A long-time presence in the two slot, Derek Jeter has found new life at the lead-off position in recent seasons. The issue with Jeter is that his average is down, and he still only has two home runs courtesy of his May 8 performance against the Texas Rangers.
In the second slot, however, Jeter tends to hit into a lot of double plays. The lack of power forces Jeter to avoid the middle of the lineup, but his OBP is only .319.
Although it may never happen because of Jeter's status as captain and his importance as the face of the Yankees, Brett Gardner's current OBP is slightly better, with higher slugging, and a similar average, thus he could be a worthy replacement for the lead-off spot. At the very least, he could take the role more frequently.
Gardner has made 47 plate appearances in the first slot in the lineup this season. His speed is impressive, as is his ability to score runs, particularly for someone who frequents the bottom of the lineup.
