NL Notes: Reds, Mets, Diamondbacks

Outfielder Ryan Ludwick injured his right shoulder in the Reds' season opener and will need surgery. The Reds could promote Derrick Robinson or Denis Phipps to take Ludwick's place on the roster, Jon Fay of Cincinnati.com writes. Chris Heisey will take the bulk of Ludwick's playing time in left, so that makes an option like prospect Donald Lutz somewhat unlikely, since the Reds might prefer that he play every day. The Reds appear to have enough depth to avoid pursuing an option from outside the organization. Ludwick re-signed with the Reds for two years and $15MM in December. Here are more notes from around the National League.

• Pitcher Shaun Marcum is on the disabled list with biceps tendinitis, and the Mets will need to add another starting pitcher, ESPNNewYork.com's Adam Rubin contends (on Twitter). Chris Young, who pitched 115 innings for the Mets in 2012, is a free agent after being released by the Nationals, but the Mets did not appear interested (Twitter link) in Young several days ago, and as yet there have been no indications that Marcum's injury changes their stance.
• Diamondbacks GM Kevin Towers guarantees his team will win at least 90 games, Dan Bickley of AZCentral.com reports. "In 2011, I put down 85 and we won 94. Last year, I had 89 (wins) and we won 81," Towers says. "But I’ve been thinking about it. I’ve got a pretty good idea. I guarantee it’s going to start with a nine." The Diamondbacks are coming off an offseason filled with what Bickley calls "debatable, combustible maneuvers," including the trades of Justin Upton and Trevor Bauer.
