Offseason Movement: The ‘Stros signed Aaron Boone in the offseason, but he recently announced that he’s scheduled to undergo open heart surgery and therefore his season, if not his career, is over. Houston also added pitchers Mike Hampton and Clay Hensley, as well as outfielder Jason Michaels and shortstop Jason Smith.

Top Prospect: Jason Castro, C
The 21-year old catcher was the first of five draft selections for Houston in 2008. Castro has flashed good plate discipline and if he develops, could add power to an already above-average bat. He probably won’t blow anyone away defensively, but he’s more than adequate behind the dish and should make a solid overall player in the future.

The Big Question: Where’s the pitching?
Roy Oswalt is a freak – a true No. 1 starter who usually gives the Astros a win every five days and halts losing streaks with ease. But after him, the starting rotation looks awfully bleak. Mike Hampton is never healthy, Wandy Rodriguez strained an oblique muscle earlier this spring and Brian Moehler hasn’t looked particularly great to this point. The fifth spot in the rotation is up for grabs between Brandon Backe, Russ Ortiz and Jose Capellan. Yikes.

Outlook: The Astros’ lineup is pretty solid. Kazuo Matsui has good speed, Hunter Pence has above average power (although he needs to lift his average quite a bit), Lance Berkman is one of the best switching hitters in baseball and Carlos Lee continues to drive the ball out of the park and knock in runs. Geoff Blum also had a career-high in home runs last year with 14 and Michael Bourn has demonstrated the ability to get on base. The bullpen is solid as well, led by closer Jose Valverde, who topped the NL last year in saves with 44. But after Roy Oswalt, the starting rotation could be the worst in baseball and that’s why Houston is destined to finish near the bottom of the NL Central Division. They just don’t have enough quality arms and while there are things to like about the lineup, the offense just isn’t good enough to carry this club on its own. Oswalt is also a candidate to be dealt at the trade deadline.

Projection: 5th NL Central

#1 Chan Ho Park Signed by Texas in 2002, five years, $65 million.
Coming off 18-10 and 15-11 seasons in the pitchers’ heaven that is Dodger Stadium, Texas gave Park one of the most lucrative contracts ever given to a pitcher at that time. Injuries limited his workload, which wasn’t a bad thing considering his ERAs with the Rangers: 5.75, 7.58, 5.74, 5.66, before he was finally unloaded to San Diego in 2005.

#2 Juan Pierre (signed by Los Angeles in 2006, five years, $44 million) and Andruw Jones (signed by Los Angeles in 2007, two years, $36.2 million).
You know it’s a really bad signing when the team inks someone a year later to play the same position, and he does even worse. Pierre took his below-league-average on-base ability and minuscule power into the offensive void of Dodger Stadium with predictable results: .664 and .655 OPS in his two seasons so far. Andruw Jones received a raise off his worst season in 2007, and demonstrated that bad year in Atlanta was no fluke, batting .158 with three home runs in 209 at bats in 2008. The Jones signing also shifted Pierre to left field, where his wretched bat for a centerfielder would be an even greater liability. By the end of the season, the Dodgers recognized their CF answer had been there all along, in the person of Matt Kemp.

#3 Mike Hampton and Denny Neagle – Signed by Colorado in 2000; Hampton for eight years, $121 million, Neagle for five years, $51 million.
The vertiginous problem of pitching in Colorado led to some terrible decisions. Even though importing a free agent had failed in the case of Darryl Kile (ERAs of 5.20 and 6.61 in his two seasons before he was traded to St. Louis), the Rockies tried again in the 2000-01 offseason, giving $172 million to two lefthanders. Hampton was hampered by injuries and ineffectiveness in his two seasons in Colorado, going 21-28 with ERAs of 5.41 and 6.15 before being shipped off to Florida (and then on to Atlanta); his free-agent contract finally expired last year. Neagle was a decent 31-year-old pitcher with a 105-69 record and 3.92 career ERA when the Rockies elevated him to the front of their rotation; he gave them three seasons of 19-23, 5.56, before earning his release with two years left on his contract.

I’m a little surprised Barry Zito didn’t make the list, but I guess people are willing to give him one more year of brutal pitching before really laying the hammer on the massive free agent bust.
