PHOENIX -- The D-backs will be represented by seven players on the Salt River Rafters of the Arizona Fall League this year.

The Rafters, who will be managed by Arizona third-base coach Matt Williams, will play their home games at the D-backs' Salt River Fields Spring Training home.

Pitchers Chase Anderson, Evan Marshall, Kevin Munson and Eric Smith will be joined by infielders Tyler Bortnick, Matt Davidson and Chris Owings.

This will be the Arizona Fall League's 20th season. The first game for the Rafters will be Oct. 9 at 6:35 p.m. MST at Salt River Fields.

Kennedy scoffs at possibility of being shut down

PHOENIX -- It has been a frustrating season for Ian Kennedy.

Every time the right-hander appears poised to go on a consistent run of good outings, he seems to hit a speed bump.

That, along with Kennedy's workload the past couple of seasons, has led some to speculate that maybe the D-backs should consider shutting him down before the end of the season. The club could then give his starts to one of its young starters, like right-hander Trevor Bauer, who's currently in Triple-A Reno.

Kennedy wants no part of that.

"Is that a joke?" Kennedy said when asked about the possibility. "If that was the case, I feel like there are a lot of guys that could just mail it in -- you know, just say, 'I don't have it this year, I'll see you guys next year.' That wouldn't work. Part of our job is we have to go out there even when we fail."

Kennedy's velocity has been down at times this year, but he insists that there is nothing physically wrong.

"Honestly, it's crazy and it's frustrating, but my arm feels really good," Kennedy said. "That's what drives me nuts. I feel really good and I'm not having success. It's just part of this game. It's a humbling game."

Last year, it seemed Kennedy could do no wrong, as he went 21-4 with a 2.88 ERA and finished fourth in the National League Cy Young Award voting.

Through 26 starts this year, Kennedy is 11-11 with a 4.44 ERA. He pointed to Dodgers ace Clayton Kershaw and the Giants' Matt Cain as two pitchers who have been able to sustain success year in and year out, something that he is striving to do.

"I mean there's only a handful of those guys," Kennedy said. "I would like to be at that point. I showed to myself last year that I can do it, but this game is humbling. But it's not easy. You've got to constantly grind through the season. I always knew that, but you get spoiled by what happened last year."

Collmenter expected to rejoin D-backs on Saturday

PHOENIX -- Josh Collmenter threw four innings and 57 pitches in an Arizona Rookie League game on Tuesday, and the right-hander is expected to rejoin the D-backs on Saturday when rosters expand.

"I feel good, no limitations, no effects of anything," Collmenter said.

Collmenter was placed on the disabled list Aug. 10 after being hospitalized with stomach ulcers.

"Other than the few days I was in the hospital with it, there was no pain, no serious aftereffects," Collmenter said. "It took a few days to get my energy level back to normal, but that was it."

The last couple of weeks, Collmenter has been throwing at the team's Salt River Fields complex.

"It was weird being on the DL, but not having to rehab anything," Collmenter said. "Everyone else there was working on something, and I was just throwing."

Collmenter will have further tests performed on his stomach following the season.
