Rockies optioned RHP TJ Shook to Triple-A Albuquerque.
The 28-year-old hurler made three appearances during his brief stay with the Rockies, posting a 4.91 ERA, 1.09 WHIP and a 3/0 K/BB ratio while serving up a pair of homers in 3 2/3 innings of work. He was unlikely to be available on Sunday after throwing 33 pitches over 1 2/3 innings on Saturday though, so the Rockies decided to swap him out for a fresh arm. He should get another chance with the big league club before the summer is through.
