What achievement is emphasized by the Chicago Cubs in promoting Kerry Wood?

The emphasis on Kerry Wood’s 19-strikeout game is significant because it highlights one of the most remarkable individual performances in Major League Baseball history. Striking out 19 batters in a single game is a rare achievement that showcases a pitcher's dominance and skill on the mound. This performance not only resulted in a record-breaking moment for Wood but also became a defining highlight, contributing to his legacy as an exceptional player. Promoting this specific achievement taps into the emotional and nostalgic aspect of sports fandom, as it represents a moment of greatness that fans remember vividly.

In contrast, while the other achievements listed might be notable, they do not carry the same level of impact or recognition as that spectacular strikeout performance. The 19-strikeout game stands out in the context of establishing Kerry Wood's potential and talent, making it a focal point for promotion.
