Where do I go?

[Andy]

Since we are slow and most of us are not calling, I want to post a play that happened to me this last summer and ask for opinions. ASA JO FP. Bear with me as it may take a bit to describe:

4th or 5th inning, R1 on first, no outs, I'm BU in B position. The catcher is very aggressive and has attempted a few pickoffs of runners at first throughout the game, so I am a few steps closer to first than I would normally be. B2 pops up about 7-10 feet behind first base, just inside the foul line. The ball will come down about 8-10 feet directly to my left. F3 is backpedaling toward the fly ball, F9 is charging hard, and F4 is also running toward the ball. I do not move as I do not want to get in F4's way. R1 is staying close to first as she doesn't know if the ball will be caught.

Ball drops in between three fielders in fair ground. F9 grabs ball on first hop and tries to beat BR to first for the force, BR gets there first, I make the "safe" call, still basically in the same position. Here comes the fun part. R1 has taken off for second when she saw the ball hit the ground, F9, after attempting the play at first, throws to F6 covering second in plenty of time, R1 slides into tag, I call the out.

My dilemna was this: After the play at first, the only thing I could do was pivot to second with the throw. I was directly behind R1 as she slid into second with no angle whatsoever and no time to step to one side or the other. Fortunately, R1 was out by so wide a margin, the blind guy in the top row of the bleachers could make the call. Any ideas as to what I could have done different?
