BP Annual Player Comments

YearComment
2012 Jenks's disappointing biceps strain doesn't sound so bad when you consider what he has been through since the season ended. He underwent off-season surgery to repair a calcified ligament causing nerve damage in his spine. The ligament was discovered while treating Jenks for colitis, but surgery could not be performed immediately thanks to a pulmonary embolism in Jenks's lungs. Thankfully, Jenks is expected to be healthy and ready to go in the spring. Assuming he is indeed the Jenks of old, with the way the closer market exploded this past winter, his two-year, $12 million contract all of a sudden looks fantastic even with the lost season in mind.
2011 There comes a point where a high-maintenance relationship is no longer worth the time required to keep it going. Jenks has slowly become that kind of guy, especially after a 2010 season in which he struggled with calf, back, and forearm injuries, the last ending his season a month early and scotching a bid for 30 saves. The main positives are that he still throws hard, and that he got his strikeout and his ground-ball rates back up where they'd been during his early-career glory years. If you want to believe that the BABIP fairy will smile on him while he keeps his strikeout rate up, you're probably also willing to keep waiting for that initial magic to come back, too. Having spent as much time as they have waiting for it, the Sox could be forgiven their decision to non-tender Jenks a year before free agency.
2010 The offseason on the South Side had plenty of drama before the postseason even ended, as Jenks and general manager Kenny Williams traded barbs about what went wrong in 2009, with Williams pointing the finger at Jenks' bulging waistline. While this was possibly some politicking for what could be an acrimonious arbitration hearing, the White Sox don't necessarily need that much ammo—Jenks clearly isn't the pitcher he was as recently as two years ago. Neither radar guns (nor scales) lie, and what was once a 96-98 mph fastball that could touch 100 is now 92-95, making Jenks, on a pure stuff level, more of a set-up man.
2009 Jenks' maturation has been fascinating to watch, as he’s followed an unusual path. Once a wild, fire-balling starter, he’s turned into a contact-pitching closer who doesn’t hurt himself with walks and gets his opponents to pound his heater into the ground. Over the past two seasons, Jenks has allowed just five homers and walked just 30 men in 126 2/3 innings, while striking out just 6.7 men per nine frames despite his high-90s heat. Jenks missed three weeks in July with scapula bursitis and had a rough September, but still finished eighth in the majors in WXRL.
2008 The Human Barrel was the one effective member of the Sox's pen last year, as Jenks silenced doubters with his best year yet, in no small part because of his record-tying 41 straight batters retired (joining 1970s Giants starter Jim Barr at the head of the class). Remove those 41 consecutive outs from his record, and his season line was a still-dominant .242/.291/.301. The secret to his success was that he started putting his fastball in the zone with much more regularity. That meant both fewer walks and fewer strikeouts, but it's was a worthwhile tradeoff as it's almost impossible to catch up with and pull his heater. It might not be beyond the realm of possibility for him to improve yet again this year; he was raw when he first got to the Sox in 2005, after all, and he's really only just putting everything together.
2007 Perhaps the biggest indication of how far Bobby Jenks has come is that his 2006 season was a little . . . boring. His ERA was somewhat higher than expected, but the save total and peripherals were spot on. He slumped in July and again in September, but there was no sign of a mental or physical breakdown. Jenks will never move into the Rivera-Wagner-Hoffman class of relievers without some radical improvement to his command, but he significantly improved his ground ball rate last season, which helps keep those walks from doing damage via three-run homers. He should remain a good closer, provided one remembers that `good` in this division and this ballpark can mean a 3.60 ERA.
2006 The curious case of Bobby Jenks can be as simple or as complicated as you want it to be. Forget the checkered personal history, the postseason heroics, the beer gut, the at-bat that might be responsible for Jeff Bagwell`s retirement. The bottom line is this: if Jenks can keep his walk rate below four walks per nine, he`ll succeed, and if he can`t, he won`t. He was just above that threshold in Birmingham last year, and just below it in Chicago. A purely statistical projection isn`t of much help here. To the extent that ballplayers have personal issues, 90 percent of them boil down to self-confidence, and it`s hard to imagine a bigger confidence boost than getting the last out of the World Series. Ozzie Guillen is also a big piece of the puzzle. When Scott Podsednik hit his walk-off to win Game 2 against the Astros, Guillen`s first instinct was not to congratulate Pods, but to find Jenks in the crowd and to make sure that he was doing okay after blowing the save earlier. Almost inevitably, there will be moments that require the same finesse and compassion next season, and Guillen, who makes no pretension of being a perfect man, is the right manager to provide it.
2005 Taking up space on the 40-man roster like a car that's been booted, Jenks missed most of the season with a "stress reaction," the precursor to a stress fracture. It's the second time he's been shelved for this reason, and pins have been inserted into his elbow in hopes that these will hold it together. As in the old TMBG song, Jenks throws sapphire bullets of pure love, topping 102 mph in winter ball. Unfortunately, the speed is as untamed, as 6.2 walks per nine attest. He looked great at Double-A Arkansas in 2003, but he now has three hurdles—personality/maturity, health and control—to jump before he can have a notable major league career. Those are long odds. Claimed on waivers by the White Sox, who haven't had a lot of success turning minor league projects into major league pitchers in recent years. The odds just got longer.

