The 2006 Yankees lineup was quite deep. Of the seven players who made at least 500 plate appearances, only one had an OPS+ below the league average 100. They had the reigning AL MVP in Álex Rodríguez, and a guy who came very close to winning MVP (and arguably should’ve) that season in Derek Jeter.
That’s not to say there weren’t holes, however. Due to injuries and a lack of production in general, one of those holes was in right field. As it just so happened, a pretty good right fielder was available, and would end up helping the Yankees to a ninth straight AL East crown.
