NL Notes: Dodgers, Brewers, Morales, Zimmerman, Welker

Tyler Stubblefield was stuck at low-A ball last year for the Padres at age 25. This year, writes MLB.com’s Corey Brock, he played a key role in recommending the team’s first-round draft choice, N.C. State shortstop Trea Turner, as San Diego’s area scout for eastern George and North and South Carolina.

Here’s the latest from the National League:

• It is time for the Dodgers to initiate a shake-up, opines Buster Olney of ESPN.com (Insider link). While the team undeniably has talented pieces, they have not fit together well, says Olney, who recommends that the team consider bringing up top prospect Joc Pederson to play center and installing the defense-first Erisbel Arruebarrena at short. Of course, those moves would have repercussions involving key veterans Matt Kemp and Hanley Ramirez, among others, but Olney says that dramatic action may be necessary with the club still sitting well back of the Giants in the NL West.
• The Brewers do not seem like a good fit for Kendrys Morales, MLB.com’s Adam McCalvy writes on Twitter. McCalvy says that two key questions — Morales’s ability to handle first and the team’s ability to fit him in the payroll — make a signing unlikely.
• Ryan Zimmerman says that he is not sure that he will ever return full-time to third base for the Nationals, as Adam Kilgore of the Washington Post reports. “I don’t know if I’m the best option over there anymore,” he said. “I’ve always said I’ll play until someone is better than me, or I’m not the best option at that position.” It will be fascinating to see how the Nats proceed when Bryce Harper returns, which is expected to occur around the turn of the month. While the team would have several options heading into 2015 — Zimmerman could stay in left and the team could deal Denard Span, or he could move to first if Adam LaRoche leaves town — the mid-season calculus is even more complicated. It seems hard to imagine that the team would leave second base in the hands of Danny Espinosa while taking away significant at-bats from any of the other players just mentioned. It seems at least possible that the Nationals could explore some creative trade possibilities to right-size the everyday lineup.
• Pirates righty Duke Welker underwent Tommy John surgery yesterday, reports Tom Singer of MLB.com (via Twitter). The towering 28-year-old was the player to be named later in last year’s Justin Morneau deal, but later returned to Pittsburgh in exchange for lefty Kris Johnson.
