Duffey began the 2014 season with four starts in Ft. Myers. He moved up to Double-A and then ended his season with three starts in Triple-A Rochester. He earned an invitation to big league camp, but then he began this season back in Double-A, this time with Chattanooga. He had to be disappointed, but he handled it well. He made eight starts and went 2-2 with a 2.56 ERA in 52.2 innings.
He earned a promotion back to Triple-A Rochester. In his first four starts for the Red Wings, he went 0-4 with a 5.64 ERA and a 1.34 WHIP in just 22.1 innings. Opponents hit .312/.340/.387 (.727) against him.
However, he has made some adjustment and in his seven starts since then he is 4-1 with a 0.74 ERA and a 0.64 WHIP over 48.1 innings. Opponents have hit just .174/.230/.236 (.466).
While with Chattanooga, he had a streak of 16.2 innings without allowing a run. With the Red Wings, he had a streak of 33.2 innings without allowing an earned run.
In most recent Twins seasons, Duffey would likely already be making starts in Minnesota. However, the Twins starting rotation has been strong this season. Even if the Twins were to remove a starter from their current rotation, Trevor May would be the guy who would jump back into the starting rotation.
No offense to Taylor Rogers or JO Berrios (who had another strong start on Thursday), but if the Twins needed a starter from Rochester, Duffey would have to be the choice.
That brings us back to the Twins struggling bullpen. Is it time for the Twins to give Tyler Duffey an opportunity in their bullpen?
Duffey has been primarily a starter in the Twins minor league system. You recall, however, that the Twins drafted Duffey in the fifth round of the 2012 draft. At Rice University, he was a reliever. He was a co-closer with JT Chargois (current closer in Chattanooga). In other words, the bullpen role would not be unfamiliar to him.
If the Twins were to call up Duffey in the next couple of weeks to pitch out of their bullpen, it wouldn’t have to mean that he would need to remain a reliever. Depending on the Twins offseason, he could be moved back to the starting role in the 2016 season if that makes sense. It would be a move to help them in their hopes to make the playoffs in 2015.
That isn’t to say that you call him up and immediately throw him into the eighth inning. The goal would simply be for him to help bridge the gap from starter to Perkins. There are games when they need a guy to finish the sixth or pitch a couple of innings. Duffey can do that.
His transition to starter happened in the Twins minor leagues in 2013, his first full pro season. As he told Twins Daily in a spring training interview, “Except for a summer when I went to the Cape and somebody got sick and I made a couple of starts, but other than that, I was a closer/second-inning panic guy to come in and throw four innings.”
His stuff is ready for the big leagues as a starter. As a starter, he works with a fastball in the low-90s. His best pitch is his 12-6 curveball. He also has a decent change-up. In his limited time in pro ball when he has worked out of the bullpen, his fastball has touched 97. He said that one of the keys to his success has been his sinker. He is a ground ball pitcher.
Duffey is not currently on the Twins 40-man roster. He would need to be added, though I’m sure the Twins could find someone to remove from the roster if a move were needed.
There are relievers in Rochester who have pitched well in AAA and deserve an opportunity as well. Michael Tonkin has been back and forth between the Red Wings and Twins for the last three years. At some point, they just have to give him an opportunity and stick with him for an extended period of time. He is out of options in 2016.
If there is a most-deserving reliever in Rochester, it has to be AJ Achter. The former 46th round draft pick has been consistently terrific since being moved to the bullpen before the 2012 season. He debuted last September with the Twins. With the Red Wings this year, he is 4-2 with a Twins minor league-leading 14 saves. He has a 2.81 ERA and a 0.89 WHIP in 41.2 innings for the Red Wings. He’s walked just 2.6 per nine innings while striking out 9.3 per nine innings.
Starter Taylor Rogers, a southpaw, has limited left-handed AAA hitters to just a .189/.206/.197 (.403) line this year. With Brian Duensing improved of late and Ryan O’Rourke doing very well in his two weeks with the Twins, particularly against lefties, Rogers should continue to start for Rochester. However, he should also be a strong consideration for September recall.
JO Berrios is certainly the top prospect in Rochester. The 21-year-old dropped his AAA ERA from 5.60 to 4.01 with seven shutout innings on Thursday. He has very good stuff and will likely be considered for a promotion in August as well. He doesn’t need to be added to the Twins 40-man roster until after the 2016 season, but if the Twins believe he can help them win in 2015, they won’t hesitate to promote him.
AJ Achter should already be in the Twins bullpen. Tyler Duffey should be strongly considered as a bullpen arm down the stretch for the Minnesota Twins.
If you’ve endured the past four seasons as a Twins fan, this dilemma – plenty of deserving candidates for promotion to the Twins – is more than welcomed!
