In his no-hitter against the Chicago White Sox on May 3, Francisco Liriano got a little bit of help from one of the umpires, as they called a White Sox runner out on a play where replay clearly showed that first baseman Justin Morneau missed a tag.
If he manages to hold on to his no-hitter today against the Texas Rangers, he may have to write a thank you card to the official scorer.
In the top of the seventh inning with one out, Rangers' shortstop Elvis Andrus hit a ground ball to third baseman Luke Hughes. Here's what the play looked like:

Now, that might have been a play that Hughes could have made, but he might have had a tough time getting somebody with Andrus' speed. Andrus wound up on second base on the play, but was stranded there by Liriano. I'm not sure if I would have called that an error, but that's what the official scorer went with.
The Twins have given Liriano significantly more padding in their half of the seventh, as they've put up five runs so far to extend their lead to 6-0, and they're still hitting as the Rangers are making their second pitching change of the inning. Hopefully Liriano is finding a way to stay warm.
