Arizona center fielder A.J. Pollock hit three homers, Nick Ahmed added a homer, and Zack Greinke had his first 10-strikeout game of the season as the Diamondbacks held off the Los Angeles Dodgers 8-5 at Chase Field on Monday. Earlier in the day, the Dodgers learned shortstop Corey Seager will undergo season-ending Tommy John surgery on Friday. Pollock hit bases-empty homers in the second and fifth innings to help Arizona grab a 5-0 lead.
