Tagged with another loss
Castillo (0-4) was tagged with the loss Saturday against the White Sox, allowing four runs on five hits across four frames. He struck out six.
Análisis
This loss against Chicago ballooned Castillo's woeful ERA to 6.57 across 38.1 innings in eight outings this year. He's lost his past three starts and has given up at least four runs in each of those games. Castillo has been confirmed to start Thursday against the Astros, but according to Ryan Divish of The Seattle Times, after that the Mariners plan to piggyback him with Bryce Miller in the rematch series against the White Sox that runs May 18-20.

Could get bumped from rotation
The Mariners could remove Castillo from the rotation when Bryce Miller (oblique) returns next week, Adam Jude of The Seattle Times reports.
Análisis
It's just one option the team is mulling, as Miller and Emerson Hancock are also being considered for the bullpen or piggyback roles. It would be an easy decision to bump Castillo from the rotation if it were based purely on performance, as he's posted a 6.29 ERA, 1.66 WHIP and 31:13 K:BB over 34.1 innings in his first seven starts. However, Castillo has never pitched in relief at the major-league level, while Miller and Hancock both have. A six-man rotation is also under consideration. Castillo will start Saturday in Chicago against the White Sox in what could be his final opportunity to convince the Mariners he should remain in the rotation.
