Chase Whitley fired 7 2/3 innings of two-run ball Thursday in a 6-3 victory over the Mariners. Whitley continues to hang on as a surprising fantasy contributor, and he's doing it by not committing unforced errors. He struck out six tonight, but, more importantly, he didn't walk a batter for the fourth consecutive start. The former 15th-round pick, a converted reliever, is leaning on a continually improving slider to keep batters off balance. Whitley improves to 2-0 with a 2.41 ERA, 1.01 WHIP and 24/3 K/BB rate in six starts, but three of those outings came in NL parks, and the other three were at Seattle and Kansas, and a home date against a pre-Kendrys Morales Twins. By all means deploy him in AL-only leagues, but there are better options out there in standard mixed leagues. Whitley squares off against the Blue Jays on Wednesday.
