What happened: Ryan McMahon hit a grand slam to right field in the bottom of the third inning. His 11th home run of the season scored Luis García Jr., Jazz Chisholm Jr. and José Caballero.

Why it matters: The bases-clearing shot broke the game open early to establish a seven-run advantage. Creating a significant margin in the third inning firmly shifted the game's momentum.

What to watch: The remainder of the game will test whether the early offensive outburst can be maintained.
