What makes a great rookie pitcher season

Immediate command

The best rookie pitchers do not look overwhelmed. They throw strikes, work ahead in counts and keep their nerves under control. Command makes the difference between a promising arm and a true breakout star.

A rookie who can miss bats is usually ready for big things. Strikeouts show that the stuff works at the highest level and that hitters cannot simply wait out the pitcher.

Durability through the season

It is one thing to flash for a month. It is another thing to hold that level for a full season. The great rookie campaigns stay strong from start to finish and often get better as the year goes on.

Impact on the team

The best rookie seasons help win games and change a club outlook. A young pitcher who becomes a staff leader right away can shift the whole direction of a season.
