Yeah if they didn't want to start Barger, then DS playing 2B made more sense with Lukes or Straw in the OF. In the last 3 seasons, IKF has a 65 wRC+ against LHP. The Jays being an analytical team but yet making a decision that is clearly "dude bats righty, so put him in there" is ridiculous. Unless they think the defensive upgrade is worth more than the noodle bat, which they might.
Then again, Ned Yost started Alcidis Escobar and batted him lead off when they won the title, so maybe this is JS trying to appease the Baseball Gods.
