So as we look to the future and hope the younger Relief Pitchers start replacing some of the older MLB guys, who comes up first? Here are some contenders: Nick Burdi is a favorite among many here on TD but he is still at AA, has never been higher than AA, and has only pitched 16.2 innings in the past 2 years combined due to injuries. In 13.2 innings this year Burdi has struck out 18 while walking 4 and allowing only 1 run for a 0.66 ERA. His 0.67 WHIP is also impressive. Burdi has a career 1.24 WHIP in the minors. Mason Melotakis is also still at AA and also has never pitched any higher than AA after missing 2015 due to injury. Melotakis is repeating AA after 33 innings with a 2.97 ERA and 1.44 ERA there last year. In his second season in Chattanooga, Melotakis has pitched 15 innings with 11 K's compared to 3 walks. His WHIP is an impressive 0.60 with a career WHIP of 1.29. Melotakis has allowed two runs this year but one of those was unearned so his 0.60 ERA is even lower than Burdi. Trevor Hildenberger is in his first year in AAA with 10.2 innings logged this year. Hildenberger has struck out 12 while only walking 3. He has allowed 3 runs for a 2.53 ERA. In his favor is a terrific career 0.85 WHIP that is hurt by his career high 1.22 WHIP so far this year. Alan Busenitz spent most of last year in AA but, unlike the three above, he pitched 20.2 innings in AAA last year so comes with more experience. He has pitched in 12.1 innings this year with 15 strikeouts offsetting the 4 runs and 7 walks. His 2.92 ERA is solid and a 0.89 WHIP is really nice but his AAA career ERA is still 4.91 because of his AAA time BEFORE coming to the Twins in a trade midseason. DJ Baxendale has also been mentioned on TD as someone to bring up instead of some of the free agent signings we have seen. This year he has an identical ERA to Busenitz (2.92) in the exact same number of innings (12.1) but he is repeating AAA with the most AAA experience of anyone on this list. Last year, in 35 innings, he had a 1.29 ERA with 40 K's to 8 walks for a 1.03 WHIP. His K rate is down this year with only 9 so far but the control is there with only 2 walks and a 0.89 WHIP So, based on these numbers (and any others you would like to share with us in your responses), who do you think should be the first minor leaguer called up? Maybe it is someone not on this list...
