LOS ANGELES — Christian Walker, Yainer Diaz and Jose Altuve each homered, Ryan Gusto threw six strong innings, and the Houston Astros beat the Los Angeles Dodgers 5-1 on Sunday to complete their first three-game sweep at Dodger Stadium since May 9-11, 2008.

The Astros concluded a six-game road trip with three wins in a row over NL's top team. It was Houston's first sweep at Dodger Stadium since 2008,

Three of Roberts’ four right-handed hitting reserves — Teoscar Hernández, Kiké Hernández and switch-hitter Tommy Edman — were unavailable because of minor injuries, which could force the Dodgers to make a roster move to bolster their bench depth before Monday night’s series opener at Milwaukee.
