What happened: St. Louis CITY SC signed forward Palmer Ault to a first-team MLS contract, promoting him from the club's CITY2 reserve side. The Noblesville, Indiana native previously played at Indiana before turning pro.

Why it matters: The signing comes as MLS's summer transfer window allows midseason registrations, letting new additions make their club debuts. It adds depth to St. Louis CITY SC's attack heading into the second half of the season.

What to watch: Ault could debut for the first team once formally registered under the summer transfer window.
