		<description>Nick,  
maybe there are 2 different FIP formulas??? but the one Im aware of is FIP=(HR*13+(BB+HBP-IBB)*3-K*2)/IP + 3.2.  My point was that this formula doesnt translate well among different eras.  There werent nearly as many HRs hit in the 60s 70s 80s as there were in the 90s and 00s, which is probably the single most relevant factor fot this discrepancy.  The FIP numbers for MLB is close to the actual ERA for MLB in the late 90s and 00s, but way off in other decades.

Top2124,
Im completely aware the author meant those pitchers throw hard, thus have high Ks, hence my comparison to saying players who have a lot of hits will have high BA.

See, when a formula is highly based off of a stat (as in FIP and Ks or BA and Hits), its kinda redundant to say that players with a lot of the component of the stat (K or H), will have a very good stat (FIP or BA).</description>

		<description>Judging by last year and the start of this year, Kubel and Span are both above average hitters.  Now with Mauer back, they&#039;ve gone from dreadful to just bad.</description>

		<description>Speaking of patience, the big news &lt;i&gt;this&lt;/i&gt; week is going to be that Yuniesky Betancourt finally drew a walk, leaving Bengie Molina in sole possession of the &quot;no free pass&quot; club.  Though it took 97 PAs for Yuni to finally watch four balls go by, so Bengie still has 6 more to go.</description>

		<description>Andy was once a top prospect, with a great hitting approach and a good glove, and he is still pretty young.  Obviously we shouldn&#039;t expect him to be Longoria-esque, but that is certainly his potential.</description>

		<description>And he was citing that they throw hard, which is the reason they rack up strikeouts, thus having low FIPs.</description>

		<description>When are we getting a column about Ryan Braun and his patience?  His walk rate went up each month last season--culminating over ten is September--and this year he&#039;s been Pujolsian.</description>

		<description>That is probably because the spread in defensive talent was a lot wider back then.  FIP is completely dependent on normalized BABIP, and if you have one player allowing a .400 BABIP and another one allowing a .250 BABIP, then obviously FIP won&#039;t match ERA.</description>

		<description>I actually think that Morneau had been pressing to create &quot;something,&quot; seeing as how he&#039;s the only above average hitter (along with Span, potentially) in that dreadful lineup.  Lord knows Michael Cuddyer and Delmon Young aren&#039;t going to carry the Twins . . .</description>

		<description>citing that the best FIP pitchers are those who have high K&#039;s is kinda redudant seeing as FIP is strongly correlated to K.  Thats almost like saying the the players with the most hits are going to lead the league in BA.

has anyone else noticed that the FIP formula only correlates to ERA in the last 10ish years?  If you go back to the 70&#039;s or earlier, the numbers are way off.</description>
