Former A’s infielder Mateo tests positive

A week after he was traded from the A’s to the Padres, infielder Jorge Mateo tested positive for the coronavirus.

San Diego manager Jayce Tingler said Wednesday that Mateo tested positive in his intake test before he reported to the team and has not been to the ballpark. Mateo is experiencing symptoms and is selfisolating.

Oakland dealt Mateo to San Diego on June 30 for a player to be named.

Welcome back: Several teams welcomed back players who might have been exposed to the coronavirus.

In Boston, third baseman Rafael Devers practiced at Fenway Park for the first time since the Red Sox opened summer camp. Devers and an unspecified number of other players were working out at nearby Boston College and have since tested negative three times.

Texas first baseman Ronald Guzman was on the field after missing the first five days of workouts. Although he was at the facility, he wasn’t cleared for workouts while still going through intake testing.

The only Texas players still not cleared to participate are right fielder Joey Gallo and lefthander Brett Martin, both of whom tested positive.

In Cleveland, outfielder Franmil Reyes was cleared by the team’s medical staff to return to the field after being isolated for attending a party over the July 4 weekend.

Also, outfielder Delino DeShields Jr., who tested positive for the coronavirus, is traveling to Cleveland after he had one negative test. He will be tested again when he arrives.
