The unsurprising happened on Thursday: Phillies general manager Ruben Amaro Jr. confirmed that second baseman Chase Utley will begin the season on the disabled list.

The thought of beginning the year without Utley is something the Phillies have been bracing for all spring. He hasn’t seen the field once yet in exhibition and with Opening Day only a week away, him starting the year on the DL was the most likely outcome.

Replacing Utley in the lineup is an impossible task. The Phillies recently signed Luis Castillo (formerly of the Mets), but he went 0-for-4 in his Philadelphia debut and may not even make the team if he continues to hit around .250 this spring. Of course, the other candidates to take Utley’s spot don’t look any better. Wilson Valdez is hitting just .239 is a 32-year-old journeyman who has only played in 247 major league games since making his first appearance in ‘04, while Josh Barfield has showed his versatility this spring but he’s still behind Valdez on the depth chart.

As of right now, the Phillies aren’t saying when Utley will return because quite frankly, they probably don’t even know. If he winds up missing the rest of the season, the loss of him and Jayson Werth (Nationals) gives the rest of Philly’s offense a small margin for error. Given that Jimmy Rollins and Shane Victorino are coming off poor seasons and Placido Polanco and Rual Ibanez are in the twilights of their careers, this is going to be a huge year for Ryan Howard (who must carry the offense).

So what happens to the Phillies’ chances of winning the World Series? Thanks to their loaded pitching staff, they’re still the clear favorites in the NL. But the Braves are a big threat in the division and there’s a certain championship team out West that treated Roy Halladay, Cliff Lee and Roy Oswalt like mortals in the postseason last year.

Of course, the Giants won the World Series last year with pitching and the Phillies have more offense than San Fran did – even without Utley. But the Giants’ hitters also got extremely hot at the right time and this is a Philadelphia club that has been known to come out of the gates slow before picking it up in the second half. Considering they might not have Utley all season, they better kick it into gear right away. Without Utley roaming second base in Philadelphia, the playing field certainly evens out more in the National League.
