According to the Win Shares calculations by the good folks at The Hardball Times, Geovany Soto leads all Major League catchers in WS, placing just ahead of the Twins' marvelous Joe Mauer. Dave Studeman also points out that Soto has nailed 38% of the runners attempting to steal against him while making just one error.
As pointed out at cubs.com, Alfonso Soriano has hit safely in 12 of his last 13 games. True enough, but in the same 13 games, Fonsie is hitting .250 overall with a .298 OBP, a .423 slugging percentage, and 12 strikeouts in 52 AB.
If Soriano keeps a scrapbook, I'm thinking that none of these past 13 games are likely to find their way onto any of the pages.
