Trade Anyone Over 30 (Except Ziegler)

Brad Ziegler has done everything in his power to stay as the closer of the Dbacks. Not only has he succeeded, but he’s been the bullpen’s saving grace. In 41.2 innings, Ziegler’s 1.08 ERA is absolutely spectacular. Ziegler hasn’t surrendered a run in over 6 weeks, a span that has gone 16.2 innings.

Contenders have taken notice and undoubtedly inquired about Ziegler’s services. With Ziegler being a free agent at the end of the season, and with his age of 35, it makes conventional sense for the Dbacks to acquire something for him. However, this move will leave the bullpen in complete disarray, not to mention the fact that the Dbacks can find themselves back in the race.

As for Aaron Hill, the Dbacks can’t get rid of him soon enough. Hopefully. It’s only becoming more difficult as the days go on. Hill, 33, is having a pretty difficult season. Hill is hitting .220 with 4 homers and 23 RBI. Hill can’t be considered for a starting infielder position on a contender. However, Hill can be a platoon player against left handed pitcher and a pinch hitter off the bench.

Hill’s glory days of Toronto are long behind him. Hill’s best season with Arizona came back in 2012 when he smacked 26 homeruns, drove in 85 runs, and hit .302. Ever since, his hitting numbers have hit a sharp decline. What is more difficult is his lingering salary. Hill is owed another 12 million for the 2016 season.

Another name that could find a new home is Oliver Perez. Perez, 33, is having another productive season in 2015. Perez is 1-1 with a 3.46 ERA and 31 strikeouts in 26 innings. Since moving to the bullpen in 2012, Perez has kept his season ERA under 3.75. Perez, a free agent in the winter, can be useful to a contender as a left handed specialist. With the emergence of Andrew Chafin, Perez is completely expendable.
