ball stuck in fence

Take the mesh out of it... what if the fielder picked up the ball and on the throw tossed it into dugout.   The batter and runner is awarded 2 bases from the base he last legally occupied at time of throw.  From the OP, it would appear that the batter/runner legally obtained 2nd when the fielder "fumbled" the ball into the mesh, the man in 1st would be at third.  I have 2 runs scoring.  If the runner and batter/runner were both between first and second, then the runner gets third and the batter/runner second.  It all depends where the runners were at the time of the throw that caused the ball to be out of play... in this case the fumble.  It is not when the ball actually crosses the out of play line or gets stuck in the fence.

The umpire's call would appear correct if in his/her opinion it was the throw to first that caused the ball to lodge in the mesh and not the fumble by the fielder.

If the fielder pushed the ball (at rest) into the mesh, it's 2 bases from the time of the push.  FYI, there is no rule awarding 1+1 under any rules code.

That is a very good point, I was out in the area where this happened so I had a very good view, but if umpire thought it went in mesh from throw to first (he was a long way off I can see how that would be hard), then it makes perfect sense. thanks for all input, I guess it really matters where the umpire viewed when the ball went into the mesh and he made that desicion based off that. Thanks for input

You got your answer on the OP, so I will address the 1+1. This is a misnomer that is passed down from generation to generation. Most out of play awards are two bases, with exceptions, but never 1+1, it just looks like it. The two bases is either time of the pitch, time of the throw or time of interference. 

Micahel, that makes sense. 2 bases, just everyone calls it 1 +1. In a sense same thing but your point is way more specific and i appreciate it. thanks

Not really at all the same thing.  Best example is runner being picked off by catcher (or in an appeal attempt after a caught fly) -- if its 1+1 then he gets first (the base he was going to) plus 1 = second.  In truth, he gets third.

As pointed out, two bases and 1+1 are not the same thing.  Another example that I have had is R1, off before the pitch and has rounded second is headed for third when F6 throws the ball out of play. 

Perfect examples of why it is 2 bases and not 1 + 1. you guys are the best. thanks!!
