If the Jays can sign a free agent stud outfielder in the off-season, say J.D. Martinez, they could field the following line-up in 2018.
LF- Teoscar Hernandez, CF - Kevin Pillar, RF- J.D. Martinez
3B -Josh Donaldson, SS- Troy Tulowitzki, (Ryan Goins when Tulo gets hurt) 2B- Devon Travis, (Ryan Goins when Travis gets hurt) 1B Justin Smoak ,DH Kendrys Morales
C Russ Martin (Raffi Lopez backup)
SP Marcus Stroman, J.A Happ, Marco Estrada, Aaron Sanchez, Joe Biagini (or one of the bullpen guys)
BP -Roberto Osuna, Ryan Tepera, Luis Santos, Dominic Leone,Aaron Loup, Matt Dermody, Carlos Ramirez
This roster is plenty good enough to at least get a wild card, or potentially challenge for A.L. east crown.
