Yordano Ventura will start the game for Kansas City. Ventura has had an impressive rookie campaign, posting a 3.38 ERA with a 3.67 FIP over 152 innings. His strikeout rate has slowly declined throughout the year, but it still sits at a respectable 20.3%.
Shane Greene will take the mound for New York. Greene posted fairly average numbers in Triple-A, but has looked like a competent major league starter after 10 starts, posting a 3.88 ERA with a 4.08 FIP. Eno Sarris of Fangraphs points out that Greene's sinker/slider combo leaves him vulnerable to lefties, which isn't great if you pitch half your games in Yankee Stadium.
This should be the last time that the Royals play against Derek Jeter. The only thing I care about, however, is that the Royals are in first and the Yankees are not.
