tough and really puts the bullpen on notice a lot," Mets manager Terry Collins said of Harvey's early exits. "I thought [Friday] was a step forward for Matt, and maybe this will kick-start him and get him going."
Chicago will counter with southpaw Mike Montgomery, who receives a second start with Kyle Hendricks on the disabled list. Montgomery went four innings against Colorado last week, allowing two runs on three hits and three walks.
