pitch in

They told me I could pitch again in six weeks.

He pitched in the first $5,000 and asked others to help.

He pitched in his last game on May 9, 1966.

He pitched in 36 games and started 20 of them.

State and local officials pitched in nearly $1 million for the effort.

Or does he care more about pitching in a big city?

They are the group that has pitched so well in recent months.

He could pitch in a game next weekend, if everything goes right.

He started three times, and pitched complete games in two of them.

I pitched in some games that shouldn't even have been played.
