I have for sale the Twins' dugout lineup card (large one) from 4/7/00 Twins @ Royals. I believe this was Johan's first career major league start. From Wikipedia:

"He made his first MLB start on April 7, 2000, at Kansas City and recorded his first Major League win in a relief appearance at Houston on June 6."
Excellent condition - $500 OBO. Email me if interested.
