NL Notes: D’Backs, Rockies, Cashner, Gonzalez, Davis

The news of the day was out of Arizona, where the Diamondbacks made a bold move to add Hall of Fame manager Tony LaRussa atop the club’s baseball operations department. Many observers hailed the move, with Jon Morosi of FOX Sports writing that the experienced and respected LaRussa could effect a “cultural overhaul” akin to that delivered to the Orioles by Buck Showalter. Of course, LaRussa’s role will be much broader than that of Showalter, and he’ll face quite a different challenge from the one that brought him to Cooperstown.

Here’s more from the D’Backs and the rest of the National League:

• The immediate reaction to LaRussa’s hiring was that embattled Diamondbacks GM Kevin Towers and/or manager Kirk Gibson could be on their way out. After reporting that a further shake-up would likely not occur in the immediate future, Bob Nightengale of USA Today provided some details on the previously unknown terms of the extensions given to both of those team leaders before the start of what has turned into a trying season (via Twitter). Towers’s deal takes him through 2016, while Gibson’s contract is believed to run through 2015, says Nightengale. Of course, that does not mean that the pair is ensured to last until those pacts expire.
• If the Rockies decide to shop for pitching, the club will have plenty of teams banging on the door for a chance to add one of their top two prospect arms (Jon Gray and Eddie Butler), reports Ken Rosenthal of FOX Sports (video link). But Rosenthal says that the team is more likely to bring one or both of those power righties up, noting that the team seems to have solid rotation depth.
• Padres staff ace Andrew Cashner was placed on the 15-day DL today after experiencing discomfort and inflammation in his right elbow. As Dennis Lin of the San Diego Union-Tribune reports, the 27-year-old says he is “not worried about my ligament at all.” Nevertheless, he will undergo a precautionary MRI on Monday. After a solid 175-inning, 3.09 ERA campaign last year, Cashner has elevated his game this year with a 2.35 ERA through 57 1/3 frames (7.4 K/9 against 2.7 BB/9). He is earning a $2.4MM salary for 2014, his first arb-eligible campaign, and should be in line for a big raise if he can stay on the mound and keep producing at those levels.
• Meanwhile, Nationals southpaw Gio Gonzalez suffered through a second-straight rough outing today, and manager Matt Williams said after the game that the club has been monitoring complaints of shoulder stiffness. As Adam Kilgore of the Washington Post reports, Gonzalez will undergo precautionary testing tomorrow, including an MRI. When asked if he was experiencing any health issues, Gonzalez gave a response that seems open to interpretation. “Realistically, arm was dropping a lot,” he said. “I guess we’ll see.”
• First baseman Ike Davis has regained his form at the plate since being traded to the Pirates, Jorge Arangure writes for the New York Times. Davis has compiled a .286/.383/.414 line through his first 81 plate appearances in Pittsburgh. In part, it bears noting, Davis has benefited from platoon usage: on the year, he has yet to record a hit in 15 plate appearances against same-handed pitchers, while sporting a nifty .902 OPS against righties. After several up-and-down years with the Mets, Davis said he is keeping his focus on the present and does not bear any ill-will to his former club.
