Colorado called up Ryan Ritter on Friday ahead of its series opener against the Mets, paving the way for the shortstop’s MLB debut. Ritter has been tearing up Triple-A, as he was named the Pacific Coast League Player of the Month on Thursday after slashing .381/.445/.918 with 10 doubles, 12 homers and 31 RBIs in May.

Ryan Ritter's hot streak at AAA earns him a starting opportunity with the Rockies after Ezequiel Tovar lands on the IL.

Ritter had his contract selected from Triple-A Albuquerque on Friday before Colorado began a three-game series with the NL East-leading New York Mets. Tovar was placed on the 10-day injured list — retroactive to Tuesday — with a strained left oblique.
