I like VMart a little better this year. His contract is up after this one, so this may be the last really good season for Victor Jesus Martinez. You can't get more consistent than him. He has only had less than 14 HRs once in a full season and that was the year he hit .330 and drove in 100 plus while still hitting 12 homers.
But I see Salvador having a very good year this year as well. Low strikeout guy in his first few seasons. I think he's gonna strike out a little more, and his batting average will drop to a more reasonable .280 and he'll club 20. I imagine his 100 singles from last year will drop while his doubles go up to the 30 range.
If it was me, I would keep VMart though.
