The 2012 Milwaukee Brewers season has been in the books since Wednesday, but over their final few games I asked fans over Twitter a few questions about the team.

I specifically wanted to know what surprised them, what disappointed them, and what they look forward to in 2013.

The overriding disappointment for the season, not surprisingly, was the performance of the bullpen for four months. Despite not making the playoffs after beginning the season with those expectations, the team has ended the season on a positive note by securing the fourth winning season in the last six years.

"When we looked at where we were and where we finished up and being able to see a lot of young guys going into next year that we have some decisions to make, I think it was successful," Brewers manager Ron Roenicke said. "I'm not happy with the season. Nobody's happy with the season. ... They all have a positive attitude about where he finished up and I think that was important going into next year."

Below are some responses from the Tweeps, as well as the Brewers themselves.

@jimowczarski Fiers was big.How about Gomez becoming a full fledged starter w/near 40 stolen bags and nearing 20 FREAKING HOME RUNS? — Derek Harvey (@SecondHandStore) September 30, 2012

Carlos Gomez finished the year as one of five players in the majors this season with 15 or more homers and 30 or more stolen bases, joining Mike Trout, B.J. Upton, Jimmy Rollins and Ryan Braun.

In his sixth season in the Major Leagues, Gomez hit .260 with 42 extra base hits – including 19 homers – and 37 stolen bases. He also had an on base percentage over .300 for the first time.

"Now I recognize and now I know what I'm doing," said Gomez, who played in 137 games. "Before, it was just ability. I would just go in and play with my ability. Now, I step out and think about what they're trying to do to me. It's the kind of thing that will make you a better hitter."

@jimowczarski Aoki hitting the crap out of the baseball. — Jerry Eldred (@jheldred) September 30, 2012

After starting the year on the bench, then playing his way out of a platoon role into the everyday starting lineup, 30-year-old rookie Norichika Aoki led the National League with 18 extra-base hits in September, which also tied the September franchise record.

"Looking back right now, I started off coming off the bench and it was kind of a tough situation especially coming from starting every game in Japan," Aoki said through translator Kosuke Inaji. "I'm kind of surprised that I actually chose this route but I've always wanted to play over here and I'm glad I made that choice."

Aoki also was the first NL rookie since Bake McBride (1974) to have four different 10-game hitting streaks while ranking at or near the top of all NL rookies in stolen bases (30), hits (150), runs (81), doubles (37) and total bases (225).

"Nothing was really surprising," Aoki said. "Looking at the numbers right now, I guess it's something that not really expected but I'm not surprised. That's the best that I was able to do this year."

@jimowczarski Gotta be Aramis. A move that at first looked like a disaster ended up being a bargain this season. — Zachary J. Loesl (@mmm9731) September 30, 2012

Aramis Ramirez got off to one his patented slow starts, but the 34-year-old not only emerged from it to finish with a .300 average, he had an overall historic season by a Brewers third baseman.

Ramirez's 103 RBI surpassed Casey McGehee's 102 for the franchise record, and it also marked the seventh time in his career he's topped 100 RBI season. He also led the league in doubles (50) and was at or near the top of the NL in extra base hits (80), RBI (105) total bases (308) and slugging percentage.

"Aramis had a phenomenal year. He really did. All the way around," Ryan Braun said. "He played great defense. I really think he's deserving of the Gold Glove this year. Was just incredibly consistent."

@jimowczarski Good surprises: Aoki, gr8 defense by Aramis, Corey's awesomeness at 1B, Gomez offensive production. Disappointment? Bullpen. — Amy Williams (@BrewerGirl823) October 3, 2012

@jimowczarski Hart at first base on the positive side. K-rod/Ax on the negative side (And Braun not getting any MVP mentions). #brewers — Lloyd Rutherford (@2dmbigo) September 30, 2012

The season was just weeks old when first baseman Mat Gamel tore his ACL, moving Corey Hart from the outfield grass to the infield dirt. He gutted out injuries to his knee and foot to play 149 games – his most since 2008 – and hit 30 homers and drive in 83 runs while hitting .270.

In his 103 games at first, he posted a respectable .995 fielding percentage and 7.74 range factor and an above average league range factor per nine innings at 9.29.

"I played well but definitely still wasn't as comfortable as I want to be," Hart said. "It definitely helped that I could go over there and perform, and for me that's big. I still have a lot to learn and a lot to improve on. I'm pretty excited with the fact I did well and I'm still learning. I'm excited for what lies ahead."
