HOUSTON -- Aaron Hill got the idea from Frank Thomas.
What Hill learned from Thomas is that when serving as designated hitter, as he did on Thursday night against the Astros, it's a good idea to sweat.
"Frank Thomas would always ride the bike just to stay loose," Hill said. "That kind of gave me the idea -- not necessarily to do the same thing, but at least keep a sweat going and stay loose to get ready for the next at-bat."
Hill has served as DH before. After all, he spent seven seasons playing for the Blue Jays in the American League. He said it's important to watch how an opposing pitcher is throwing, but mostly, he'll make sure he's staying loose.
"I'll probably be in the weight room, running around, just breaking a sweat," he said.
Hill was one of the only members of the D-backs to have success against Dallas Keuchel in Wednesday's 5-1 loss to the Astros.
In the fourth inning, Keuchel threw a fastball inside that Hill turned on and sent to Minute Maid Park's Crawford Boxes for the D-backs' only run.
Hill will try to keep that success going against Houston's Scott Feldman on Thursday as the D-backs look to split the series.
D-backs pick up infielder Pacheco, designate Evans
HOUSTON -- The D-backs announced the addition of Jordan Pacheco to the club on Thursday after claiming the infielder/catcher from the Rockies and designating utilityman Nick Evans for assignment.
Pacheco joined the team as it faced Houston on Thursday night at Minute Maid Park.
"You don't want to be a distraction," Pacheco said. "You just want to blend in. I did the best I could."
In addition to third base, second base and catcher, Pacheco can play the outfield -- versatility that helps him stand out -- though the team hasn't specified if he'll be slotted into a more specific role. For now he's ready to help at any position.
"When I get a bunch of reps at a certain position, obviously I get more comfortable in that atmosphere and that setting," he said. "The last few years, it's kind of been just going out there, whatever position I'm at, [to] just compete.
"I'm definitely happy to be here," he said. "I've played against a bunch of these guys, and I'm glad I don't have to face some of these pitchers anymore."
Evans had just one hit in 11 plate appearances for the D-backs this season, including an 0-for-3 performance against the Astros on Wednesday night as the designated hitter.
In 72 at-bats for the Rockies this season, Pacheco hit .236, with eight RBIs and six doubles.
Although he has struggled at the plate in 2014, he's a career .281 hitter, including .309 in 2012.
"He's a really good hitter," manager Kirk Gibson said. "He's a good fit for us right now."
Inciarte exits as precaution after collision
HOUSTON -- A collision on a stolen-base attempt led to Ender Inciarte's early exit from Thursday's game against Houston.
In the third inning, as Inciarte attemped to swipe second base, Houston's Jonathan Villar left the ground to field the throw from catcher Carlos Corporan, and his leg made contact with Inciarte's head.
Inciarte remained in the game and struck out swinging on his next at-bat, in the fifth inning, before being removed.
"He just wasn't feeling good, so we got him out of there," manager Kirk Gibson said of Inciarte, who is batting .205. "We'll be cautious on that situation."
Arizona signs four more Draft picks
HOUSTON -- The D-backs on Thursday announced that they have agreed to terms with four more picks from the 2014 First-Year Player Draft.
One of the four, Matt Railey (third round, No. 89), actually came to an agreement with Arizona on June 7 and had been assigned to short-season Missoula.
Kevin Simmons (16th round), Mike Abreu Jr. (17th) and Tyler Bolton (33rd) have agreed to contracts as well; all have been assigned to Missoula.
On Wednesday the D-backs announced agreements with 15 Draft picks, including Isan Diaz, who they selected with pick No. 70. Diaz signed for $750,000, below the slotted pick value of $804,600.
The D-backs have agreed to terms with 19 of their 42 picks.
