C Manny Pina — Pina is a decent second catcher who won’t kill your batting average. I might even consider him as a first catcher in NL only leagues.
1B Eric Thames — Thames started last year looking like Babe Ruth (11 home runs in April) before settling down to hit 31 HR on the season. Thames struggles against LHP (I expect that he will lose at bats in a platoon), but he still should get about 420 at bats hitting against RHP. If that happens, another season of 20+ HR is a distinct possibility.
2B Jonathan Villar — Villar took a big step back in 2017 after his amazing year in 2016. I expect his plate discipline to return as I think he fell too much in love with trying to hit home runs instead of just getting on base. Look for Villar’s SB totals to go over 40 this year, which should place him in the top five in the major leagues.
