What happened: Arizona and Atlanta meet with the Diamondbacks holding a 2-0 lead in the series. Atlanta enters at 70-47 on the season, Arizona at 65-52. The two sides awaited first pitch in Wire Report's earlier look at the matchup.

Why it matters: A series sweep or split carries weight for both clubs as the stretch run tightens the standings picture. Atlanta arrives on a one-game losing streak after going 3-2 over its last five, while Arizona is 3-2 over the same stretch with a one-game winning streak.

What to watch: First pitch will set the tone for whether Arizona extends its series lead or Atlanta cuts into it.
