Straight off the bottom of Diamond Challenge page 2 comes this humdinger:

You know the drill --

Read the full size version of this comic and share your call. When you post, I encourage you to reference specific rule(s), precedence or if you witnessed a similar situation on the field. 

To make this game a little more "interesting", I will throw in a pair of tickets to the game on Monday, Sept 26th vs. LA Dodgers (transportation not included) to the person who has the quickest, most accurate & complete calls over four challenges (2a, 2b, 3a, 3b)  in comparison to the one published in my nifty Diamond Challenge book. 

The decision for this challenge cites also cites two specific rules. Good Luck!

For a bit of background ...  the Anatomy of a Rule:

Example, 7.06(a) 

7 identifies the Section (Runner)

.06 identifies the Sub-Section (Obstruction)

(a) identifies the Provision (Specific Play)
