The career of Zach Duke was an interesting trek, one that started in his debut 2005 campaign and ran to 2019 (yes, astonishingly, he was still pitching).
He gave Pirates fans hope with his stupendous rookie campaign, going 8-2 with a 1.81 ERA in 14 starts; he finished 5th in Rookie of the Year voting, despite his truncated season. Those hopes were dashed by the next year, however, as he lost 15 games and led the league in hits allowed, then went 3-8 and 5-14 the next two campaigns, respectively.
In 2009, he made the All-Star team, despite going 11-16, leading the league in losses and allowing 231 hits in 213 innings. In fact, he did not post a winning record from 2006 to 2011, breaking that run with a 1-0, 8 appearance campaign with Washington in 2012.
But that brief stint with Washington, in which he had a 1.32 ERA, was a hint of things to come. From that point to 2016, he posted a 3.12 ERA, a 126 ERA+ and a 9.4 K/9 IP ratio in 260 games as an effective left-handed relief pitcher for five teams. That ERA is deceptively high, too—it would be lower if not for a clunker campaign (2012, 6.03 ERA) thrown in. The veteran with nine big league teams under his belt might have pitched his last pitch, as he is currently a free agent.
