A's place 6 players on COVID-19 list

The A's made their longawaited home debut Monday without closer Lou Trivino as well as veteran infielders Chad Pinder and Jed Lowrie after the team placed six players on the COVID-19 injured list prior to their matchup with the Baltimore Orioles.

Top prospect Nick Allen and Christian Lopes, both infielders, and reliever Sam Selman were called up as roster substitutions.

Also on the COVID-19 list are catcher Austin Allen and relievers AJ Puk and Kirby Snead. That trio already was on the restricted list and didn't travel with the team to Toronto over the weekend for the final leg of a season-opening threecity trip, presumably because they are not vaccinated.

Outfielder Stephen Piscotty went on the COVID-19 injured list on Friday.

Catcher Christian Bethancourt, infielder Drew Jackson and pitchers Ryan Castellani and Zach Logue were called up before the Toronto series as substitute players.

The COVID IL does not have a minimum length of stay.

Despite the roster uncertainty and a challenging opening road trip, the A's entered their home opener against the Orioles with a 5-5 record.

Allen, 23, was the A's third-round pick in the 2017 draft and helped Team USA win the silver medal at the Olympics last summer. He's known for his superior defense, especially at shortstop, but was more than holding his own at the plate with Triple-A Las Vegas. Allen was hitting .319 with a home run and had scored nine runs over 12 games so far in 2022. He also had drawn six walks, an appealing attribute to a team that has drawn the seventh-fewest walks in the majors so far this season.

Lopes, 29, was batting .289 with three doubles for the Aviators. He joined the A's as a minor league free agent this winter after stints with four other organizations.

Selman, 31, pitched the Giants for parts of the past three seasons before being traded to the Angels in a deadline deal last season.

The A's claimed the lefthander off waivers from the Angles in March.
