D-backs put Blake Walston (elbow) on 15-day IL
Diamondbacks placed LHP Blake Walston on the 15-day injured list with left elbow inflammation.
Advice: Walston ascended to the majors earlier this year and has pitched well for Arizona with a 2.84 ERA, 1.42 WHIP and 11/9 K/BB ratio across 12 2/3 innings (three appearances, two starts). No word yet on how long the 22-year-old lefty will be sidelined, but he figures to miss at least a couple weeks, even in a best-case scenario.
