There were two games of cricket on the pitches at Hales Meadow. The Cherwell League website says there are 14 days until the start of the season. So these games were probably friendlies or practice matches.
After last years short season, the games are being played under the influence of Covid-19 with risk assessments and using ECB guidance, currently at Step 2 of the Government Roadmap out of Lockdown from 12 April 2021 with progression to Step 3 (no earlier than 17 May 2021).
People should arrive in kits as changing rooms are closed; groups of six apply to people off the field; nobody with symptoms should attend; NHS Test and Trace is carried out etc. I am not sure spectators are allowed but I was just passing.
