The outcome: Smith bloops a two-run double down the left-field line to give the Rockies the lead.
The analysis: Morales had held the Diamondbacks to a run on five hits, but with two outs and two runners in scoring position, it was the right call to pull him with a chance to take the lead. And did Smith ever deliver.
"Down 0-2, I was just looking to get the barrel on the ball; when you make contact sometimes good things happen. It wasn't hit hard, but obviously I'll take it."
One on one
The Diamondbacks trailed, 6-4, with two outs and a runner at third in the eighth.
Hurdle replaces left-hander Brian Fuentes with right-hander Manny Corpas, and Arizona manager Doug Melvin counters by sending switch-hitting slugger Tony Clark to pinch-hit.
The outcome: Corpas fans Clark to end the threat.
The analysis: Clark represented the tying run and certainly has the power to hit it out, but Corpas has been outstanding, so it was more favorable than Fuentes vs. the right-handed-hitting Jeff Cirillo.
"Manny's been doing the job for us all along and he did it again tonight."
No bunt, no problem
Arizona's Micah Owings on first with no outs in the top of the third.
Chris Young and Stephen Drew swing away instead of sacrificing Owings into scoring position.
The outcome: Young lines out to shortstop Troy Tulowitzki and Drew flies out, but Conor Jackson picks up both with an RBI single after Eric Byrnes walks.
The analysis: The Diamondbacks entered the game 2-for-17 with runners in scoring position, but having scored only four runs in three games, giving up outs wasn't an attractive option, either.
"Stephen, that's an easy one. He's my only left-handed bat there in the inning. It's going to be a fastball. He has a chance to tie the game. If that's not the tying run, then I obviously don't let him swing, but right there you know you're going to get a fastball, you know you're going to get a pitch to drive."
