Who will be the Blue Jays designated hitter this season?

Teoscar Hernandez
Boasting one of the hottest bats over the past two seasons, Teoscar Hernandez is one player that the Blue Jays need to have in the lineup on a regular basis. Earning consecutive Silver Slugger awards in 2020 and 2021, Hernandez took a couple of seasons to find a groove and over the past two years, posted a .295/.345/.538 slash line with 48 home runs, 150 RBI, and a .882 OPS through 193 games. He could have been a contender to lead the league in RBI last year if he didn’t miss some games due to being placed on the COVID-IL and finished five RBI behind Salvador Perez (121).
The Blue Jays used 20 different players last year as the designated hitter. Who will be the club’s primary DH in 2022?
I imagine that Hernandez and Grichuk will most likely rotate when it comes to rest days in right field but I wouldn’t have him hit primarily as the DH considering he has been steadily improving defensively over the past two seasons (-3 and -2 bDRS respectively). Grichuk is no slouch in the outfield either but it seems like the club will have Hernandez primarily play in the outfield (at least for the time being).
