The Twins have won the bidding for Japanese middle-infielder Tsuyoshi Nishioka. This could be good news for the Giants, though.
Nishioka is said to be a better fit at second base, but the Giants are looking for a guy who can play shortstop well. In 2010, Nishioka posted a slash line of .346/.423/.482, but that was in all likelihood a big fluke, as he had a BABIP of .389... Before that, his previous best was .300/.366/.463...This article by Patrick Newman of Fangraphs basically likens Nishioka to Chone Figgins and Ryan Theriot, both of whom had unimpressive campaigns in 2010. So Nishioka isn't that great...throw in the fees for bidding and signing him to a contract, and it's definitely too high of a price to pay for a relatively weak shortstop.
The good news here is that this increases the likelihood that J.J. Hardy becomes available on the trade market. Hardy is one of the best shortstop options currently available: he's one of the best defensive shortstops in the majors, with a career UZR/150 of 11.0, and his bat has great offensive upside. From 2007-2008, Hardy belted a total of 50 home runs, although he hasn't come near those numbers in the past couple of seasons. However, his Bill James projections see him hitting .263/.328/.425 next year with 16 home runs. Throw in the superb defense that he'll inevitably provide, and that is an extremely valuable shortstop. Even with his .268/.320/.394 slash line in 101 games in 2010, he managed to produce 2.4 WAR. Project that over a full season and his 2010 worth is at 3.5-4.0 WAR. But he's projected to improve upon those numbers. At this point, the Giants probably wouldn't even have to give up much to get him.
His excellent defense and significant offensive potential warrant serious consideration. A lineup of Buster Posey, Aubrey Huff, Freddy Sanchez, J.J. Hardy, Pablo Sandoval, Mark DeRosa, Andres Torres, and Cody Ross is a legitimate offense. Pair that with the incredible rotation that the Giants have, and I think they have the tools to win many games. And that's not even considering the eventual call-up of Brandon Belt.
