Much has been made of pitching in baseball over the past few seasons. The game has seen a shift from more dominant power-hitters to more shutdown pitchers since the “steroid era” “ended.”

While there are still many bona fide power hitters in the majors (Miguel Cabrera, Jose Bautista, Matt Kemp, Ryan Braun, Robinson Cano, etc.), building a strong pitching rotation has become more of a prominent priority for successful teams. Just last season (2011), baseball had a pitcher, Justin Verlander, win both the MVP award and the CY Young award in the American League. Pitching has always been important to America’s pastime but now it’s more crucial than ever.

Here is my second installment, breaking down each team’s potential starting rotation for the 2013 season with the average Earned Run Average (we know averaging an average isn’t scientifically sound, but we’re doing it anyway…): This time, the spotlight is on the AL Central…

Detroit Tigers:

1. Justin Verlander (17-8, 2.64 ERA, 239 Strikeouts)
2. Doug Fister (10-10, 3.45 ERA, 137 Strikeouts)
3. Max Scherzer (16-7, 3.74 ERA, 231 Strikeouts)
4. Anibal Sanchez (9-13, 3.86 ERA, 167 Strikeouts)
5. Rick Porcello (10-12, 4.59 ERA, 107 Strikeouts)

Average Combined 2012 ERA: 3.65

Chicago White Sox:

1. Chris Sale (17-8, 3.05 ERA, 192 Strikeouts)

4. Gavin Floyd (12-11, 4.29 ERA, 144 Strikeouts)
5. Jose Quintana (6-6, 3.76 ERA, 81 Strikeouts)

The addition of James Shields and Ervin Santana will boost that starting rotation to one of the stronger rotations in the division. I think Santana will overcome his shortcomings over the few previous seasons with the Angels and will return to form. I also believe Shields will now embrace his role of being the number one starter, coming out of David Price’s shadows in Tampa Bay.

Both the Twins’ and Indians’ rotations will be amongst the worst in the majors. Thin rotations are a big reason why it doesn’t look like either team will be competing for the playoffs again this season. While the Royals are the team I believe will end up with the most improved rotation, I still think the division title belongs to the Tigers. The division will come down to the last few weeks as it did last season, with the Tigers winning it and earning the right to try and defend their title as American League champs.
