When the Diamondbacks traded Carlos Gonzalez, Brett Anderson, and others to the A’s for Dan Haren in 2007, the plan was for him to join Brandon Webb in the rotation and solidify the dynasty that many thought the Diamondbacks had started with their trip to the playoffs the previous season.
It started off well. He went 16-8 with a 3.33 ERA/138 ERA+ and earned himself a spot on the All Star team. He and Webb did exactly what they were supposed to do and shut down hitters in almost a third of the games that season. The overall results weren’t quite there, as the team record was just one game over .500, but the principle worked.
Then it didn’t. You all know what happened. Webb went out to start Opening Day 2009, and then was never seen in an MLB stadium again until he hosted the Dbacks pregame show.
Haren continued to the be ace we traded for after that. The W/L record was a little less nice, going 14-10, a 3.14 ERA and a 142 ERA+. That got him another trip to the All Star Game, and this time also a fifth place finish in the Cy Young Award voting. However, that was about all it was good for, as the rest of the team limped to a 70-92 record and a last place finish in the NL West.
The next season, 2010, was something of a nightmare for the Diamondbacks. No one on the team managed to pitch well, and the team decided to get something for Haren instead of leaving him on a team that clearly wasn’t going anywhere. He was shipped off to Anaheim for Joe Saunders, Patrick Corbin, Tyler Skaggs, and Rafael Rodriguez. I’d say that worked out well.
For a while, that looked like the end of Haren’s story with the Diamondbacks. He spent a couple years with the Angels, and then a few other teams. After the 2015 season, he retired. He did not however go quietly into the night. Fast forward to the start of the 2017 season, he joined the Dbacks once again this time as assistant pitching coach to Mike Butcher. At the time, several of us on here thought that he was one bad month away from replacing Butcher as the pitching coach, but that never materialized. As far as I can tell, though, he still holds that position.
