NL Notes: Cubs, Nationals, Strasburg, Heyward, Gosewisch, Giants

Earlier, we discussed a report from Gordon Wittenmyer of the Chicago Sun-Times indicating that the Cubs will be players if Ben Zobrist is marketed. In that piece, he also discusses the team’s need for pitching. Chicago is “in the mix” for Rafael Soriano and could also be interested in Diamondbacks lefty Oliver Perez. Discussing the team’s summer plans, president of baseball operations Theo Epstein hinted that the club will be looking hard at additions — as Patrick Mooney of CSN Chicago said he expected on last week’s MLBTR podcast. “We’re trying to balance short- and long-term interests,” said Epstein. “But we’re in a situation [in which] we have a fairly competitive team right now, and we have some needs. So you don’t ignore that. You keep it in mind. But at the same time you can’t just go out and unilaterally add.”

• Nationals GM Mike Rizzo indicated that he believes the club can get by with internal options like Michael Taylor and Tyler Moore while Jayson Werth recovers from a fractured wrist, as Chelsea Janes of the Washington Post reports. The left-handed-hitting Clint Robinson could also see time. My own guess is that another lefty bat could be acquired if the right player becomes available, but that the team will not be aggressive unless the need becomes more apparent. It’s worth recalling, too, that Matt den Dekker is still available at Triple-A, with Nate McLouth still a possible candidate to return later in the year.
• Stephen Strasburg left tonight’s start for the Nationals after just five batters. As Dan Kolko of MASNsports.com reports (Twitter links), Strasburg is said to have suffered a left trap muscle issue of some kind. The righty, who has struggled uncharacteristically, said that his neck tightened up so much that he had trouble turning his head. While it does not appear that there is any concern with arm issues, Strasburg’s general difficulties and neck and back issues are certainly an increasing problem for him and the club.
• Cardinals GM John Mozeliak says he does not have any retrospective qualms over his acquisition of outfielder Jason Heyward, Bernie Miklasz of the St. Louis Post-Dispatch writes. Heyward has shown some signs of life after a rough start, but the outstanding early performance of Shelby Miller stands in stark contrast at present. “I think whenever you make those kind of deals, there are reasons behind it,” Mozeliak explained. “And at the time, we felt that we had to do something. Not only looking at how we want this club to be put together, but we did not feel like there might be any other opportunities that would meet the type of criteria we’re looking for.” 
• Though he has not yet been evaluated, injured Diamondbacks catcher Tuffy Gosewisch says a radiologist that looked at the MRI on his knee believes he may have a torn ACL, Nick Piecoro of the Arizona Republic tweets. Certainly, that would mean a disappointing end to the year for the 31-year-old, who has struggled at the plate in his opportunity at a starting role. Arizona has called up recent signee Jarrod Saltalamacchia, who will presumably take a good portion of the time behind the dish.
• Several Giants players have upcoming opt-out dates, Andrew Baggarly of the Mercury News writes. Righty Kevin Correia can become a free agent on the first of June, while third baseman Casey McGehee can opt out on June 5.
