He's still obviously a second division starter and better used as a backup.
His play aside from his baserunning has been much better this year. Whether it's OPS, OPS+, wRC+, OBP, or LD%, they've been solidly above average (OBP), average, or slightly above. His offense has done a complete 180 from last year. (Yes I know looking at his traditional stats doesn't say as much).
That said, the real point I am trying to make is that even with all the praise (internally or otherwise), I hope the Mets realize that both Tejada and EY (who you can also include) are still better bench assets, given this teams needs. You want to make a team better? Then transition those guys to where they see spot playing time, are still very useful, and bring in better everyday regulars at those positions.
