The terrible weather made me think again about how Citi Field could use a roof, which I’ve suggested before. So I looked into it, and word is it’d be a billion dollars-plus to add one now.

They did it across the street for the U.S. Open, but there’s much more area to cover for a baseball field.

The time to do it was at the time of construction. The Wilpons struggled building consistent winners, but as real estate people, they hit a home run with magnificent Citi Field.

The one negative is they should have included a retractable roof, which was then (at construction time) only around $120 million-$150M extra.
