Happy Luis Castillo-Might-Be-Back Day! The polarizing starting pitcher fired seven shutout innings against the Brewers on Tuesday with seven strikeouts. Once drafted as a top-10 starting pitcher, he had fallen outside the top 30 at his position in our most recent rankings updates. This is now a three-start stretch where Castillo has a 1.98 ERA. I don't think he's fully back to the ace we've seen in the past, but I think we're getting closer.

Castillo wasn't the only impressive pitcher on the mound Tuesday as Taijuan Walker, Patrick Corbin, Dallas Keuchel, and Frankie Montas all turned in quality starts. I owe an apology to Walker, who I recently said you should try and trade for anything. Boy, was I wrong. Walker struck out a career-high 12 batters over seven innings on Tuesday and has now allowed one walk or less in six of his last eight starts. If he can keep this level of control up with generating soft contact, he may be on to something.
