Of course, the answer to that question is a resounding NO. How unlucky could you be with the contract that Cain just signed? But, contract aside, I want to look at pitcher luck in terms of the results achieved for the quality of work produced. In other words, the relationship between wins and losses, and earned run average.
The traditional benchmark of W-L record for evaluating starting pitchers has now been largely eclipsed by ERA. Case in point is the 2010 AL Cy Young winner, Felix Hernandez, who took the trophy with a 13-12 W-L mark. Nevertheless, W-L is obviously still a prominent statistic. I can again cite Hernandez as a case in point – there was more than a little criticism of his Cy Young selection, based chiefly on that 13-12 record. Similar reaction attended Cain’s new deal. Even a knowledgeable blogger on this site pointed out Cain’s unremarkable career .486 W-L%, rather than his career 125 ERA+, ninth among active pitchers (min. 1000 IP), and in a tight cluster on that list with such names as CC Sabathia and Justin Verlander.
After the break, I’ll take a look at whether comparison of ERA+ and W-L% can provide clues as to whether a pitcher is lucky or unlucky.
