Answer:
"I can throw more accurately than our team's other pitcher."
Explanation:
"Accurate" is one of those words that doesn't work with the -er and -est endings that many adjectives have. Because you're describing a verb (throw), you would turn "accurate" into the adverb "acurrately."
You're comparing your pitching skills to only one person, the other pitcher on the team, so you would use "more." You would use "most" when comparing yourself to everyone in the group.
Example: "I am the most accurate pitcher on our team."
