A lot of debate lately on the Twins rotation and May's evolving role. "Solving" the game of musical chairs problem has led to a building pile of unanticipated consequences. Due to Tommy Milone's injury, an unproven rookie has now been called up to debut in an away game- in the midst of the most pivotal series for the Twins so far this year (ie, Tyler Duffey vs. the best-hitting team in baseball, the Toronto Blue Jays, on Wednesday). Meanwhile, Pelfrey has silenced the critics for now with a brilliant performance on Sunday vs. the Mariners. Here are some of the recent posts regarding the May situation: And the following is my reprint with the pertinent data, vis a vis May vs. Pelfrey. 1) Regarding Trevor May and the Twins explaining their intentions for him, starting on July 1 to August 2: I'm sure he's been talked to, but Molitor showed his hand early on when May was moved out of the rotation; when questioned by reporters, he said that keeping him in a limbo role- aka "The Plan"- with the Twins won out over sending him down and continuing to start him in the AAA rotation. May no doubt is a good soldier, but I have to think his head was spinning when he got his talking to. He led all starters in fWAR for the month of April, as well as for the months of May and June combined... and he was actually getting better from mid-May until his demotion after his start on July 1 (*** check the stats on his last 9 starts below). 2) If it really, truly, "isn't about May at all", maybe it should have been? 3) Milone was very effective for the month leading up to the ASG, but wouldn't it have been nice to have been able to plug May into his slot 2 starts sooner when Milone was obviously struggling, post ASG? And are we just to assume that Milone returns to his June form after his DL stint? 4) Here is a pretty comprehensive summary of the comparable data measuring each pitcher's recent effectiveness and (alleged) innings-eating capabilities: Before today's game, strictly SP comps: Pelfrey eats up innings Pelfrey- 5.8 IP/Start May- 5.4 IP/Start Pelfrey manages his pitch count Pelfrey- 91.2 Pitches/gm 63.4% Str% May- 86.4 Pitches/gm 66.2% Str% May is shining in the pen Yes, but in 10 relief appearances, he's pitched in 2 high lev situations and 0 medium lev. His velocity is up but his K/9 and K% are actually lower than when he was a starter. Pelfrey eats up innings Pt. 2 In his last 9 starts, counting Sunday's 8 IP effort, Pelfrey has gone 7 or 8 IP a grand total of THREE TIMES. In his last 9 starts, May went 7 IP a grand total of THREE TIMES (OK, one of those 3 was 6.2 IP) ***May is shining in the pen Pt 2 (but he was also shining in the rotation, and had improved quite a bit on his season's stats previous to that point in time [May 16- July 1]) In his last 9 starts, May averaged 5.6 IP. K/9 8.40 BB/9 1.79 ERA/FIP/xFIP 3.75/3.23/3.62 In his last 9 starts, Pelfrey avrgd. 5.7 IP. K/9 4.56 BB/9 2.98 ERA/FIP/xFIP 5.44/4.70/4.45 May throwing 97 out of the pen has value. Comp above to May's first 9 relief apprncs K/9 6.97 BB/9 1.74 ERA/FIP/xFIP 3.48/3.67/4.60 Conclusions: 1) When strictly comping the stats for the 2, Pelfrey was/is clearly the inferior choice to start, and he doesn't significantly eat more innings. 2) May's peripherals demonstrated that he has actually been less effective in a relief role than as a starter, and obviously, he hasn't been able to help the team in his current evolving role nearly as much as he did through July 1 in his previous role. 3) The Twins, instead of putting May into a limbo role, needed to bolster their bullpen, before the AS break- from outside the organization or from the minors, or both. They knew about the impending Santana situation crowding the rotation from Day One, they also knew that Boyer, Stauffer and Fien were poor options for the 7h-8th innings from just a few days after Day One.
