The answers to the following game situations and The Rule number as well. 

Case No 1. The starting pitcher replaced before taking mound!
In the top half of the first inning, the visitors go on a run-scoring spree and lead, 7 - 0, when their starting pitcher is due to bat. The manager decides to save his starter for the next night and let a rookie pitcher inherit the big lead. He sends in a pitch-hitter. IS THIS LEGAL??

 

Answer:  Umpires must not permit a pinch-hitter for a starting pitcher who has not yet taken the mound.  The announced pitcher must bat and then pitch to at least one batter before being replaced. (Rule 3.05 a)

 

Case No 2. Warm up pitchers permitted in emergency!
In the seventh inning, the starter suffers a pulled muscle in the pitching arm and cannot continue. The team has no pitcher ready in the bullpen. What is the proper procedure??

 

Answer:  When an injury or other emergency necessitates bring in a new pitcher cold, the umpire-in-chief is obliged to allow him as many preparatory pitches as the arbiter deems necessary for the hurler to get ready.  Normally the umpire will permit the pitcher to warm up until the hurler indicates he's ready (Rule 8.03)

 

Case No 3. The third strike contacts the batters uniform!
With a count of two strikes, a fast ball pitcher breaks off a sharp curve. The batter, expecting a fast ball, misses, but as he swings the ball nicks his uniform shirt. Meanwhile, the runner on first steals second base. What is the Ruling??

 

Answer:  While attempting to hit a third strike, a batter is out even though the ball strikes him.  The ball, however, becomes dead when it hits the batter or his clothing and therefore the runner cannot advance leagally and must return to first base.  (Rules - 6.05f, 5.09a, 6.08b - Approved Rulling)

 

Case No 4. Ground ball nicks outside edge of base!
A hot grounder nicks the outside edge of first base and bounces into foul ground. What is the Ruling??

 

Answer:  Fair Ball. First and third bases should be placed within fair territory and any ball striking any part of either is fair.  (Rule 2.00 - Fair ball)

 

Case No 5. Bunt spins back onto home plate!
Attempting to sacrifice, the batter bunts foul, but the ball with reverse English spins back toward home and stops on the plate. FAIR or FOUL??

 

Answer:  Fair.  Home plate is in fair ground.  (Rule 2.00 - Fair ball)
