Damion Easley has never played in a postseason game. If the Mets can manage to make the playoffs in 2008, it doesn't look like he'd be able to participate. The man is cursed.
Easley has played the most games in the league without playing in the postseason. My friend and colleague Andrew Beaton has a great post (two, actually) looking at Easley and his postseason-less run.
Easley may be out for a week, or even more with a tear in his hamstring. He suffered the injury legging out a double-play ball a few games ago, and hasn't made an appearance since.
What to do with second base? Well, it seems Luis Castillo has been delegated to the bench, so I guess he's not an option. Daniel Murphy has only seen limited time at second, and hasn't really impressed. That leaves the Mets with Argenis Reyes manning second for the stretch run and hopefully beyond.
Are you comfortable with A-Rey at second? He's a light hitter, like Castillo, but he doesn't look like he's in pain 99 percent of the time. He's quicker, and seems to have a good relationship with his fellow namesake Jose Reyes, as they can turn some pretty double plays.
The Mets will make the postseason in 2008, it's just too bad that Easley won't be able to participate. The curse continues.
