Rays fan so I am bitter anyway
I have no doubt it was an infield fly and was called correctly and by the book. The left line blue made the call when all the boxes were ticked, and because of the depth those boxes were ticked slightly later than is normal. No problem there for me.
I am also surprised that so many people here are getting this wrong or making the call from personal feelings. Almost every day we get discussions about umpires making calls because they feel the "rule" is bush league or not important (See our rattling bats and batting box discussions for reference).
As an umpire you read the rule book, read the league rules (If different and they oh so often are), you call the games according to the rules. And you then read the rules again, and again and again.
Often players read the rules, or have the rules read to them if they are beer league players
, and then vaguely remember them in a format that simply supports their current need (He safe if we are on offence and he was waaaaaaay out blue if on defence).
So maybe there should be a sticky explaining the infield fly, oh wait, there is.
