A misspelling (nigsource.htmare) and an incorrect date for Cone's 19K game. The date for Cone's 19K game is correct on the log below David Cone's biography, it is just incorrect in the written biography.
Original text:
"Cone was a batter's worst nigsource.htmare, some nights needing only his 90+ MPH fastball to dominate an opposing lineup. His real strength, however, lay in his command of an array of pitches and his ability to throw them at a variety of speeds. At any point in an at-bat Cone was capable of pinpointing a cut fastball, slider, curve, changeup, or his lethal split-finger, which he used as his out pitch. At times he seemed able to invent pitches on the spot when the situation demanded. "David knows how to get guys out even when his arm feels like crap," said Yankee teammate Tino Martinez. "Sometimes, his stuff looks terrible out there, but he keeps putting zeroes on the scoreboard." With such a deadly arsenal at his disposal, Cone led the major leagues in strikeouts three straight years from 1990 to 1992. On September 10th, 1991 he tied a National League record (since broken by Kerry Wood) when he fanned nineteen Philadelphia Phillies in a nine-inning game."
