Left-handed pitcher Franklin Morales’ return to the Rockies rotation was cut short Tuesday.

Warming up to pitch in the third inning, Morales was stopped by catcher Yorvit Torrealba, who signaled for trainer Keith Dugger to come to the mound. After consulting with pitching coach Bob Apodaca, Morales was replaced by Glendon Rusch.

The Rockies announced that Morales suffered a strained left shoulder.

Morales left with a 3-2 lead. The Rockies scored twice in the top of the second, their first lead in 32 innings. After back-to-back home runs from Chris Young and Eric Byrnes leading off the bottom of the second tied the game at 2-2, the Rockies came up with another run in the top of the third.

Morales earned a victory in the third game of the season at Arizona, allowing one run on four hits in six innings. He was sent to the minor leagues after that game to get a start while he waited for Tuesday, which was the second time this season the Rockies needed a fifth starter.
