Dirt Covered Plate

[njdevs00cup]

R2 & R3 infield in. Batter hits a one hop shot to F3 who makes a terrible throw home. R3 slides in completely covers home plate with dirt. The ball goes to the backstop and F1 does not cover the plate. R2 does not break stride and slides into the dirt covered plate as F2 dives to attempt to tag him out. Naturally it was a bang, bang play. I tried to use the remaining chalk from the left handed batter's box as a point of reference as to the location of the plate, saw a late tag (hip high), walked around to the front of the plate to see R2 on the plate and called him safe. Any feedback?
