NL Notes: Ethier, Mattingly, Wacha, Pagan

Memorial Day weekend is the time when fans begin to zero in on what's happening in baseball, so Joel Sherman of the New York Post provides his analysis of the 2013 season. Sherman sees Cliff Lee, Matt Garza, Jose Bautista, Alex Rios, and Justin Morneau as the top five trade possibilities. Shin-Soo Choo was Sherman's choice as the best acquisition of 2013 with the combination of Justin Upton and Chris Johnson, Vernon Wells, Nick Swisher, and Mark Melancon rounding out the top five. Sherman also identifies the season's top storylines, prospects, and injuries to date. Let's focus on the news and notes coming from the National League:

• ESPN.com's Buster Olney writes the Mets make the most sense of the possible trade suitors for Andre Ethier (subscription required). According to Olney, the Dodgers will only deal Ethier if they decide he can no longer be an effective player for them and are willing to absorb a large portion of the approximately $80MM due the outfielder over the next five years. 
• Don Mattingly has all the hallmarks of a manager in quicksand and is conjuring up images of Clint Hurdle during his final days as manager of the Rockies, opines Troy E. Renck of the Denver Post. Hurdle vowed to exercise more authority by creating new rules and benched Troy Tulowitzki for violating one of those rules. Hurdle was fired one week later. Mattingly benched Matt Kemp for today's game calling it a "baseball decision" and not a disciplinary reaction to Kemp expressing his displeasure at being removed in a double-switch the night before, reports Bill Shaikin of the Los Angeles Times.  
• The Cardinals are looking to replace yet another starter and top pitching prospect Michael Wacha could get the call, according to MLB.com's Jenifer Langosch. Wacha is scheduled to start for Triple-A Memphis tomorrow afternoon, the same day GM John Mozeliak will meet with manager Mike Matheny and the coaching staff to determine who will fill the vacancy in the rotation. Nearly 40% of MLBTR's readers, when asked by Steve Adams this past Wednesday, predicted Wacha will be the next 2012 first-rounder to reach the Majors.
• Angel Pagan gave the Giants a dramatic victory last night with a walk-off inside-the-park home run. Adam Rubin of ESPNNewYork.com tweets the Mets made two mistakes in their December 2011 trade of Pagan to the Giants for Andres Torres and Ramon Ramirez: an inclination to non-tender a valuable player and, rather than non-tender, using that money on Torres and Ramirez.
