The Giants are reportedly looking at Fields as a third base alternative to Rusty Ryal, who has really struggled this year. None of Yomiuri’s homegrown options seem to have the chops for the hot corner.
While the author of the article believes a .365/.429/.674 line is great, those numbers need to be broken down. Triple-A Colorado Springs is launching pad as it doesn't have humidor and is at even higher elevation (6,531 feet) than Coors Field. At Security Service Field, Fields is hitting .425/.462/.811 with 12 doubles, 1 triple and 9 home runs. But on the road he is hitting .278/.384/.472--not bad, but not great.
If Fields was that great of a third baseman this season, then the Rockies would likely have promoted him at some point earlier this season to at least try to fill in for the third base gap that Ty Wigginton has subsequently filled.
If this happens, it's not much of a loss.
