1 umpire position on calls at first

[Lancerdad]

I call Little League 11 and 12 years olds on my own. Last night batter lays down nice bunt between F1 and F2. I follow R1 down the line F1 makes throw to F3 was kind of blocked out on play and called runner safe. It was one of those calls that you know you blew but had to stick with. Luckily R1 did not score so no effect on close game (4-1). After the game one of the coaches who has umped a little said I could get a better angle on that kind of call by drifting more towards second. I appreciate any help for this 2nd year rookie ump!

Thanks,
