Altuve (thumb) will move his rehab assignment to Double-A Corpus Christi on Tuesday, Michael Connor of SportsTalk 790 Houston reports.
Altuve has just two hits in his 13 at-bats in his rehab assignment thus far, but his movement to Double-A has everything to do with proximity and weather. The 33-year-old infielder will likely need a few more games before he's ready, and he could return from the 10-day injured list to make his season debut for the Astros as soon as this weekend's series with the Athletics.
