07:36 AM ET 01.15 | Dave Dombrowski may be about to watch his clean slate muddied a bit in one regard. The Detroit Tigers haven't had a case reach arbitration since [Dombrowski] took over as general manager in 2002. He'll have his hands full the next few weeks if he intends to keep his perfect record intact. Max Scherzer and Rick Porcello were among six Tigers players who filed for salary arbitration Tuesday, as expected, after being unable to work out long-term contract extensions. ... Scherzer, 29, is in his final season before free agency and is expected to command a significant pay increase. The reigning AL Cy Young Award winner is projected by mlbtraderumors.com to make $13.6 million in his third and final year of arbitration eligibility -- an estimated salary increase of $6.8 million after earning $6.725 last year.
