The news out of Philadelphia is that the Phillies want to persue free agent outfielder Alfonso Soriano. Presumably they would trade Pat Burrell to open up left field. Soriano has long been looked at in the sabermetric community as an overrated player, even a bad one. At some points, that flies in the face of logic. What do we make of Soriano? Is he a promising player into his 30s, or a potential liability?

Soriano's comparables at his age include Howard Johnson, Tony Batista, Matt Williams, Bob Horner and Jeff Kent. Howard Johnson is an interesting case. Like Soriano, Johnson had a huge year at age 30, hitting 38 home runs and stealing 30 bases. Johnson hit .233 the next season with 7 home runs. Ouch. Still, you wonder how accurate the comparisons are given that Soriano didn't get started until he was 25, now plays left field, and has plate discipline unlike most of his comparables.

Using Lee Sinins' sabermetric encyclopedia, I sought to create a new group of comparables. I asked the program to give me a list of all players who hit 150 home runs, stole 150 bases, and produced an OBP between .315 and .340 (Soriano's is .325). The list produced fifteen players, one of which is Soriano. That leaves us with 14 comps. Let's take a look at them, purely after age 30.

EXCELLENT: Andre Dawson

VERY GOOD: Dave Parker, Steve Finley, Dante Bichette

GOOD: Bill Buckner, Ron Gant, Devon White

FAIR: Vada Pinson, Juan Samuel, Raul Mondesi, Claudell Washington

POOR: Marquis Grissom, Lloyd Moseby, Howard Johnson

Dawson made five all-star teams, Bichette and Parker made three, and Finley two. Except for Dawson, none were truly great players in their 30s. Most players remained productive well into their careers though. We would expect players with high stolen base totals to remain good later on, as truly athletic players at 50% are still good athletes. What's interesting is that Soriano has a higher isolated power figure than any other player on the list.

Going forward, it's difficult to tell what to expect. Players of Soriano's caliber don't remain stars, but Soriano's such a unique player that he may buck the trend. You hope that the Phillies (or any team) have him scouted well, and have taken the stats into consideration.
