The Royals have found their left-handed bat, acquiring 26-year old outfielder Andrew Benintendi from the Boston Red Sox in a three-team trade with the Mets that will send outfielder Khalil Lee to New York, and outfielder Franchy Cordero and two players to be named later from the Royals to Boston.
In a vacuum, you can see why the Royals made this trade. Khalil Lee was a player I was personally very high on (full disclosure - I supported him in the Adopt a Minor Leaguer program and found him very gracious in our online interactions).
