You bet it does.
Recent Example 1: Alex Gordon comes back from the DL with high hopes and great expectations. He attempts to "one hand" a routine pop up in the late innings of close game. The game is just after the All-Star break and could possibly start a decent trajectory for another 4th place finish. What happens when Train Smoke drops the pop up? The Royals fall apart and lose the game, and every person who was ever taught to catch a pop up with two hands, including those who play the game for free, shakes his head in disgust.
Recent Example 2: Alberto Callaspo aka Das Boot drops a pop up in shallow right-center field because, apparently, the "sun got in his eyes." The game was close at the time, and zaniness thereafter ensues. The whole thing had the whiff of Pony League about it and was not a pretty sight. John Buck said it all when he failed to complete the following sentence:
“Good teams, when that does happen, the shrug it off and get that next out,” catcher John Buck said. “But I’d be lying if I said there wasn’t (a letdown). We got the job done, against a good hitter, Ian Kinsler, got the pitch we wanted, got him out front, popped him up on the curveball and…”
If only ellipses could talk...what a story they could tell...
Recent Example 3 in support of the notion that one person's bad performance can affect the performance of others? Right here, at the 2009 Sasquatch Music Festival. Life is a precious gift my friends. You have suffered enough lately. You owe it to yourself, as a Royals fan, to watch the whole thing.
If the Royals were a group of modern-day Hippies at 2009 Sasquatch Music Festival, they would like something just like that.
