As long as Jeffers is starting 130 games a year which is what he’s or pace for then I’m fine the way they’re doing it right now
Vázquez is better defensively than Jeffers. I think we can all agree that Jeffers should be playing catcher more often but right now with Buxton hurt and Lewis hurt and Wallner in the minors, who else is going to take up that time at DH? If Jeffers is at catcher more often right now, he’s likely playing less games overall so you’re getting the worse defensive catcher, less games with Jeffers and you’re really only replacing Vasquez with Margo, Kiriloff, Martin, or farmer (all brutal options right now)
Until the bench looks better Jeffers and Vázquez should be in the lineup as often as possible as long as Vázquez never DHs
