PEORIA, Ariz. -- Of the three pitchers competing for the No. 5 spot in the D-backs rotation, there's no question Patrick Corbin has pitched the best so far this spring.
But with more than two weeks left to go there is still time for Tyler Skaggs and Randall Delgado to make their cases.
Corbin allowed one run on four hits in four innings of work Tuesday against the Mariners in a 5-4 victory. Three of his four outings have been impressive.
"I'm certainly not disappointed, but I don't want him to get in a position where he's just happy with what he's done so far," D-backs manager Kirk Gibson said. "He's got to keep pushing to get better and better and better."
Corbin worked on throwing his two-seam fastball in to left-handed hitters and was pleased with his outing.
"I felt good today," he said. "I was able to locate my fastball and I thought I threw some real good changeups today. The three of us are all going out there fighting for [the No. 5 spot], but you have to go out there and just pitch your game and I feel that's what I've been doing."
For Eaton, it's easier to hit HRs than savor them
PEORIA, Ariz. -- When D-backs outfielder Adam Eaton homered Monday, he nearly passed pitcher Trevor Cahill, who was on base at the time.
It doesn't even seem right to call it a home run "trot" for Eaton, it's more like a sprint.
"The game takes long enough as it is and no one wants to watch me just trot around the bases," Eaton said. "They don't want to see that. Just hit your home run, get around the bases and let the next guy hit. It's nice to enjoy it, but at the same time, just act like you've done it and get around the bases."
Power is not a big part of Eaton's game. He has hit 24 home runs in 1,210 Minor League at-bats and he had two in 85 big league at-bats last year.
Eaton has sprinted around the bases throughout his pro career and has heard from teammates as well as his wife, Katie, that he should slow down and enjoy the moment.
"I'm sure if I hit it in the World Series I may slow down," he said with a laugh.
• Right-hander Daniel Hudson threw a flat-ground bullpen session Tuesday for the first time since last summer's Tommy John surgery.
"He's been doing great and there have been no setbacks," Gibson said. "For him, I'm sure it's significant in that it puts him a step closer."
Hudson is not scheduled to return until mid-July.
• The D-backs will cut their roster down in the coming days. The reduced numbers will help the club get more individual drill work in. Since the Minor Leaguers began Spring Training, the D-backs have been limited to two full fields and the numbers are too many.
• Eric Chavez was back in the lineup Tuesday against the Rockies after being hit in the forehead with a grounder Monday. Chavez was scratched from Monday's lineup. Meanwhile second baseman Aaron Hill was scratched from the lineup Tuesday. Hill left Monday's game early with a stomach virus.
