Marcus Thames: HR Machine

If you haven't noticed by now, Tigers OFer Marcus Thames is on fire. His last 7 hits have all been homers and he's now up to 12 HRs in just 113 ABs. This follows an 18 HR performance in 269 ABs last year and 26 HRs in 348 ABs in 2006. That's a total of 56 HRs in 730 ABs the last 3 years, or a HR every 13 ABs and a 46 HR pace over 600 at-bats. With a chance for every day at-bats, can we expect this kind of power production going forward and what kind of value can he provide in various league formats?