BP Chats

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). (Bret Sayre)
2011-08-04 13:00:00 (link to chat)What's scarier, today's stock market meltdown or Tim Wheeler's picture on MiLB.com?
(MJ from Madison, Wis.)
Aye caramba: http://web.minorleaguebaseball.com/milb/stats/stats.jsp?pos=LF&sid=milb&t=p_pbp&pid=572254

Still not as bad as Bobby Jenks' pic at ESPN or here. Cripes what a terrible beard. (Jay Jaffe)
2011-05-26 13:00:00 (link to chat)We already know Epstien is one of the best GMs in baseball. Can't argue with 2 rings in 10 years. What do you think of how his moves from last off season are panning out?
(Puppy-D from BAWSTON)
I was a bit stunned to see Sam Fuld still outhitting Carl Crawford a few days ago. I think he is pretty delighted to have Adrian Gonzalez on his squad, though, and eventually Crawford will turn it around. Now, if they can just get Bobby Jenks and Dan Wheeler healthy, the offseason could look about as good as it did in March. (R.J. Anderson)
2011-05-26 13:00:00 (link to chat)Bard seems to pitch well most of the time, but then will have some periods where he seems to lose his control or have problems with lefties. Can he take over from Paplebon as closer next year?
(Bruce from toronto)
Even if he's not, the Red Sox will still have Bobby Jenks sitting around. Also, I think most relievers go through stretches similar to Bard. (R.J. Anderson)
2010-12-07 13:00:00 (link to chat)Will Chris Sale begin in the bullpen to start the season?
(richardkr34 from St. Paul)
Considering they lost Putz and non-tendered Bobby Jenks, I would think so. He probably won't take the closer role right away, but he will definitely start the year in the pen. Ozzie still likes him as a reliever last I saw. (Marc Normandin)
2008-12-11 14:00:00 (link to chat)Thanks for taking the time for the chat. We all know there have been substantial talks with a couple of teams regarding Jermaine Dye, but is there any information on players like Bobby Jenks, Paul Konerko, and Jim Thome, who are all possibilities to be traded this offseason?
(Ben from Work)
It appears that the White Sox are going to hang on to Jenks now and there never seemed to be much of a market for Konerko and Thome, who both have no-trade clauses. (John Perrotto)
2008-01-14 13:00:00 (link to chat)Will, as I ponder curveballs, I ask you : is there such a thing as really "clean" mechanics on a curve that won't build to injury? And if there are, is it possible to throw, say a Doc Gooden yakker or a Bobby Jenks curve with them?
(Justin Fox from New Jersey)
Yes, there are solid mechanical principles behind safely pitching a baseball, whether that's a curve or any other pitch. The difference is that in putting all of the pieces together, there's similar but different results. Think about it -- there's almost no two curve balls or sliders that are exactly alike. There's so much character in them, so much individuality, that it's a fun game to talk about. I recently watched a video of Gooden and was stunned that his curve looked more like a Zito "loop" than I remember early in his career; I'd remembered it as more of a Lincecum power curve that stayed low and "dropped off the table."

As for mechanics, yes, there are good, clean mechanics, but there's not "one true mechanic." (Will Carroll)
2008-01-14 13:00:00 (link to chat)Adam Loewen: Will the screw in his arm effect his longevity? Will it put him at risk for a by-product injury? Can he still have the power arm? Other than Cal Eldred, who else has pithced with a screw in his arm? How is he doing? Thanks.
(ButkusSayers from Chicago)
I could be wrong, but I think the screw was removed. There have been a couple pitchers who have had similar injuries -- Derrick Turnbow and Bobby Jenks come to mind -- and I think Loewen should come back pretty effectively. He's "on schedule" and should be throwing at the same pace with the other pitchers when the Orioles open camp. (Will Carroll)
