Masanori Ishikawa started the season with four losses in his first four consecutive starts (5.47 ERA, 1.66 WHIP). He then lost two more games over his next five starts before recording his first victory of the season on 5/29 (2.59 ERA, 1.13 WHIP). Over his next 5 starts, Ishikawa would go 2-2 (4.35 ERA, 1.31 WHIP) to bring his record to 2-8. And since then, Ishikawa has won each of his starts to go 6-0 (2.43 ERA, 1.33 WHIP).
At one point in the beginning of the season, it seemed as if it would be near impossible for Ishikawa to turn things around enough to finish the season with more wins than losses, but as of now, he's 8-8 in 21 starts.
Incidentally, the 6-game winning stretch he's on right now, matches a career high.
(And yes, I know the Dickens quote is backwards.)
