Haven't had a first hand report of him since late May. At that time it was estimated he was closer to 240 than the listed 220 on his 6'2" frame. In terms of performance, he had a bad June (.211) after a hot May (.337). So far for July he is hitting .244 and has hit his first two homers of the season. For a 19 year old in the South Atlantic League, he is not doing too badly.
Overall his stats are:
.257 BA, 22 doubles, 2 hr, 30 RBI's, he strikes out about one every 4.5 at bats. He has had 15 passed balls behind the plate.
I am sure he is on the Astros' weight watcher list.
