It's no question that Placido Polanco's struggled with the bat this year. Judging from his advanced numbers, it's a bit luck (low batting average on balls in play [BABIP]), but part of the low BABIP is due to hitting about 3% more fly balls than normal.
But, that aside, is it time to move him down in the order? He's at
-5.7 Weighted Runs Above Average this year at the dish. Polanco's value with the bat is tied in his abilities to hit .320 or better because he doesn't walk much (just 5.4% of his plate appearances) but he also doesn't strikeout much (7.1% of all PA's). He also doesn't hit for power (.112 Isolated Power), so he's a guy who needs to hit for a high average to allow the few walks he does take to bump his on-base percentage into a reasonable state.
This year, he's hitting just .263 entering play this afternoon and that leaves his OBP at a measily .317. His normally higher average also bolster's his slugging percentage over the .400 mark normally, but due to his bad average, he's fledgling at .390.
The way I'm going to analyze the lineup is through
David Pinto's Lineup Analysis tool over at Baseball Musings. The
most used lineup for the Tigers in 2009 has been:
Granderson
Polanco
Ordonez
Cabrera
Guillen
Laird
Inge
Raburn
Everett
The Birchman brought this up in the comments, and proposed the following lineup:
Clete
Guillen
Cabrera
Granderson
Thames
Inge
Polanco
Laird
Everett
Now, I don't like Guillen in the 2 spot. He's struggled at the dish this year, so I'd put Inge (yes, even with his struggles) in the 2 spot.
How do these lineups stack up against each other and what would be the optimal lineup with both sets of personnel? Glad that you asked...
The most common lineup for Detroit
would average 4.652 runs per game. Coming into this afternoon's tilt with the Baltimore Orioles, the Tigers had scored 488 runs in 106 games, for an average of 4.604.
If you extrapolate their actual rate of runs scored, you get 746 runs per 162 games. If you use the most common lineup would score about 754 runs over the course of a season -- remember, this doesn't count days off for guys or account for injuries, so that's the reason for the discrepancy. The Tigers have just 55 games left after today's series finale, which would mean if they used their most common lineup every game for the rest of the year, they would score around 256 more runs this year.
Now, if they employed the proposed lineup, they would
average 4.792 runs per game. Extrapolate that over an entire season (a.k.a. everyone in that line up play 162 games, which isn't reasonable), you get 776 runs scored -- some 30 run improvement (or, about 3 wins worth). Now, just for simplicity's sake, the most common lineup averages 4.652 but the Tigers have averaged 4.604 which is a difference of 0.048 runs between the two for injuries and resting players. So, let's take that off of this lineup's projection and you now get 4.744. That comes out to 769 runs -- so just about 7 runs slashed from the 162 game average. Over the next 55 games, your'e looking at 261 runs scored which is just about 5 runs (half a win's worth) over the most common lineup.
But, that begs the question, what would be
the best lineup?
Well, for the most common lineup Detroit's used this year,
it'd be:
Cabrera
Inge
Ordonez
Polanco
Granderson
Raburn
Everett
Guillen
Laird
That batting order would score 4.814 runs per game and 780 runs -- a 4 run improvement over our proposed (and better) lineup. But, subtract the 0.048 for reserves/injuries and the best lineup using these nine would be 4.766 runs or 772 per 162 and 262 the rest of the way.
Using the proposed batting lineup, the most optimal one would be:
Cabrera
Inge
Laird
Thames
Clete
Granderson
Polanco
Everett
Guillen
And that lineup would produce 4.888 runs per game (792 per 162 games). Over a 55 game span the rest of the way, that lineup would produce 269 runs. Subtract 0.048 runs per game, though, for reserves/injuries over 162 games and that becomes 4.84 R/G which is 784 runs in 162 games and 266 runs the rest of the way.
For what it's worth, the most common lineup, if rearrange to score the fewest runs possible, would include this order:
Everett
Laird
Granderson
Guillen
Raburn
Ordonez
Inge
Cabrera
Polanco
And they would average just 4.369 runs per game (708 per 162/240 rest of the way).
And for the proposed lineup, the worst order would be:
Everett
Laird
Granderson
Guillen
Polanco
Clete
Inge
Cabrera
Thames
And that lineup would score 4.442 R/G (720 per 162/244 the rest of the way).
The results aren't that dramatic for the most common and the proposed lineup's (about 4 runs), but any little bit helps in such a close division race.
