"I think this is a blip," Bridich said. "I don't think he's fallen off a cliff. We certainly still believe in him to the utmost degree and he'll be an impactful Major League pitcher for us again, like he was last year."
Last year, Matzek -- the team's top pick in 2009 -- made his debut and went 6-11 with a 4.05 ERA. He went 4-2 with a 1.55 ERA in his final six starts. He started this year 2-1 with a 4.09 ERA in five starts, but 19 walks in 22 innings and command issues earned him a demotion to Triple-A Albuquerque.
The Rockies removed him from game competition when he walked seven in one inning in his first Albuquerque appearance. After working on mechanics in Albuquerque and at extended spring training, he made three starts at Short-Season Class A Boise. In the third, on Aug. 24, he walked five and hit a batter while managing just one out. It was then he was sent home to rest for a restart.
• Rockies shortstop Jose Reyes received a warm applause before singling off Mets starter Jon Niese in his first at-bat on Monday -- although the Citi Field crowd liked his being picked off by Niese a little more. Reyes played for the Mets from 2003-11.
In a press gathering with mostly New York-area reporters, Reyes said he was disappointed when the Blue Jays -- fighting for a playoff spot -- traded him to a team that wasn't (for shortstop Troy Tulowitzki and reliever LaTroy Hawkins), but he sees enough positives to think the Rockies can compete as early as next season. The Rockies are coming off winning two out of three from the Nationals, who are just behind the first-place Mets in the National League East.
"They can play," said Reyes, under contract for two more seasons. "You see our lineup and these guys can hit. Hopefully the last two months of the season, we play better baseball and carry it over to next season.
"I feel for us when we play those kinds of teams they're like playoff games for us. We have to show them what we're made of."
• Righty Chad Bettis (5-4, 4.88 ERA), who hasn't pitched since July 18 because of right elbow inflammation, will throw a simulated game Tuesday at Citi Field. If all goes well, he'll leave for a Minor League rehab assignment afterward.
