WATCH: Lynn Williams scores 49 seconds into USWNT debut

The NWSL MVP scored quickly after coming on as a halftime substitute in the U.S. national team's 4-0 win over Switzerland.

It's been a good month for Lynn Williams.

The 23-year-old forward scored 49 seconds into her U.S. national team debut Wednesday, netting the opener quickly after entering as a halftime substitute in a 4-0 friendly win over Switzerland in Sandy, Utah.

Williams claimed the NWSL MVP award earlier this month after an 11-goal campaign with the Western New York Flash, then scored a last-gasp extra-time equalizer as her side won the NWSL Championship over the Washington Spirit on penalties.

Tobin Heath, Christen Press and Samantha Mewis also scored at Rio Tinto Stadium for an experimental U.S. side, which saw Andi Sullivan, Casey Short, Abby Dahlkemper and Ashley Hatch join Williams in earning their first caps.

The U.S. faces Switzerland again Sunday at U.S. Bank Stadium in Minneapolis.
