Dominguez is not in the lineup Saturday, the Houston Chronicle's Jose de Jesus Ortiz reports. Gregorio Petit will get a rare start at the hot corner, as Dominguez is given a standard day off. He is one of several Astros (other than Chris Carter and Jose Altuve) who have not lived up to the starting role they've been given this season, and his long-term future with the team is probably still up in the air. His .226/.266/.349 slash line makes him unusable in standard leagues that count batting average or OBP.
