GM Notes: Future Candidates, Zduriencik

ESPN's Jim Bowden, a former GM of both the Reds and Expos/Nationals, recently took a look at Frank Wren's rise to general manager of the Braves. Within his ESPN Insider piece, Bowden identifies three front office executives who, like Wren, are being groomed as successors to their current GMs. He also identifies three candidates who will likely become GMs in other organizations. Here are some highlights from the piece and other GM news…

• Bowden feels that Rockies senior VP Bill Geivett, Tigers VP/assistant GM Al Avila and Athletics assistant GM David Forst are all next in line to become the GM of their respective franchises. Geivett, in particular, is already handling the day-to-day operations, and Bowden feels it's just a matter of time before he's given the official title of general manager.
• Bowden asked present GMs around the game who the top GM candidates outside of their own organizations were. The results, in order, were Rangers assistant GM Thad Levine, Cubs VP of scouting and player development Jason McLeod and Marlins assistant GM Dan Jennings. Bowden notes that each is blocked for one reason or another but would have plenty of interest from other clubs seeking a new GM.
• Jack Zduriencik's time as GM of the Mariners may be running out, writes Ken Rosenthal of FOX Sports. The Mariners once again find themselves last in the American League in runs scored — the same place they've been for the previous four years under Zduriencik's watch. Justin Smoak, Dustin Ackley and Jesus Montero have yet to establish themselves as big leaguers, and the trades of Cliff Lee and Doug Fister look poor in hindsight. Rosenthal notes that Hisashi Iwakuma is a coup for Zduriencik, and that help is close with Mike Zunino, Nick Franklin, James Paxton and Danny Hultzen at Triple-A. A breakthrough is needed soon, however, and Zduriencik conceded that he knows it.
