BP Annual Player Comments

YearComment
2014 Due to publishing agreements, the 2014 player comments and team essays are only available in the Baseball Prospectus 2014 book (available in hardcopy, e-book, and Kindle).
2013 As they did with Jon Lieber in 2003, the Yankees signed a damaged Aardsma several months after he underwent Tommy John surgery, knowing he’d spend the season rehabbing from the procedure. The former Mariners closer made it back in time to pitch a single September inning, and the team exercised his $500,000 option for 2013, hoping for a full second season at little more than the major-league minimum. When healthy—which he hasn’t been since 2010—Aardsma depended on a mid-90s fastball to rack up enough strikeouts to survive all the walks and fly balls he allowed. If his hip and elbow surgeries have robbed his four-seamer of some speed, he’ll have to rely more heavily on his rarely seen slider and splitter to succeed.
2012 Aardsma recovered from offseason hip surgery and was rehabbing in Tacoma when his forearm started aching. Doc Yocum diagnosed it as a sprained ulnar collateral ligament but recommended rest, not Tommy John surgery. That recommendation complicates 2012, as Aardsma eventually did get shut down for the surgery in July; a second half return would be the earliest possible. The bummer for most injured closers is that most organizations have some undermarketed option who can do the job, and the incumbent's proven-closer sheen rubs off without him blowing a single save. Rather than non-tender Aardsma, the Mariners simply waived him after the World Series, giving him a few extra weeks to find a deal as a free agent.
2011 Aardsma’s 2009 season was one of those glorious relief campaigns that ends before enough innings have piled up for something to go wrong, leaving player and team alike with the nagging feeling that they might have stolen a march on the baseball gods. Despite posting one of the league’s highest fly-ball rates, Aardsma held opposing batters to just four home runs in his first crack at closing, as a succession of deep flies seemed to die on the warning track. Last season, they didn’t, and the hard thrower coughed up five long balls despite pitching over 20 fewer innings and allowing flies less frequently. Along with the expected correction in Aardsma’s home-run/fly-ball (HR/FB) rate, his strikeout rate shrunk, and his ERA was saved from further bloating only by one of the league’s lowest BABIPs. Fortunately, the righty avoided a substantial regression in his walk rate, which could have put an end to his days at the back end of the bullpen.
2010 It took until he was 27, but former first-round pick Aardsma finally mastered his command, or at least tamed it sufficiently to put together a consistent season. After losing a spring battle for the closer's job to Brandon Morrow, Aardsma picked up the job when Morrow got hurt in May and never looked back. He relied almost exclusively on his mid-90s fastball, cutting his use of the slider dramatically. The change in his style meant that he was a more extreme fly-ball pitcher than ever, as he had the fourth-highest fly-ball percentage in the 50+ IP bracket. But just four of them headed over the walls, something not just due to Safeco, as he was even harder to hit on the road, with just one homer allowed. It should also be noted that Wakamatsu handled him very carefully, bringing him in with runners on base only twice all season. Any of these factors—Aardsma's improved control, flies that don't get out, situations that don't require the closer to pitch under pressure—could change at any time. Aarsdma's 90 percent saves conversion rate may be a one-time thing, headed to the same historical dustbin as Brad Lidge's perfect season.
2009 Aardsma will take another shot at consistency this year, which would be a first, but there were plenty of positive signs in 2008. Though never an asset, his control had never before been as bad as it was in 2008, to some extent negating his high strikeout rate and improved ground-ball rate. Despite the wildness, the former first-round pick actually pitched reasonably well through mid-July, posting a 2.75 ERA in 39 1/3 innings. It was only after coming back from a groin-inspired stay on the DL that he truly got hammered, giving up 18 runs in his final 9 1/3 innings of the season, including three home runs allowed.
2008 Aardsma is one of a group of hard-throwing arms the Sox fancy they can make something out of. The same things are true about him that were true four years ago: he pumps gas and has a snappy curve, but command is a problem. To make matters worse, he rattles easily, turning a bad situation worse once men are aboard. After being demoted in early July, he didn't earn even a September cup of coffee with the big club, which doesn't bode well for his future.
2007 Aardsma made four separate trips between Chicago and Des Moines last year, repeatedly being called up and sent back as other pitchers went on and off the DL. He kept an even keel throughout, a task simplified by his limited-though-potent repertoire--virtually all fastballs, reaching up to 97 MPH. Facing a crowded bullpen, the Cubs traded him to the White Sox for Neal Cotts; he`ll have a better chance of sticking on the South Side.
2006 Part of the package received from the Giants in the fit of pique that rid the Cubs of LaTroy Hawkins, Aardsma might not fit in. His control issues seem chronic and the organization is already crowded with pitching talent. Dusty`s not known for his patience, but maybe Hendry`s hoping that the Alphabet King can harness his mid-90s heat and become the next Joe Nathan.
2005 Didn't have the instant success that fellow fast-track college closer Chad Cordero had in Montreal, but Aardsma logged a fine season at Triple-A, fanning nearly a batter per inning and keeping the ball in the park. He posted similar numbers in the Arizona Fall League, though he looked wild for stretches. He's expected to win a bullpen job in '05, and he's got the arsenal for a high-leverage or closer job.

DateQuestionAnswer
2013-04-16 20:00:00 (link to chat)How do I value Addison Reed if I just started a dynasty rebuild? I know closers should be the first thing to go in a rebuild, but I can't help but believe he's relatively stable and likely to help me when I compete again in 2-3 years. Thanks
(JoeTinker from Chicago)
Here is a list of all closers who recorded 25 or more saves in 2010: Brian Wilson (48), Heath Bell (47), Rafael Soriano (45), Joakim Soria (43), Matt Capps (42), Neftali Feliz (40), Francisco Cordero (40), Carlos Marmol (38), Billy Wagner (37), Jonathan Papelbon (37), Kevin Gregg (37), Mariano Rivera (33), David Aardsma (31), Juan Oviedo (30), Bobby Jenks (27), Ryan Franklin (27), Brad Lidge (27), Jose Valverde (26), Francisco Rodriguez (25) and Andrew Bailey (25).

2013-01-29 14:00:00 (link to chat)Is the Yankee bullpen deep enough to overcome the loss of Soriano?
(Alex from Anaheim)
Thanks for coming back, Alex.

With Mariano Rivera, and David Aardsma and Joba Chamberlain in the mix, I don't think the Yankees will miss Soriano too much, provided that at least two of those three righties are healthy. Also, to throw in a little Top 10 prospect lingo, keep in mind that they have a potential "Factor on the Farm" in Mark Montgomery. (Daniel Rathman)
2012-01-18 13:00:00 (link to chat)If Seattle moves Brandon League mid-season, who takes over as the M's closer?
(PepeShady from St Paul)
The obvious candidate is George Sherrill, given his previous closer experience. If he bombs... David Aardsma might be rehabbing by then.

Also, quick use of dianagram's ESC trick has shown me that Aardsma's sister is attractive. -- Dave (Best of BP with Ben and Dave)
