Two years ago, the Phillies pitching rotation graced the covers of magazines, had a fancy nickname of “The Phour Aces” and was talked about as one of the best group of starting pitchers over two decades.

There was even a book written about the foursome of Roy Halladay, Cliff Lee, Cole Hamels and Roy Oswalt.

They lived up to the hype in 2011 as the Phillies won a team-record 102 games.

But the Phillies didn’t make it out of the first round of the playoffs, losing the NLDS in that decisive fifth game to the St. Louis Cardinals. Halladay allowed just one run in that game, which was one more run than the Phillies scored.

Two years has changed everything about how the Phillies’ rotation is perceived.

Halladay is no longer the ace. He will turn 36 in May and his velocity is down this spring after he dealt with lower back and shoulder issues last season, when he had his highest ERA (4.49) since 2000.

Halladay might rediscover his Cy Young form, but he hasn’t shown that this spring.

Lee is coming off an inconsistent season in which he didn’t get his first victory until July 4. Granted, that wasn’t entirely his fault. But his ERA was hovering around 4 for most of the season until he posted a 1.46 ERA in September to salvage his season.

Lee turns 35 in August and he has three years and $87.5 million left on his contract, which could become an albatross if he starts declining.

Oswalt is long gone. He had a disastrous season for the Texas Rangers and eventually got demoted to the bullpen, where he posted a 5.80 ERA. Oswalt is without a job this spring, working out at Mississippi State and hoping to latch on with a contender.

That leaves Hamels as perhaps the only ace on the Phillies staff. Kyle Kendrick and John Lannan round out the rotation.

A lot has changed with that offense, too.

Ryan Howard is 33 and is one year removed from Achilles’ surgery that deprived him of the first half of last season and affected him in the second half.

Chase Utley is 34 and coming off two straight seasons in which he missed at least seven weeks while his power production and average diminished.
