The A's are an embarrassment at home where they are 7-20 and drawing fewer than 4,000 fans. 

Oakland is 1-5 in its last six games and must deal with an angry Justin Verlander, off his worst start of the season. Verlander gave up six runs on 10 hits in a 6-1 loss to the Mariners this past Friday. Verlander entered that game riding a 19-inning scoreless streak with a major league-best 1.22 ERA. 
Verlander is 14-7 lifetime against the A's with a 2.90 ERA, although he last faced them in 2019. Look for Verlander to bounce back and dominate a weak A's lineup that ranks in the bottom three in the major offensive categories. 

Cole Irvin gets the start for Oakland. He hasn't pitched badly this season, but has an 0-3 career-mark against Houston with a 7.40 ERA in four starts. 
The A's went 10-21 in May. Each of their last 13 losses have been by more than one run.

So I feel confident laying a reasonable number on the run line in order to reduce the heavy juice.
