Marking the milestone, here's the final card I picked up (at the Chicago National in 2005) to complete the base set:
Card #590 -- Deron Johnson, Philadelphia Phillies
Johnson moved around often during his playing days, and 1973 was no exception. He was traded to Oakland a month into the season, which meant he immediatey went from a developing team to a contender. He managed to win a World Series title with the A's, something he didn't get do enjoy as a Yankee early in his career. As his career wound down, Johnson would be picked up by the Red Sox to help them in their '75 pennant drive after Jim Rice was injured, but it was too late to qualify for the postseason roster. As a result, that '73 Series ring would be the only one Johnson managed to earn.
When the A's picked up Johnson in 1973, it was one of the first times a team specifically looked for a player who could be a full-time designated hitter. Since it was the first year of the DH rule in theAmerican League, few had considered the value of going after a player whose field time was limited due to injuries and age. While it's a common thing today, Johnson was one of the first to fill that role.
After retiring in 1976, Johnson would go on to become a minor league manager and coach a number of major league teams through 1991. Sadly, he was diagnosed with lung cancer that year and died in '92.
