With just a week and a half remaining on what is pacing to be one of the five worst seasons in franchise history, and with eight of their last 11 games against playoff teams from this year or last year, it’s time for the Rockies to throw in the towel and commit 100 percent to seeing if these three prospects can deliver at the Major League level.

Alternatively, there are players that need to be shelved for the rest of the season – possibly longer.

Three Down: Boone Logan

MLB: Colorado Rockies at San Francisco Giants

Logan has not been the shutdown left-handed arm that the Rockies envisioned when they signed him prior to the 2014 season. He’s improved on his performance in year two in a Rockies uniform – 4.59 ERA in 56 games versus 6.84 ERA in 35 games – but Colorado badly needs a hard-throwing lefty as the counter-punch to Christian Friedrich. Colorado hoped Tyler Matzek could have been that guy, but that obviously didn’t play out. Friedrich himself hasn’t done much to warrant a long-term future with the club, but he’s got far more tread left on the tires than Logan. Colorado should shelve Logan, who still has a year left on his contract, and save him some late season wear and tear since he’ll almost definitely be back in 2016, despite his $6.25 million price tag.
