The Cubs, who are in the midst of constant roster shuffling, received only 51/3 innings from recently promoted starter Dan Straily. Two of the three Cubs' runs came on home runs from Welington Castillo in the fifth and Justin Ruggiano in the seventh.
At the plate
The Cubs scored once more in the seventh with the bases loaded and no outs after Ruggiano's homer but failed to add more runs. Starlin Castro's hitting streak ended at 14 games.
On the mound
Straily walked three, but hitting David Wright with a pitch started a four-run sixth.
In the field
Rookie center fielder Arismendy Alcantara was charged with an error after Juan Lagares' drive skipped off his glove and led to two unearned runs in the sixth.

Straily: "The middle stretch of innings was more the type of guy I am. Those were the most runs I've given up at any level (seven, five earned), so it's not the way you want your first one to go. There's definitely some positives in there in the middle innings. The big (sixth) inning really hurt me."
