In an article in yesterday's editions of The Sun about Baltimore city schools, the name of schools chief Andres Alonso was misspelled. The article also incorrectly stated the portion of students in the city school system who had been held back. Nearly half of ninth-graders have been.

An article in yesterday's sports section incorrectly stated that John Unitas debuted against the Chicago Bears on Oct. 21, 1956. Though Unitas always talked of that game as his debut, and wrote about it in his autobiography, he played on Oct. 6, 1956, against the Detroit Lions and threw an interception.

A brief in Monday's Crime Watch section incorrectly stated the sentence Scott Ensor received for arson. He was sentenced to 30 months in federal prison.

The Baltimore Sun regrets the errors.
