4. Right-handed hitting outfielder
The Tigers have ton of lefty bats in the outfield—Riley Greene, Akil Baddoo, and Austin Meadows and Kerry Carpenter when healthy. What they seriously lack is a solid right-handed bat in the outfield.
Matt Vierling has had his moments, but he's very inconsistent. He may be better off as a fourth outfielder like he was in Philly. Fortunately, looking at the free agent market, there are three free agent RHH OF that catch the eye.
Teoscar Hernandez is the first one. He's off to a rough start with Seattle this year, but he has a history of being a productive power hitter. If he continues to struggle, it may be worth it to offer him a one-year prove-it deal.
Hunter Renfroe is another option. He's off to a pretty good start for the Angels and also has a history of hitting for power. Randal Grichuk could be a cheaper option. He's off to a scorching start for Colorado, though it's only 60 plate appearances.
There's always the trade market as well. The Tigers desparately need a right-handed power bat in the outfield, and they have options this offseason.
