Line up mess in Tampa Bay

[SAump]

Would that make Longoria or Sorrenstine the improper substitute?
If Longoria is the pitcher of record, you cannot sub for him until he faces one batter. If this were the case, the visiting team lost the advantage in the top half of the inning. Blunder?

Batting "out of order" caught prior to incident and reported by the opposing team? The lineup card was wrong prior to the game. The determination was made not to allow a DH while the team was at bat. So the pitcher must have been missing from the offensive lineup. He was added to the lineup. The lineup was corrected. The game went on.

An illegal player? Longoria never stepped on the field of play as the pitcher, F5 or DH. Now had Longoria entered the batter's box in the 3 slot, would he not have become the pitcher of record {unless his manager called for a double switch}?

OBR 3.05(c) If an improper substitution is made for the pitcher, the umpire shall direct the proper pitcher to return to the game until the provisions of this rule are fulfilled. If the improper pitcher is permitted to pitch, any play that results is legal. The improper pitcher becomes the proper pitcher as soon as he makes his first pitch to the batter, or as soon as any runner is put out.
Rule 3.05(c) Comment: If a manager attempts to remove a pitcher in violation of Rule 3.05 (c) the umpire shall notify the manager of the offending club that it cannot be done. If, by chance, the umpire-in-chief has, through oversight, announced the incoming improper pitcher, he should still correct the situation before the improper pitcher pitches. Once the improper pitcher delivers a pitch he becomes the proper pitcher.

Again, why the player disqualification over a lineup error?
