He's not serious, he's just butthurt that people are correctly calling out Vlad for coming into camp without having any regard for his conditioning during quarantine (perhaps a bit harsh), forcing the team's hand to move him away from 3B way before they wanted to and then also looking like garbage at the plate when that's supposed to be his calling card. Vlad will be fine, but it's totally understandable that people aren't pleased with him.
