Astros general manager Jeff Luhnow’s first Winter Meetings are in the rearview mirror, and as he leaves Nashville, it’s time to look back and see how he did with the team’s most pressing needs:

Upgrade the Bullpen

Last season, the Astros’ bullpen was in the bottom 5 in the major leagues in ERA (5th-worst), batting average against (2nd-worst), save percentage (5th-worst), WHIP (3rd-worst), and home runs against (7th-worst). Upgrading the bullpen is at or near the top of the priority list for most GMs every offseason, and this year was no different for Luhnow.

The first thing anyone notices is the trade of Wilton Lopez to Colorado, in exchange for Alex White and Alex Gillingham. You might raise your eyebrows and wonder how the bullpen will be improved through the loss of Lopez, the team’s best reliever, but it might have been. During the Winter Meetings, the Astros added several arms, including White, Gillingham, Rule 5 picks Josh Fields and Cameron Lamb, and Mickey Storey, claimed off waivers from the Yankees (who’d claimed him off waivers themselves from Houston before the Winter Meetings.)

Storey, Fields, and White should contribute immediately to the 2013 pitching staff. It’s unclear whether White is being looked at as a starter or as a reliever, but the story on him since college is that he could be a fairly dominant reliever. What’s helpful, too, is that he’s a similar-type pitcher to Lopez, but under team control longer. Fields is a power pitcher, and Storey had a very nice season in 2012, with 10.09 K/9 and a 2.80 FIP.

Maybe the best news is that Jason Stoffel, who figures to be a good bullpen arm for the Astros in 2014 if not sooner, didn’t get taken in the Rule 5 Draft. Of course, this is through no great display of skill by Houston, but it’s noteworthy nonetheless.

Prior to the Winter Meetings, Houston had already picked up Sam Demel off waivers from the Diamondbacks.

Lamb and Gillingham won’t pitch for the big league club this season, but Storey, White, Fields, and probably Stoffel will. Without signing a single free agent or spending any real money, Luhnow & Co. at least maintained the big league bullpen, whether or not they actually strengthened it.

Jeff, please send help.

Improve the Starting Rotation

Before the Winter Meetings, the Astros went out and snagged Philip Humber off waivers from the White Sox. Heading into Nashville, it didn’t seem very likely that much else would be done to improve the starting rotation, which could benefit from a veteran presence that slots in either above or below Jordan Lyles, Lucas Harrell, and Bud Norris. Figure that the competition for the final two rotation spots is currently between Jarred Cosart, Dallas Keuchel, and Alex White.

Clearly, this is an area where the Astros could use an upgrade, even if it’s just a veteran stop-gap who can hold down the fort until Cosart’s put in some time in Oklahoma City.

There are still some veteran arms I like, including Francisco Liriano, and some more that I’ll discuss later in the week. But during the Winter Meetings, unless you consider White a potential starter, Luhnow did not address the rotation.

Pronk is a way cooler nickname than Puma.

Find a Designated Hitter

Despite reports that the Astros checked in on Lance Berkman, Travis Hafner, and Carlos Pena, no one was signed during the Winter Meetings with the express intent of playing DH for the Astros. Rule 5 selection Nate Freiman does look like someone who might be able to fill the role if no one else is signed, as he can provide pop at the plate, but I can’t even imagine that he’s Option A for anyone in the Houston front office.

The future’s so bright… you know the rest.

Though Houston came out of the Winter Meetings arguably stronger than when they went in, there are still holes to address. Still, for Luhnow’s first go-around, it was a pretty solid effort without spending any money or making any compromises.
