ESPN SportCenter highlights from May 6, 1998.  The Cubs’ 21-year-old pitching phenom Kerry Wood strikes out 20 in one of the most dominant pitching performances of all time – and against the winningest Houston Astros team ever. Check out the break on the slider he throws around 1:30 – it broke so hard it crosses the plate and ends up behind the hitter! That year, he pitched 167 innings and struck out 233 – almost 1.5 an inning. His elbow would later revolt.
