Soriano hit three home runs on five pitches in the game at Turner Field, including two on the first two pitches he saw. The Cubs won, 9-1.
"I'm always very aggressive, that's why I lead off," Soriano said after the game. "I felt very good, especially when I hit a homer on the first pitch. So why should I have to wait for another pitch if he's going to throw a strike?"
Soriano was batting .463 (19-for-44) in 10 June games heading into the Cubs' Monday night contest against the Astros, and had six home runs, one double, two triples and 10 RBIs. He's also scored 11 runs in that stretch.
