Jimmy Rollins

Anticipation grew as the players exited the tunnel Monday to enter Citizens Bank Park to mark the 2010 Philadelphia Phillies' home opener against the Washington Nationals.

Above, Jimmy Rollins, the longest-tenured player among the Phillies, enters among adoring fans.

Moments later, however, a hush grew among the gathered fans.

Juan Castro, not Jimmy Rollins, took the field at shortstop.

Not since Lenny Dysktra broke his wrist on Opening Day many years ago did such a key member of the team go down on Opening Day.

With one week of the regular season behind us, what have we learned about the 2010 edition of the Philadelphia Phillies so far? A week is a just a week, but how a team plays and what story lines unfold once the big curtain goes up on the games that count often foreshadow the season.

The Philadelphia Phillies' 2-1 win over the Houston Astros on Sunday was a bit of an oddity for the National League's hottest team.

It was the first time all season that the Phillies have no gotten at least 10 hits.

No matter. Their ace, Roy Halladay was on the mound, giving up one unearned run in a seven-hit, no walk, eight strikeout performance. Oh, yeah, and it was Halladay's first complete game of the season.

The Phillies pounded out six hits, featuring Jimmy Rollins's home run to start the game and a Carlos Ruiz ground-out RBI in the second inning.

In the final game of the Phillies-Astros series, Philadelphia Phillies pitcher Roy Halladay, who pitched a complete game on Sunday, seems to be in mid-season form.

With offensive help coming from Jimmy Rollins, thanks to his solo home run to start the game off, and Carlos Ruiz's second-inning sacrifice ground ball that sent Raul Ibanez home, for the Phillies second and last run of the game.

When the Phils lose, don’t get down. I’ve found that a really fun way to pass the time is to go to the pet shop, find a big cage of mice, and watch them fight for position on their wheel. Seriously. It’s hysterical. It doesn’t even take mind-altering drugs to enjoy a curious mouse getting damn near decapitated by an ambitious team on a wheel.

This was not the debut that Cole Hamels had been hoping for. From all the hype of his spring training progress you half-expected him to go out and throw a no-hitter, and since it was against the lowly Washington Nationals, it might as well have made it a perfect game. 

Instead, Hamels labored through 5 innings. He gave up 5 hits, walked 4, and allowed 2 earned runs. It did not look pretty, but he was effective enough, and most importantly he didn't allow the "big inning" that plagued him during his 2009 campaign. 

Every year as a Phillies fan, I’ve grown accustomed to saying “wait until next year.”

Next year we’ll pick up a big-name player in free agency. We’ll overtake the Braves or Mets in the division race. We’ll get a couple of good breaks, stay healthy all season, and win it all.

Guess what?

It happened.

This will begin my 2010 MLB preview. I intend to touch every team in the major leagues in installments by division. The lineups I provide will be what I predict will be the most productive for each team for the MAJORITY of the season (e.g., Jason Heyward will be listed as the Braves RF even though he may not begin the season as the starter).

I will also provide the stereotypical letter grade to each team's lineup, rotation, bullpen, and bench. Though it is trite, I think all baseball fans can identify with the letter grade system.

In this two part series, I will rank the top players in the National League East. The rankings were made through the analysis of statistics such as batting average, on base percentage, slugging percentage, and on base plus slugging percentage.

Several other factors were also taken into consideration such as age, injury, and defensive ability.

There are some situations where the players are so closely ranked, it is nearly impossible to decide between.

My earliest memories of Phillies baseball were of muggy, rain-delayed July games at Veterans Stadium, with the season already a lost cause, and where the few thousand (drunk) fans in attendance huddled in the dark concrete concourses of the Vet.
