Walker Buehler allowed two hits over eight innings, Corey Seager hit a three-run homer and the Los Angeles Dodgers defeated the Arizona Diamondbacks 3-1 on Monday night at Phoenix Buehler (6-1) struck out a season-high 11 batters without a walk. The right-hander was perfect through 4 2/3 innings before Christian Walker caught up to a high 98 mph fastball, driving it above the 413-foot mark in left-center field. Buehler allowed only one more runner -- a two-out single by Ildemaro Vargas in the eighth.
