This is correct. To elaborate, balls lost in the sun, moon, or artificial stars are considered the equivalent of a ball that takes a bad hop. No error. Another possibility is losing the ball coming out of the crowd background.
In general, and contrary to popular misbelieve, you don’t have to touch the ball to get an error. This is stated directly in the rule book (rule 10.12, err comment on 9.12(a)(1) "It is not necessary that the fielder touch the ball to be charged with an error). Of course, there is a whole lot of unwritten rules to score keeping too. As a practical matter, an OF is only going to get an error on an untouched ball if (a) it rolls between his legs, or (b) in the situation where 2 or more fielders all pull up short and look at each other while a pop-up drops between them.
Have an issue with the left fielder also. He should have realized immediately that Duran was lost (the play-by-play guy knew it) and ran over hard to cover him sooner.
Stieb’s best season was leading the league in ERA at 2.48 on a team that won 99 games
and he went 14-13.
Jack Morris won 21 games on the Jays at 37 vs Stieb’s highest of 17 in his entire career, and was completely washed up at 34. (btw, that was the same year/team of Stieb being washed up and Morris winning 21 games)
