(Tee Ball) Sudoku by mars / HAL 12000

(This post is part of: “A Story of Self-setting Sudoku”.)

Visual Score: (not relevant today)
Logical Score: 1/2 — adding a not so hidden hidden burst from one number but otherwise felt about the same as grids in the database.
Extra theme elements: 0/1 — none detected of note — pinch hitters is your whole strategy perhaps but what helps it describe this puzzle?
Unlisted category(ies): 0/2
Final decision would be to reject this submission, but given spring training we are sharing for overall team improvement.

Dr. Sudoku’s feedback: Showing a similar lineup is ok if that’s all you know how to do. First you have to catch up, then maybe you can be competitive. But don’t put a bad batter like #9 in such an early position of the lineup. It is so easy to defend what is coming with all the easy pop-ups and familiar plays.

Dr. Sudoku: You are an expert Sudoku maker who can do almost anything with Sudoku. Let’s start a game less like Tic-Tac-Toe (where the only way to win is not to play) and more like Tee Ball. Here the stakes are still low but we do need an opponent to bat against.
