I went to a Frederick (O's High A) vs Winston-Salem (WS High A) game this past Saturday and the ump was horrible. First he calls a W-S guy out on a play much like yours with a swinging bunt down the first base line that the Fred. pitcher fielded and then had to dive for the tag because both the firstbaseman and the secondbaseman broke for the ball, despite the fact that it looked like the pitcher missed, and then on the first play of the top of the next inning, the first baseman for W-S fielded a ball and clearly tagged the Frederick runner, but the runner was called safe. The W-S manager argued and managed to get the call reversed after bringing in the homeplate ump. Later in the game, on what was a tailor made double play ball to short, the SS for Winston-Salem underthrew the ball to 2B, causing the 2nd baseman to misplay it and have it come out of his glove, the runner slid in, clearly safe because the ball was on the ground, but the ump still called him out and would not listen to the Fred manager. This probably cost Fred the game as they were rallying from being down 5-0 and were down 5-3 with runners on 1st and 2nd and 1 out in the inning. That and he blew a couple of pick offs that were the Fred pitcher clearly had the guy.
