Kershaw himself said he thought his pitches were "effectively wild," with a lot of the Cardinals batters swinging high out of the zone. I don't expect him to maintain that level of success against more patient lineups.
Kershaw will still give up his fair share of walks as his efficiency is still a work in progress, as expected. For what it's worth, he tossed 108 pitches yesterday and so, if he has his moments where his control is more spot-on, he might go deeper into games. The schedule doesn't look that threatening on paper after all. Regardless, he's still more than decent than an average #4-5 starter.

I've been happy with the reacquisition of Kershaw for my team, league is relatively deep, although I don't expect more dominant starts like the former, if he provides a high 3 ERA with 8+ k/9 I'll enjoy his presence greatly as a FA pickup.
