Opening Day rosters were announced around the league on Thursday, and the season officially began for four teams that played later that night — including the Giants, who lost in a blowout. The other 26 clubs are waiting until Friday to take the field, but at least we know who will be suited up and available.

The Oakland A’s will only face nine different opponents this summer in their abbreviated 60-game schedule. They’ll spend two-thirds of the time playing the other four AL West clubs, and then 20 more total against the five NL West teams. Their division rivals are always frequent matchups, but this year it will be exaggerated even further.

With so much of the season riding on these four particular rivals, let’s take a look at how their rosters shaped up. You can also click here to see the A’s 30-man squad, or scroll down to the bottom of this post.

Here are the rosters. Note the injured lists below each one.

Houston Astros

Of note: Houston is missing one starter (Urquidy) and one key hitter (Alvarez) for undisclosed reasons, which so far around the league has usually been shorthand for coronavirus-related complications; reliever Joe Smith might still opt out of the season but for now and is just on the Restricted List while he decides.

Cool detail: Former A’s prospect Brandon Bailey, traded to Houston years ago for Ramon Laureano, has made the MLB roster and is in line to debut in the bigs any day now.

Cool detail: Former A’s pitcher Chavez is still plugging along strong, with his 37th birthday coming next month.

Seattle Mariners

Of note: Another six-man rotation, and also 17 total pitchers on the staff, even without Hirano as he works back from coronavirus (he’s rejoined the team already); on the hitter side, note that some infielders are obviously helping in the outfield (not a Ryan Sweeney situation).

Cool detail: Former A’s starter Graveman is back in the majors!
