Yelich's 2022 expected batting stats per Statcast are by far the best on the team:

The only thing giving me pause a little bit is that expected stats across the entire league are currently under performing actual stats by quite a bit (BA by -0.020; SLG by -0.068, wOBA by -0.025). I assume that's due to a combination of possible factors including weather, humidors in all parks, as well as MLB presumably only using one type of baseball this year (the deadened one) instead of the two different baseballs they used last season.
Still, Yelich has significantly under performed his expected stats even if you take into consideration the league wide gap, especially his Expected Slugging.
Even if you look at Yelich's actual line right now, .242 BA / .455 SLG / .380 wOBA, that would still be a massive upgrade over his performance last year. If the expected stats are unto something and he ends up with a >.500 SLG coupled with a high OBP then he'll provide enough to be the impact bat they need to him to be.
