11:32pm: Hayes has already cleared outright waivers and been assigned to Triple-A, MLB.com’s Mark Sheldon tweets.
Hayes, 28, has struggled in his first taste of the majors this year. Over 9 2/3 innings, he’s allowed nine earned runs on 15 hits, including three long balls. Hayes has struck out eight while issuing six walks in that small sample. He did turn in a nice season last year, tossing 58 innings of 2.95 ERA ball at the Triple-A level with 8.7 K/9 against 4.7 BB/9.
As for Selsky, 26, this represents his first crack at the big leagues. He was carrying a .275/.380/.383 slash line in 142 plate appearances for Triple-A Louisville. Though he did show greater pop in the lower levels of the minors, Selsky seems to have settled in as more of an on-base threat than a source of power as he’s moved up the ranks.
