Rangers and Pirates rained out

Rain, Rain, Rain! This game was delayed because of rain at the start – I tuned in an hour later, and they were just getting started, so I listened until the second inning when it got delayed by rain again!
McLemore is starting off with a bunch of walks in Spring training again, which is good as it was an important part of the fast start the Rangers got last year.
And then the rain came again. :) The game was postponed for good in the second inning. This time I saw on CNN Headline News that it was postponed for good. A thought occurred today. Do pre-season rainouts have to be made up?
