Weird Play in Oakland tonight

[LeeBallanfant]

Runner on 1B and one out in Bottom 1. Grounder to 2B, runner on 1st stops and 2B chases him back towards 1B where the fielder tags runner with glove but ball in other hand. Fielder then throws to 1B to try to get batter.

Bob Davidson, 1B umpire, apparently rules initial runner safe, but ignores play on batter at 1B. The initial runner than heads for dugout thinking he had been tagged out. Final ruling a DP with Marquez (2B Umpire) making the out call on batter.

Announcers say initial runner out for abandoning the baseline and heading for dugout.

If anyone can download a clip it would be interesting
