ESPN.com's Buster Olney takes a look at six free agents who might not be on the Hot Stove marquee, but should draw plenty of interest this winter.  In his opinion, Juan Cruz might end up being the most pursued pitcher, based on the demand for relievers and the numbers he put up last season.

He also thinks Cruz could be a great fit in Detroit. 

[...] there is such a scarcity in the relief market for someone like Cruz that it figures somebody will gamble on him, in the way the White Sox gambled a four-year deal on Scott Linebrink last winter.  Some rival officials think that he fits the immediate needs of the Tigers.

Just to remind everyone, Cruz threw 71 strikeouts in 51 2/3 innings last season for Arizona.  (His record was 4-0, with a 2.61 ERA.)  That works out to 12.8 Ks per nine innings.  And 71 was actually the lowest number he's had in three years.  In 2006, Cruz punched out 88 in 94 2/3 innings.  In 2007, 87 Ks in 61 innings. 

Walks are a concern, as he's averaging almost five per nine innings.  Maybe that doesn't quite mesh with the new Rick Knapp "throw strikes" philosophy.  But maybe Knapp could do a better job of harnessing Cruz's heat than other pitching coaches have done in the past. 

I already made my argument for Cruz back in August (and will probably link to that frequently until he decides which team he'll sign with).  And though there are some rumblings that the Tigers might be interested in Brandon Lyon for their bullpen, it seems pretty clear that the other Diamondbacks pitcher should be their guy.
