Santana is a high obp 2-3 war player. Maybe he’s on a reasonable contract rather than a surplus value contract, but would certainly be an upgrade on Morales, and would also open up DH should they move Smoak as well.
Definitely agree that it would be pointless for wins and losses, unless the Jays can take a step forward in 2019/20. If they plan a strict rebuild and lower payroll by a s*** ton, then yes it wouldn’t make sense. But value in versus value out, it would be a clear upgrade and add wins.
