D-backs point to pitch execution as Cahill's issue
By Steve Gilbert / MLB.com
SAN FRANCISCO -- D-backs starter Trevor Cahill's struggles come down to a simple matter of location.
"It's just hitter to hitter," D-backs GM Kevin Towers said. "He has a good sequence at times and then just kind of makes a mistake. If you talk to our trainers, he works harder than anybody, very well liked. I think he knows what he needs to do; he's just having a hard time executing the pitches right now."
In his first three starts this year, Cahill had a 7.90 ERA and had walked eight while striking out nine in 13 2/3 innings.
What causes people in baseball to shake their heads is how Cahill can have numbers like that given how good his stuff is.
"The stuff is still there where I think this guy can be a very successful big league pitcher," Towers said. "He just needs to be able to string together a couple of good starts to get his confidence back. His stuff is good, just location is not good right now. When you have poor location at this level, then you have bad results."
Like former D-backs starter Brandon Webb, Cahill has the kind of sinker that can be a dominating pitch.
"Getting to the point where he can execute pitches, that's going to be key for him and understanding really who he is," Towers said. "He's a power sinkerball pitcher. He's got a good changeup and a good curveball, but his bread-and-butter pitch is the fastball that's moving hopefully within the strike zone."
Gregorius off to hot start at Triple-A Reno
SAN FRANCISCO -- D-backs infielder Didi Gregorius has had a lot of success at the plate for Triple-A Reno so far this year.
Through eight games Gregorius was hitting .333 with three doubles, a triple and a homer.
Gregorius was one of the final cuts of the spring after losing out to Chris Owings for the starting shortstop job.
"I'm sure he took the demotion pretty tough, but went down there in the right frame of mind, positive attitude, and he's an injury away from being back up here and hopefully contributing," D-backs GM Kevin Towers said. "So we're happy with what he's done."
Gregorius has been alternating between second base and shortstop along with Nick Ahmed.
• D-backs GM Kevin Towers said that the team has not been looking to acquire a starter though trade, but they are looking for some depth at Triple-A Reno.
"There's a veteran [starter] that we've had some discussions with that we might sign to a Minor League deal in the next day or so," Towers said. "Just to give us more experience down there, we're pretty young and inexperienced in the rotation at Triple-A. But no, not looking at any trades."
• Outfielder Cody Ross was expected back in the Reno lineup Thursday after missing the past two games.
"He's taken a couple of days off," Towers said. "He had a little side issue, nothing major just something in his side that was bothering him a little bit so we gave him an extra day."
Ross will be with Reno likely through the weekend and then the D-backs will evaluate whether he's ready to be activated off the 15-day disabled list.
• D-backs outfielder Gerardo Parra finished a double shy of hitting for the cycle Wednesday night.
"What I liked a lot about last night was that he pulled the ball," manager Kirk Gibson said. "He turned on some pitches last night. Many hitters try to stay on the ball so much that they're always thinking about going the other way. If they get a ball middle third and they're staying back the way G was last night, you're able to turn on the ball and put some backspin on it. He got the triple and the home run and did that to two balls. It was a good trend. I like to see it."
