Eaton learns from successful mistake
By Steve Gilbert and Tyler Emerick / MLB.com
PHOENIX -- D-backs outfielder Adam Eaton ran through a stop sign from third-base coach Matt Williams on Thursday night, drawing some good-natured teasing, but also some serious advice.
Eaton led off the bottom of the first with a walk, and when Aaron Hill followed with a double to the left-field corner, Eaton came barreling around third base and ran right by Williams, who had his hands up, signaling him to hold up at third as the Cubs' relay throw came in.
Thankfully, for Eaton's sake, left fielder Cole Gillespie missed the cutoff man with his throw, and Eaton was safe.
D-backs manager Kirk Gibson was seen talking to Eaton in the dugout after the play.
"He's good to go all the time, but it wasn't a very smart play, we got away with one there," Gibson said. "Kid is just trying to do good. You don't want to criticize him for the effort, but at the same time he's got to be smart with that and pick up his coach early on."
The smart play in the first inning with no one out would have been to stop at third.
"It wasn't a good play on my part," Eaton said. "You need to stop there, especially first inning."
Eaton did not actually see Williams until he was literally running right past him.
"I was kind of reading it on my own, and literally the first time I saw him I had touched third and was rounding third," Eaton said. "I need to pick him up a little sooner. I'm glad it worked out, but definitely going forward I've got to pick him up sooner."
Hill likely out until Sunday with tight hamstring
PHOENIX -- D-backs second baseman Aaron Hill was removed from Friday night's 10-0 win over the Padres after two innings with right hamstring tightness.
Hill felt the hamstring stiffen up while scoring from second base in the first inning after he had doubled home a run. He notified the coaching staff but remained in the game. An inning later, Hill hit his second RBI double of the night to make the score 4-0, and D-backs manager Kirk Gibson said he saw the veteran "dragging his leg a little bit." Once the Padres retired the side, Gibson told Hill he was coming out.
Eric Chavez came off the bench to man third base, while Martin Prado shifted from third base to second.
"I could've finished the game, but I just took it easy," Hill said. "Not worth it today."
Although neither Hill nor Gibson seemed concerned about the injury, the skipper said after the game that the 31-year-old will be out of the lineup Saturday, a decision Hill plans to fight.
"That's debatable," he said. "I haven't got to argue my case yet."
If Gibson does win out and Hill doesn't play Saturday, he said he will most likely put him back in the lineup Sunday before the team has an off-day on Monday.
Cahill strikes out nine in first rehab start
PHOENIX -- D-backs right-hander Trevor Cahill made his first injury-rehab start on Thursday night in an Arizona League game at Salt River Fields.
Cahill, who was placed on the disabled list July 1 with a right hip contusion, allowed one unearned run on one hit while striking out nine and walking two in five innings against the Angels rookie team.
"I was just trying to get a feel for everything," Cahill said. "I threw a good mix of everything. Curveball was good, cutter was good -- fastball, I was throwing more four-seamers."
Though he went on the DL for the hip, Cahill experienced some shoulder soreness when he first began throwing a couple of weeks ago. That, though, was a one-day occurrence.
When he woke up Friday morning, he knew it had been a while since he had been on a mound.
"Definitely a little sore," he said. "But nothing unusual."
The team has not decided whether Cahill will pitch on the fifth or sixth day following Thursday's start and whether it will be for Triple-A Reno, though that seems likely.
Cahill was not sure if he would need one or two more rehab starts before being ready to be activated.
"It's tough to say," he said. "Yesterday I definitely felt like I was getting tired. So I want to get back to where I can throw 110 pitches and be normal tired coming out of the game."
Cahill has used the time on the DL to work on his mechanics a bit. While struggling to a 3-10 record and 4.66 ERA before the injury, Cahill has tried to be more consistent with his release point and to use his legs more during his delivery.
• Catcher Miguel Montero was out of the lineup for a fourth straight game Friday, but his sore back had improved to the point where he could swing a bat for the first time since experiencing the discomfort.
Montero will likely be back in the lineup Saturday.
"We got away with it so far," D-backs manager Kirk Gibson said of avoiding a DL stint. "Tonight he's not starting, but that doesn't mean he won't play. I think everyone feels much more confident with where's he's at and he feels much more comfortable with himself."
• Left-hander Wade Miley said his right leg was feeling better one day after he was hit by a sharp comebacker in his start against the Cubs.
Miley, who said he expects to make his next start without a problem, was reminded of the injury when his dog rolled over on it this morning.
"Wade was like a comedy show when he was getting treatment today in the training room," Gibson said. "It's like I told him he acts tough all the time so he had to be tough last night. He did a good job. That was no easy day in the park."
