The boxscore from the Cubs’ 4-3 loss to the Diamondbacks does not show any errors made by the Cubs.
And yet, I am going to assert to you that poor defensive play was the major cause of this defeat.
Let’s start at the beginning.
Drew Smyly put the D-Backs down scoreless in the first two innings and then the Cubs got to work offensively. Jason Heyward led off the third with a double and advanced to third on a single by Jonathan Villar.
Both runners scored when the ball got past D-Backs right fielder Pavin Smith.
