HOUSTON — The Oak­land Ath­let­ics had one mem­ber of their orga­ni­za­tion test pos­i­tive for COVID-19, caus­ing Major League Base­ball to post­pone the team’s game Sun­day against the Hous­ton Astros.

The finale of the A’s three-game series at Minute Maid Park was called off less than four hours before it was sched­uled to start.

The A’s said the team con­duct­ed test­ing and con­tact trac­ing for the entire trav­el­ing par­ty Sun­day morn­ing and would self-iso­late in Hous­ton with rec­om­mend­ed safe­ty pre­cau­tions in place.

The Astros beat the Ath­let­ics 6–3 on Sat­ur­day night for a dou­ble­head­er sweep. They won the first game 4–2. The dou­ble­head­er was sched­uled after the A’s and Astros decid­ed not to play Fri­day night to raise aware­ness of racial inequal­i­ty in the wake of the police shoot­ing of 29-year-old Jacob Blake, a Black man, in Wisconsin.

COVID-19 test­ing has now post­poned 38 games. All 30 major league teams played Sat­ur­day the same day for the first time since July 26.

MLB’s plan to play a pan­dem­ic-short­ened 60-game reg­u­lar sea­son has been inter­rupt­ed by pos­i­tive coro­n­avirus tests, protests over racial injus­tice, a hur­ri­cane and rain — and that’s just in the past week.

The Astros and Angels moved up Thursday’s game to Tues­day ahead of Hur­ri­cane Lau­ra, which made land­fall in Louisiana on Thurs­day morn­ing. Houston’s game on Wednes­day against the Angels was postponed.
