We’re just over 48 hours away from the start of the 2013 MLB regular season, and I couldn’t be more excited. Baseball fans everywhere are making final predictions as to how they feel things will play out, as players are making their final preparations for the long 162 game season. As my last blog post until the season begins, I wanted to do a brief overview of the top story lines I’m planning to keep an eye on in 2013. They may differ slightly from yours, but I feel I covered nearly all of the major topics:

1. How the Astros will fare in the American League:

Having lost 107 games in the National League in 2012, I’m watching the Astros, not for how good they’ll do, but for how bad they’ll do. Sorry to any Astros fans reading this post, but there’s no denying that the odds are against the Astros going into the 2013 season. Playing in one of the toughest divisions in baseball, with the newly revamped Angels, they’re likely to have just as bad of a season as last year, if not slightly worse. I’d say it would be considered a good year for the Astros if they finish with less than 100 losses.

2. If Bryce Harper and Mike Trout can keep up their 2012 R.O.Y. seasons:

Posting some incredible stats, leading to one of the best rookie seasons in MLB history, I’m going to keep a closer eye on Mike Trout than I am Bryce Harper, but I’m planning to watch Harper nonetheless. Both won the Rookie of the Year award in 2012, for their respective leagues, and it should be interesting to see if their amazing rookie years will transfer into the 2013 season. I’m predicting Trout will once again have a 30/30 season, with Harper possibly recording the first 30 home run season of his career.

3. Who will hit the most home runs in 2013:

The 2012 home run leaders consisted of Miguel Cabrera, Curtis Granderson and Josh Hamilton, as the 1-2-3 guys, and if it wasn’t for an injured Granderson, I could see all three being near the top of the rankings again in 2013. However, with Granderson out with an injury for the first portion of the year–while I see Cabrera once again leading all players in homers, with Hamilton coming in a close second–it will likely be a new face who will round out the top three. Maybe it’ll be a guy like Adam Dunn, who’s a free-swinger? Or maybe a guy no one saw coming, who will have a breakout season? It will certainly be fun to keep track of.

4. If A-Rod comes back healthy, if at all:

While it’s 100 percent certain that Alex Rodriguez won’t return to the Yankees’ lineup until late July, there is the slight chance that he could miss the entire season. However, if A-Rod is able to work his way back this season, after having hip surgery in January, it should be very interesting to see if he can become a decent player once again. While Rodriguez will never be the great player he once was, if healthy, he has the ability to make an impact for the Yankees. Although I’m not the biggest fan of A-Rod, I still hope he comes back healthy. But I find it very unlikely that he will ever again play at a competitive level.

5. How the rookies, such as Wil Myers, will impact their teams in 2013:

I discussed this a couple months ago, in my blog post on the Top 100 prospects going into the 2013 season, but this time around I’m only focusing my attention on a handful of rookies who I feel will have the biggest impact for their team this season. Wil Myers is the number one guy on my radar, with Shelby Miller, Jurickson Profar and Billy Hamilton being the other three main rookies I plan on keeping track of. Myers was the minor league player of the year, in 2012, and I fully see him posting more of the same stats, as he begins the the year with AAA Durham. Of the four, Miller is the only player that is starting in the majors to begin the year, but they should all make it to the big leagues at some point this season, and are sure to each play a key role in their teams’ success.

6. How the Upton bro’s do for the Atlanta Braves:

You could argue that, with the addition of both Justin Upton and B.J. Upton to roam the outfield with Jason Heyward, the Braves have the best all-around outfield in all of baseball. All three players have great range, giving them the ability to make plays on balls that other outfielders couldn’t get to, but furthermore, they all have the talent to impact their team offensively as well. Both Upton’s, as well as Heyward, have the ability to blast 25+ home runs and 85+ RBI’s, as well as steal a good amount of bases. If they can perform to their potential this season, combined with the great lineup and pitching rotation they already had, the Braves could be an outstanding team.

7. What kind of a year players who ended 2012 injured will have in 2013:

The reason A-Rod had his own category, and wasn’t included in this one, is merely because his return is uncertain. All of the players in this category didn’t play at all after their injury in 2012, and will make a guaranteed comeback, within at least the first few weeks of the season. With that said, the most impactful players to end last season with an injury, that I’ll be watching in 2013, include Derek Jeter, Troy Tulowitzki and Mariano Rivera.

Mariano Rivera tore his ACL in May, while Derek Jeter fractured his ankle in October, with neither playing any more games for the remainder of the year. Rivera is expected to be ready to go Opening Day, though a slight setback for Jeter will force him onto the disable list to begin the year. In my opinion, the 2013 performances of both Jeter and Rivera will be the deciding factor for what kind of season the Yankees have. If Jeter can return quickly, and Rivera can post his usual stellar numbers, I see the Yankees being just fine.

Troy Tulowitzki injured his groin in May of last season, and although it appeared he would return towards the end of the year, he remained sidelined for the remainder of the season. A healthy Tulowitzki can impact the Rockies more than nearly any other player in all of baseball, though he hasn’t been able to stay healthy for the majority of his career. While I can’t see the Rockies finishing any better than last in their division, I’m planning to watch “Tulo” nonetheless, to see if he can finally have a successful, fully healthy season.

8. How the Blue Jays, Dodgers and Angels perform with their new additions:

The Blue Jays, Dodgers and Angels made the biggest splashes of nearly every other team in all of baseball this past offseason; at least of the teams that stand a chance of competing. Many have the Blue Jays going the distance, and winning it all, with the key additions of Jose Reyes, Melky Cabrera and 2012 Cy Young winner R.A. Dickey, to name a few, though I don’t see it happening. I find myself siding more with the opinions of those who are betting on the Dodgers and Angels to have a great season.

The Angels’ major addition of the offseason was undoubtedly Josh Hamilton, who, with the help of Mike Trout and Albert Pujols, has the ability to transform the Angels into an extremely competitive team. Hamilton might end up being the piece the Angels were missing last season, that will help them make the playoffs in 2013.

The number one addition of the offseason for the Dodgers was Zack Greinke, though they also acquired Hyun-Jin Ryu, the highly praised LHP from Korea. Adding them both, to go along with their already deep pitching rotation, could end up making the Dodgers a team to be reckoned with in 2013.

9. Whether or not the Nationals make it to the World Series:

Last season, Nationals’ manager, Davey Johnson, made the bold statement that he should be fired if the Nat’s didn’t make the playoffs in 2012. Luckily for Johnson, they did, for the first time since 1933. This season, however, it’s “World Series or bust” for the Nationals, and although I was a bit skeptical last year, I’m not putting it past them to make it all the way to the World Series this season, for what would be the first time in Nationals’ franchise history. With a fantastic lineup, as well as one of the best starting rotations in all of baseball, they should go far in the coming season, though they’ll have to make it past the favorited Braves, who many (myself included) have winning the division.

10. Which team(s) will have an unexpected breakout season:

Every season, it seems, there is a team or two that unexpectedly takes the baseball world by storm. On paper, they shouldn’t be winning, but yet they come together as a team and are able to do amazing things. The 2012 example would be the Oakland Athletics and the Baltimore Orioles, as the majority of baseball fans, going into the 2012 season, didn’t see the O’s and A’s exploding the way they did. Truly showing that baseball is extremely unpredictable. Any team has the chance to defy the odds, which is part of what makes baseball so great. Anything can happen.
