SAN DIEGO -- All season long, prospects from the Padres' top-ranked farm system have arrived in San Diego. The biggest name yet arrives Tuesday night.
Luis Urias, San Diego's presumed second baseman of the future, has been promoted from Triple-A El Paso before Tuesday's game against the Mariners.
Urias, 21, is ranked No. 22 on MLB Pipeline's Top 100 prospects list and No. 4 in the Padres' system. He's hitting .296/.398/.447 this season with eight home runs in 120 games this season for El Paso.
The club placed left-hander Clayton Richard (left knee inflammation) on 10-day disabled list.
