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 third 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 West…

Oakland Athletics:

1. Brett Anderson (4-2 2.57 ERA, 25 Strikeouts)
2. Jarrod Parker (13-8, 3.47 ERA, 140 Strikeouts)
3. Tommy Milone (13-10, 3.74 ERA, 137 Strikeouts)
4. A.J. Griffin (7-1, 3.06 ERA, 64 Strikeouts)
5. Bartolo Colon (10-9, 3.43 ERA, 91 Strikeouts)

Average Combined 2012 ERA: 3.25

Texas Rangers:

1. Yu Darvish (16-9, 3.90 ERA, 221 Strikeouts)
2. Derek Holland (12-7, 4.67 ERA, 145 Strikeouts)

4. Alexi Ogando (2-0, 3.27 ERA, 66 Strikeouts)
5. Martin Perez (1-4, 5.45 ERA, 25 Strikeouts)

Don’t forget, the A’s (not the Angels or Rangers) are the reigning champs of this division after shocking the baseball world and making a historic run to enter the postseason. But I think that the lack of a “star” pitcher will hurt the A’s this season, as they will no longer be running under the radar like last year. But as for the Angels, I believe that although they may have lost three fifths of the starting rotation they put on the field last year, they did a pretty decent job filling the holes. Tommy Hanson and Jason Vargas are good alternatives for Zack Greinke and Ervin Santana. Joe Blanton had his moments with Greinkes’ new team, the Dodgers last year after being dealt. Look for them to all have decent years.

As for the rest of the division, I do believe that the AL CY Young winner will come from this division in the form of Mariner pitcher Felix Hernandez. He will be the bright spot in what is shaping-up to be another disappointing season for Seattle. The division will be a three team race between the Angels, A’s and Rangers, ultimately with the Angels coming out on top, but I wouldn’t be surprised if either the Rangers or A’s sneak into one of the wild card spots. The Angels have had huge spending off seasons consecutively and this will be the year that it pans out and they reach the postseason.
