Mets win opener 11-7; is this a good sign?

The Mets won their opening game from the Pittsburgh Pirates 11-7, at PNC Park. One game is no way to predict how a season may go. What, if anything, can we conclude from this game?

 In the first inning, Mets batters jumped on the Bucs' starter, Cy Young Award winner Paul Skenes, for five runs. Skenes was taken off the mound. What could this mean? Were the Mets batters really hot? Or, was Skenes just having a really bad day? I suspect it was more the latter than the former. 

What happened after Skenes' awful outing? In the bottom of the first Mets' starter Freddy Peralta gave up two runs, then one in the third and another in the fifth, when he was retired. The Mets' bullpen gave up one in the sixth and two in the top of the ninth. Over this post Skenes period Mets batters scored one in the fourth, three in the fifth, and two in the sixth. Not bad, but if we discount the five Mets' runs scored off Skenes in the first, the Bucs outscored the Mets 7-6.

So, what can I conclude from this game? Not much. I remain cautionally optimistic.
