Altuve (finger) is back in the lineup Sunday against the Mariners, Ryan Divish of the Seattle Times reports.
The Astros held Altuve out of the lineup Saturday while he dealt with a sore left index finger, but it was likely just precautionary, as the second baseman came on to pinch hit later in the contest. He'll be inserted into his usual spot atop the order Sunday and is a safe activation in all weekly leagues.
