Lawrie was brough up with a very short rehab stint, so I think its fair to assume he wasn't exactly rounded into game form before being called up.
In the 14 April games he played in, he was horrendous offensively,
So far in 11 games in may, he seems to be coming back to form a bit: 8.5% walk rate, 21% k-rate, and an 18% LD rate ... his .129 babip for the month is clearly unsustainably low
The Groundballs are still too high, but he's trending in the right direction
