What happened: Cox connected in the top of the second inning on a 92.5 mph four-seam fastball. The drive left his bat at 99.5 mph with a 31-degree launch angle.

Why it matters: The 25-year-old outfielder was recalled nine days earlier. He returned from a left oblique strain less than three weeks ago.

What to watch: The final score will determine whether the early damage proves decisive.
