08:27 AM ET 03.25 | The Joba rules are now giving way to the Joba lessons. With Joba Chamberlain heading back to the eighth inning, what can the Yankees learn from his handling to apply this year to Phil Hughes? The soon-to-be-named No. 5 starter will have innings restrictions in 2009 just as surely as Chamberlain did in 2008, when he was the No. 5 starter. Chamberlain was permitted to throw 163 1/3 innings between the regular and postseason after amassing 100 1/3 the year before. Hughes worked 110 1/3 innings last season, including the postseason. So expect Hughes to be allowed roughly a 50-60-inning increase, which would mean a 170-inning maximum.
