OAKLAND -- Infielders and former infielders around the majors have long admired Adrian Beltre for his Gold Glove play at third base.

Now, many of them are looking at Beltre with a different kind of disbelief.

"I can't believe a guy is playing third base without a cup," said White Sox manager Ozzie Guillen, a former All-Star shortstop. "That's ballsy. That's a dangerous place, especially third base."

Vladimir Guerrero's had a rough 2009, with injury issues and his dwindling power (his .466 slugging percentage would easily be his career low if the season ended today) causing concern the 34-year-old was full-on in the middle of a career decline.

With two cracks of the bat Monday night, "Vlad the Impaler" reminded us that he's been swinging a hot stick of late. In fact, he's been the old Vlad for quite some time. He just needed to shake the Earth a little bit to ensure everyone took notice.

Starting Five is our wrapup of the previous day's baseball action, with a quick nod to what is ahead.

You Oughta Know ...
That Colorado has cycled back to the top of the NL wild-card standings.

Troy Tulowitzki hit for the cycle Tuesday as the Rockies bashed the Cubs, 11-5. By taking three of four in the series, Colorado moved a game ahead of San Francisco.

According to STATS LLC, Tulowitzki joined John Valentin as the only players ever to hit for the cycle and turn an unassisted triple play.

Tulowitzki ended up 5-for-5 with a career-best seven RBI, and he nearly had a two-homer cycle but replay upheld a foul ball ruling.

In 2005, Tom Gorzelanny pitched in the majors for the first time. He was just 22. Two years later, he went 14-10 with a 3.88 ERA -- logging more than 200 innings in 32 starts for the hapless Pittsburgh Pirates. He did allow too many hits, but he was only 25 years old, so it appeared he would settle in as an anchor for the ever-rebuilding Pirates.

Instead, he had a disastrous past two seasons and had been relegated to the minors. Last week, Gorzelanny was traded to the Cubs, and Tuesday night he passed his Cubs debut with flying colors.

As we've now witnessed a touch over a month of minor league baseball, it's worth it in many fantasy leagues to look ahead at who may be making a visit to the majors sometime this season. Remember, Ryan Braun, for example, wasn't yet in the major leagues at this point in his rookie season. This isn't to say that all of these guys -- or any -- will have that sort of an impact in the majors this year.

We're just giving a quick, non-comprehensive list of players who are playing relatively well in the minors this year and/or who have a chance to make a fantasy impact at some point. We'll start with the big names, but it won't be limited to just them. Dynasty league players should be paying the most attention.

Every season, right around this time, there is a large flock of prospects all trying to prove to themselves and the front office that they belong in big league baseball. The key to fantasy baseball success when speaking of these prospects is to know whether or not they are going to make the team out of Spring Training. If not, you need to weigh the time line of each player and figure out if he should be a selection in your fantasy draft or if you'll be spending FAAB money or using waiver priority status on him.

Choose wisely when considering the acquisition of prospects. Most of these guys have bright, rocket-ship upside. But, not all will become effective fantasy assets.

Tommy Hanson, Braves - Unless a string of injuries occur to the Braves rotation this spring, Hanson will start the season at Triple-A Gwinnett. He'll, most likely, be the first starter called up as he was a strikeout machine in the Arizona Fall League and is still showing off his arm this spring. He's good enough to make a front-of-the-rotation impact almost instantly.

FanHouse continues its 2009 MLB Preview with a look at the Oakland Athletics.

There's been an awful lot said about the non-traditional stylings of A's GM Billy Beane over the years, but his greatest asset is an absolute refusal to see players as anything more than they are. While teams like the Yankees and Red Sox pay too much to aging veterans because of ties to the franchise and other clubs clutch prospects like gold bars with absolute values, Beane coldly uses players like the assets they are before moving onto a new batch.

Fantasy baseball draft season is coming, so you best be prepared by delving through every major player on each team. Fantasy FanHouse is here to help with a quick once-over.

Meet the...
Most average team in the league. It's weird, because there don't seem to be many real weaknesses on team -- but can you really find a bunch of strengths? I hate the term "very average," but this team is pretty close to the mean across the board. As you scroll through ADP charts, you'll find the A's aren't often towards the top of the lists, but they are definitely there. As I said, average.

From now until the regular season begins, Fantasy Flings is where you'll find interesting story lines about your favorite teams from Spring Training. If there is a position battle, a nagging injury, a comeback story or a youngster making a surge for the "big club" we'll let you know the fantasy implications.

Los Angeles Angels
It turns out the Angels only rented Mark Teixeira for a few months. Now it's time to find a replacement. Kendry Morales tore up the Dominican Winter League to the tune of a .404 batting average with eight home runs and 29 RBI in only 26 games. He's also 6-17 through six Spring Training games. Nobody expects, or even asks, Morales to fill Teixeira's shoes, but the Cuban defector could blast 18 to 20 home runs and bat upwards of .280 if given full-time at-bats. He's a great late round fantasy draft flier in mixed-leagues and should be grabbed in AL-only leagues of any depth.
