PHOENIX -- If this was indeed Patrick Corbin's final start at Chase Field in a D-backs uniform, it most certainly was not one he's going to want to remember.
The left-hander struggled with his command and lasted just three innings as the D-backs fell to the Rockies, 5-1, on Saturday night and slid closer to postseason elimination.
"Just a frustrating day," Corbin said.
Corbin (11-7) was acquired by the D-backs in a trade with the Angels in 2010 and made his Major League debut with Arizona the following year. A two-time All-Star, Corbin is a free agent at season's end and, as one of the top pitchers on the market, he figures to land a big deal somewhere.

While it's possible that could be with the D-backs, it seems he may have pitched his way out of their price range. If that's the case, the next time he pitches at Chase Field it will be in another uniform.
"I don't know," Corbin said when asked if the thought crossed his mind. "People brought it up that I've heard. But I think when the season is over I'll be able to look back at that a little bit more."
As far as the season being over, the D-backs postseason chances are now nearly done, thanks to their 5-15 record in September, which includes seven losses in their last eight games.
With the loss, the D-backs fell seven games behind the first-place Dodgers in the National League West, and they also dropped to seven behind the Cardinals in the race for the second NL Wild Card spot. With just seven games left to play, that means the best they could do is tie either team, and that doesn't take into account the Rockies being 5 1/2 games ahead of the D-backs in both races.

"Guys are battling. We had a week or so with some really hard losses, we battled, we were in the lead in most games, and it just didn't work out," Corbin said. "Guys are still coming, we weren't getting W's, we were out there fighting. It's just frustrating. We played some really good teams. We think we're just as good as those teams. It's frustrating knowing how good of a team we do have and it's unfortunate the situation we're in at this point in the season."
Corbin struggled with his command, allowing four walks to go along with five hits over three innings.
The Rockies broke things open against him in the third when they sent nine men to the plate and scored all four of their runs with two outs.
"I just think he was one click off," D-backs manager Torey Lovullo said. "Something was off."

After he was removed from the game, Corbin spent more time than usual in the dugout before going in to get treatment. He sat for a while near the end of the bench, alone with his thoughts.
"I just kind of sat there for a little bit," he said. "When you don't go deep in the ballgame, it's tough to just leave all the guys out there that are fighting still. I was hanging out for a little bit, frustrated with the way I played." 
SOUND SMART
The D-backs are 8-10 against the Rockies this season. It marks the first time since 2014 that the D-backs will finish a season with a losing record against Colorado.
HE SAID IT
"We're a good baseball team. We're a damn good baseball team and we haven't performed up to expectations, and that's probably most disappointing." -- Lovullo
UP NEXT
The D-backs wrap up the three-game series with the Rockies on Sunday at 1:10 p.m. MST at Chase Field with right-hander Zack Godley (14-10, 4.79 ERA) on the mound. Godley has lost each of his previous three starts. Last time out against the Astros, Godley allowed five runs (four earned) on seven hits over just 3 2/3 innings. The Rockies will counter with left-hander Kyle Freeland (15-7, 2.95 ERA).
