Colorado Rockies manager Jim Tracy has decided to rest several of his regular starters and put in the backups for Sunday's finale against the Houston Astros. Tyler Colvin will start in center field for Dexter Fowler, Jordan Pacheco will be at the hot corner while Chris Nelson rest, Jason Giambi is relieving Todd Helton at first base, Wilin Rosario is behind the plate for Ramon Hernandez and Jonathan Herrera takes second base from Marco Scutaro.

The Rosario start is as expected, but Tracy continues to put out a Sunday lineup that rests most of his top players with the series on the line.

Astros manager Brad Mills, however, will put out his Opening Day lineup (minus the pitcher) for this rubber matchup.
