Sucks to lose Leo, but I get it.
He’s added a lot of weight and may not be a plus defender at SS anymore. Not fat, just stockier now at 5'10", 215.
His OBP is promising, but it relies a lot on getting beaned and his walk rate probably takes a dive without much power at the MLB level.
It would be tough to option Lukes, who’s a solid player at the end of his prime, and DFA’ing Straw probably means losing him since he has five years of service time. The Power of Friendship wins.
The team is high on Kasevich and he had a good spring, he might be the better option anyway.
Leo doesn’t have a huge ceiling to me, and it’s possible no team claims him since everyone is making tough roster decisions right now.
If the Jays need infield depth later, they could probably trade for someone similar without giving up much.
