1. Not sure. But I do know the line went from corner to corner when it split the bag. Just curious - why do you want to know?

2. No. The new layout eliminated the "perfect diamond" or square. The diamond is now a bit out of whack geometrically (technically speaking).

chris,

Technically speaking, the rule book infield is STILL a perfect geometric square.

What throws some people off is that the pitcher's plate is NOT on the diagonal.

No, the infield is a perfect square - by rule. The actual base is the point on the ground at the corners of the square.

See 1.04 When location of home base is determined, with a steel tape measure 127 feet, 3⅜ inches in desired direction to establish second base. From home base, measure 90 feet toward first base; from second base, measure 90 feet toward first base; the intersection of these lines establishes first base. From home base, measure 90 feet toward third base; from second base, measure 90 feet toward third base; the intersection of these lines establishes third base.

Home plate and the bags are markers for the bases, and are positioned differently at the different corners.

1.05 Home base shall be marked by a five-sided slab of whitened rubber. . . It shall be set in the ground with the point at the intersection of the lines extending from home base to first base and to third base;

1.06 First, second and third bases shall be marked by white canvas bags, securely attached to the ground as indicated in Diagram 2. The first and third base bags shall be entirely within the infield. The second base bag shall be centered on second base.
