Altuve is one of the last guys I want to see up in that situation currently. He's one of the worse with runners on this year.
The way they have been playing, every game is 'winnable' in the 5th inning. They have 8 relievers for a reason. I suspect if Devenski was out there for 2-3 innings and they ended up losing anyway, you'd be hollering tomorrow if they are winning 4-3 in the 6th and need a reliever to come in.
Altuve seems to be pressing, trying to find the same swagger he had last year. He's lost some of the plate discipline that made him an MVP candidate last year.
