Bolded part is incorrect. He was just above average last year and based on his trend he will likely be average defensively this year. He's been at 2.0 WAR exactly for the past two years, trending down.
A team in contention with injury issues will pursue many other available options before enquiring on Pillar.
I expect Pillar to be a non-tender after this season unless the Jays manage to get a bag of balls for him.
