What kind of lineup is that? If similiarity scores have merit, it is a similar lineup to one posted by the Philadelphia Phillies down the stretch. Similarity scores seek to compare two players' statistics and measure their comparability. A score of 1000 would indicate two players who are exactly alike. Scores under 900 indicate players who are not very similar. Bill James developed the concept as a way of judging Hall of Fame arguments. Thanks to spreadsheets and computers, statisticians can instantly compare thousands of players to determine which players are MOST comparable. Baseball-Reference.com has taken the concept further, using similarity scores to measure players at specific ages. Miguel Cabrera is currently most comparable to Hideki Matsui. But if you compare him to other players when they were 23, Henry Aaron appears at the top of the list (as he has the last three years). This is a good omen for Cabrera's career.

 

Looking at a list of players comparables can give us an idea of what to expect from a player's career. A player with a lot of All-Stars and Hall of Famers is a good bet to continue to have a Hall of Fame career. Some players might have a mix of HOFers, and guys who flamed out early in their careers. If no players similar to a certain player produced much after that point in their careers, we would expect caution. With that in mind, let's take a look at the 2006 Phillies still under contract, and see what we might find.

 

Understand that when I look at comparables, I am looking at what they did AFTER the age of the player to that I am comparing. Also, Similarity Scores are NOT era adjusted.

 

C: Carlos Ruiz. Ruiz has only played 69 games in his career, so there is no comp list available. A list of players who played 69 games at the age of 27 would likely contain plenty of scrubs, but that's not entirely fair. You just can not draw a good list with too little data. The same holds true for fellow catcher Chris Coste. Free agent catcher Mike Lieberthal's best comps are Jason Varitek and Terry Steinbach. On average, Lieberthal's top ten comps played two more reasonably productive seasons.

 

1B: Ryan Howard. Howard's best comp is Norm Cash, an intriguing choice. Ryan Howard at the age of 26 hit 58 home runs. Norm Cash hit .361 with 41 homers, a huge fluke season later attributed to corked bats. Cash produced well into his late 30s hitting 20-30 home runs a season in an era where that reached the top ten.

 

2B: Chase Utley. Utley's best comps are Alfonso Soriano, Jeff Kent, Marcus Giles, Vinny Castilla and Pedro Guerrero. All of Utley's comps had huge careers with the exception of Giles, who still has time to rebound from a dismal 2006.

 

SS: Jimmy Rollins. Rollins' best comps are Jim Fregosi and Alan Trammell. Trammell had a great career. Fregosi flamed out early, but not before the Angels dealt him for Nolan Ryan. Rollins more than any other player has a big boom/bust quotent in his comp list. Along with Ryne Sandberg and Lou Boudreau, it includes weak hitters like Zoilo Versalles, Frankie Crosetti and Granny Hamner.

 

3B: Abraham Nunez. Nunez's best comp is Billy "F.F." Ripken. Ripken was an awful hitter. The only player on Nunez's list to hit above league average was Dave Anderson, who had 84 at bats left. The Phils desperately need an upgrade here.

 

LF: Pat Burrell. Burrell's best comp is Gil Hodges, a perennial Hall of Fame candidate. With respect to Hodges, this says more about why he isn't a HOFer. Most of Burrell's comps had 5-7 more years left, hitting about 10% above league average. I doubt that's worth $13.5 Million a season, but the Phils can live with that.

 

CF: Shane Victorino. Alex Ochoa, a player probably seen as an also-ran but was also a terrific fourth outfielder for a few years. Ochoa played five more years hitting league average. With Victorino's defense, that's a big plus.

 

RF: Aaron Rowand. Carl Everett. Fortunately this measures production and not attitude. It's difficult to get a read on Rowand's comp list because there are many current players on the list. Most of the others were league average hitters who played 5-6 more years.

 

SP: Brett Myers. Myers best comp is Brad Radke, who went 94-85 over the next eight seasons. Frank Viola is the best player on Myers' list, Sammy Ellis is the worst. No Hall of Famers, but a few All Stars.

 

SP: Jon Lieber. Lieber's best comp is Kevin Tapani, a player who finished 9-14 for the 2001 Chicago Cubs and then retired. Second is Shane Reynolds who didn't pitch past 37, third is John Burkett (25-17 over two years), and Charles Nagy (retired). Jamie Moyer is seventh on the list, and no other pitcher lasted more than two more seasons. The Phils only need one more good one.

 

SP: Cole Hamels. Hamels' best comp is Floyd Bannister, the father of Mets' pitcher Brian. Floyd pitched league average ball for 14 seasons. There are some good pitchers on the list, no real stars, but that's what you get with 23 starts. This list would look better if Hamels improves next year.

 

CL: Tom Gordon. Gordon's best comp is Charlie Hough, which seems a little. Gordon throws gas and a wicked curve from the bullpen. Hough threw a knuckleball. Gordon started and converted to the bullpen. Hough started as a reliever and converted to starting.

I feel bad for Jason Kendall that his #1 comp thru age 32 is still Thurman Munson which obviously means Kendall is going to die soon.

Until 2002, Kendall's top comp was Mickey Cochrane, who was nearly killed by a pitch in 1937. What strikes me about Kendall's list though is that it contains only three catchers. There's a positional bonus put into these things. Kendall is one of the most unique players in baseball today.

I thought it might be kind of interesting to look at who's #1 on the similarity score list of this year's top rookies, not that it means much.

 

Hanley Ramirez - Jimmy Rollins (#2 Derek Jeter)

Francisco Liriano - Al Downing (#6 Whitey Ford)

Justin Verlander - Clark Griffith

Ryan Zimmerman - Ken Keltner (#2 Ron Santo)

Jontahan Papelbon - Dave Smith (#8 Jeff Reardon)

Dan Uggla - Charlie Irwin (#5 Chase Utley)

Jered Weaver - John Fulgham (#5 Luis Tiant)

 

Verlander and Uggla are OLD SCHOOL~!

Ramirez has three HOFers plus Derek Jeter on his list. That's a great sign.

 

Weaver's #2 is Ed Walsh. 40 wins here we come!

 

If Bonds end up in the AL it's possible that Liriano could give up HR number 756.

 

The Zimmerman test will replace the Keltner Test.

Zimmerman > Keltner

 

Keltner produced that line in a hitters' league. Zimmerman plays in an extremely tough hitters' park. Both were excellent defensively though, so it's a great comparison.

Liriano's comparisions aren't that great. Only one HOF player.

I'm not sure if that's sarcasm or not. There are some very good players on there. You're not going to get very accurate assessments for just half a season though.
