CHICAGO (AP) — The Colorado Rockies have sent down prospect Ryan McMahon and promoted infielder Daniel Castro from Triple-A Albuquerque.

McMahon is batting .180 with no homers and three RBIs in 28 games. The infielder also has struck out 22 times in 60 plate appearances.

The 25-year-old Castro had a 22-game hit streak with the Isotopes at the time of the move. He got the start at second baseman for Tuesday night's game against the Chicago Cubs in his first major league appearances since Sept. 30, 2016, for Atlanta against Detroit.

The Rockies also transferred left-hander Zac Rosscup to the 60-day disabled list with a left middle finger blister.
