I still think Melvin is a poor in game manager.  It's hard to pull up every instance, but last night immediately comes to mind.  Putting in Clark as a defensive replacement for Jackson in the 7th is asinine considering:
1) Jackson is just as good a defensive player as Clark at this stage in their careers.
and
2) Webb would be departing the game soon and, with a slim 2 run lead you could use Clark to PH for Webb (Clark being a major upgrade over who he used: Cirillo).

Not to mention the fact that Jackson was 1-2 with a HR and two walks in the game.  Clearly he was seeing the ball well.

Onto pitcher management: it's well documented Melvin has a tendency to keep pitchers in 5 innings, no matter what, just so they can have a chance at the W.  This strange (but not uncommon) quirk is always irksome.  Melvin tends to leave his set-up pitchers (Pena especially) in a little bit too long, and he has a tendency to underwork Slaten, treating him like a true lefty specialist, when he has shown the ability to pitch to both righty and lefty batters.

Onto lineup construction.  I actually like how much Melvin moved hitters around, especially on a team like this.  My only gripe is that CY should have never been hitting in the 1 hole.  Other than that, there's not too much to complain about.

Onto the good: it seems clear over the course of the season that Melvin has a remarkably steady hand when it comes to managing the personalities on a team.  And there are definitely some very large personalities on this team that could have caused tension: Valverde, Byrnes, Hudson, RJ, CY.

Melvin seems to do a good job of creating a loose atmosphere where the guys can operate while also instilling a basic level of respect and hustle into his players.  That's a hard combination, but I think he's managed it well.

Melvin will win the MOTY and I will certainly not begrudge him it.  He's done very well.  I just hope he can continue to develop as an in game manager.
