24 matches are on Tuesday's card at US Open, and we have a pick for every one of them. The headline act: Rafael Jodar against Thanasi Kokkinakis in the first round. Our calls: Jodar over Kokkinakis, Gea over Cerundolo, Tiafoe over Damm, Musetti over Fery, Andreeva over Tjen, Valentova over Potapova, and 18 more.
The boldest call on the card: Monfils over Vallejo — the market disagrees with us there.
