In a game heard on WHOW, Yainer Diaz hit his first major league home run to back rookie Hunter Brown and help the Houston Astros beat the Chicago White Sox 4-3 on Sunday for their fourth win in five games.

Yordan Alvarez hit a two-run double in the first, advanced on shortstop Tim Anderson’s throwing error and scored on Kyle Tucker’s sacrifice fly as the Astro built an early lead. Diaz, who debuted last September, homered off Lucas Giolito (2-3) in the fourth for a four-run advantage.

Luis Robert Jr. homered for the third consecutive game and Jake Burger also went deep for the White Sox, who have lost four of five and seven of 11.

Burger, recovered from a strained oblique that had sidelined him since May 3, cut the deficit to 4-3 with a two-run homer in the sixth.

Brown (4-1) allowed three runs and seven hits in 5 2/3 innings, walked one and tied his career high with eight strikeouts.

Ryan Pressly pitched a 1-2-3 ninth for his seventh save in seven chances.

Robert drove his 11th homer in the fourth.

Giolito allowed four runs and seven hits in six innings.

White Sox C Carlos Pérez was optioned to Charlotte. C Yasmani Grandal (right hamstring tightness) was available Sunday and could return to the lineup Tuesday, Grifol said. Grandal was scratched Saturday after he left Thursday’s 4-3 loss at Kansas City. 

RHP Liam Hendriks (non-Hodgkin’s lymphoma) struck out one in 1/3 of an inning in a rehab appearance with Charlotte as he nears a return.

Chicago had yet to announce its starter for Tuesday against Cleveland and RHP Shane Bieber (3-1, 2.61).
