NL Notes: Stauffer, Phillies, Cubs, Hairston

Let's take a look around the National League …

• Pitcher Tim Stauffer was called up by the Padres, meaning that the team will not risk losing him to a June 1 opt-out clause, notes Bill Center of the San Diego Union-Tribune. Returning for the second time in his career from major arm surgery, Stauffer was thrown right into the fire and worked 1 2/3 effective innings last night against the Nationals.
• Phillies GM Ruben Amaro Jr. believes his club has the pieces in place to be much better offensively and is not looking for outside help at the moment, Jim Salisbury of CSNPhilly.com reports. "I don't see us making any trades any time soon," Amaro said. "There's too many teams that are in it, not enough teams that are out of it." Amaro is preaching patience with struggling hitters like Delmon Young and Ryan Howard: "Right now we have to be patient to see if Delmon starts swinging it. And Ryan [Howard] is going to have to start swinging it. If those guys do then we'll be OK. If they don't we'll have to figure out what we're going to do." As Salisbury notes, the Phillies rank near the bottom of baseball in most major offensive categories, including on-base percentage (.304, 25th); OPS (.683, 26th); and runs scored (3.61, 27th).
• Prospective free agent Matt Garza will make his season debut for the Cubs this Tuesday, tweets Bruce Miles of the Daily Herald. Garza, who last checked in at eighth on Tim Dierkes's 2014 Free Agent Power Rankings, will be an interesting player to watch over the coming weeks. Depending upon his performance and the intentions of the Cubs, he could be an extension candidate, prime mid-season trade bait, and/or a major 2014 free agent target. 
• To make room in the rotation for Garza, Miles further notes, the Cubs will bump Carlos Villanueva to the bullpen. The right-hander, who is in the first half of a two-year, $10MM deal with the Cubs, has struggled since a promising start to the 2013 campaign. After allowing just five earned runs and logging 29 1/3 innings in his first four starts, Villanueva has conceded eighteen earned runs and lasted only 23 1/3 innings over his next four outings. Pitching from the pen, Villanueva is much less likely to profile as a potential trade candidate for the Cubs.
• In spite of a nice 2012 season in which he slashed .263/.299/.504 and hit 20 home runs over 398 plate appearances for the Mets, outfielder Scott Hairston says that the team never formally offered him a contract this offseason. As Adam Rubin of ESPN.com reports, Hairston felt that New York "wanted to go in a different direction," leading him to look elsewhere for a multi-year deal and regular playing time. He ultimately landed a two-year deal with the Cubs that guarantees him $5MM. Now, both player and team seem to be regretting how things turned out: the Mets outfield has been terrible, and Hairston has struggled in limited action for Chicago with a .125/.154/.354 line over just 52 plate appearances.
