• SynonymピッチャーNeutralLoanword for the same position; common in casual talk and game broadcasts. 「投手」 is the more formal term, seen in news and records. In speech it can replace the headword.
• Antonym打者だしゃNeutralThe batter — the role opposite to the pitcher on offense and defense. An antonym, not a substitute for the headword.

For the pitcher in formal contexts — news, records, compounds like 「先発投手」 — use 「投手」; 「ピッチャー」 is the everyday word in casual talk and broadcasts. 「打者」 is the antonym: the batter, the opposing role.
