"I talked to Altuve before the game ended [Saturday] night and told him he was going to take the day off," Porter said. "He's played every day, played an All-Star second base. We've had a lot of long innings and he's been on his feet a lot. I saw this as an opportunity where an off-day today, off-day tomorrow would give him a chance to get his legs underneath him."
Altuve entered Sunday ranked tied for second in the Majors in hits (43) and tied for eighth in multihit games. His 130 at-bats were third only to Baltimore's Manny Machado (132) and Boston's Jacob Ellsbury (131).
"It's the manager's decision," Altuve said. "He told me yesterday, 'I'm going to give you a day off to take two days in a row and come back strong.' I'm going to be ready anyway in case I have to pinch-run, pinch-hit or whatever. I'll be ready."
Meanwhile, third baseman Matt Dominguez was out of the lineup for only the third time in 31 games. He had started 12 consecutive games prior to Sunday.
"He's played almost every day since he got hit in the elbow [last month] and had to miss a game," Porter said.
