BP Annual Player Comments

YearComment
2013 Cook is a fire extinguisher on the 20th floor of a building engulfed in flames: It’s there if you need it, but if you need it, you’re probably already screwed. Cook’s status in Boston was a placeholder for a better starting pitcher who didn’t materialize. The offseason is a chance to find that pitcher, though, so if Cook is starting in Boston this season the front office didn't do its job or somebody got hurt. Cook stands out for more than general lousiness. His 1.91 SO9 is the second lowest for a starting pitcher since the DH was instituted in 1973, right behind the decidedly mortal Larry Pashnick’s 1.81 for the Tigers in 1982.
2012 When healthy, Cook has succeeded in the Colorado rotation for the better part of a decade despite poor strikeout rates. He is a big guy whose finesse approach would make him an innings eater except for the fact that injuries have kept him from eating innings. Cook has topped the 170 mark just twice in his career, and shoulder and finger issues delayed his 2011 debut to June 8. He didn't fool anyone last year, posting the worst ERA of his career. Cook is the most strikeout-averse pitcher in the big leagues, filling the void created when Kirk Rueter retired in 2005. Cook's main challenges now are the same as they've always been: Stay healthy enough to make it through an entire season and keep thriving despite allowing an extraordinary number of balls in play while pitching in baseball's most favorable offensive environment. The odds are against him, but that has been true for a long time.
2011 One of the requirements of succeeding as a pitch-to-contact ground-baller like Cook is actually making batters swing, but in 2010, Cook’s walk rate crept perilously close to his strikeout rate, and his ERA scooted up as a result. That relative wildness was unrelated to the sprained right big toe that contributed to his 8.31 ERA from July 7 to August 3 and landed him on the disabled list for a month thereafter: Cook had 39 walks against 43 strikeouts before that skid. Two starts into his return from the toe injury, a comebacker off the bat of Joey Votto fractured his fibula, ending his season. The oft-injured righty should be healed by spring training.
2010 A helpful reminder that strikeouts aren’t everything, Cook gives up a lot of hits but doesn’t walk anyone and relies on his 90 mph sinker to get ground balls, which the Rockies’ top-notch infield defense turns into outs. A strained shoulder kept him on the shelf for most of September, but he came back strong to win his last two starts and should come into 2010 healthy. Such a low strikeout rate leaves little margin for error—a few more lucky hits or a defensive slump will play havoc with Cook’s ERA—but odds are he’ll continue to soak up innings and be a solid mid-rotation starter.
2009 The All-Star Game demonstrated what Aaron Cook is in a nutshell. He allowed seven base runners over three innings but didn't allow a single run because of his knack for inducing grounders. Cook will mix in about 10 to 15 sliders a game, but otherwise, he's all about the sinker, a pitch which he adds and subtracts from to assist in its deception, throwing it anywhere from 87 to 93 mph. He gives up a lot of hits, but he doesn't walk anyone, and again, there are always those ground balls, which truly are a pitcher's best friend. It's a bit of a high wire act, but Cook is so good at it as to be an honorary Flying Wallenda.
2008 Cook, who has one of the lowest strikeout rates in baseball, was the biggest beneficiary of the Rockies' improved defense in 2007. The 13-point drop in team BABIP was reflected in his decreased batting average against. With his ability to control the running game and get double plays, Cook can survive like this for a while. Having given him a new four-year, $36.4 million extension that runs through 2011, the Rockies are banking on it.
2007 The National League`s answer to Chien-Ming Wang, Cook also relies heavily on a mid-90s sinking fastball to force hitters to beat the ball into the ground nearly 60 percent of the time. Also like Wang, Cook had a strong season despite a strikeout rate that ranked lowest among qualifiers in the league. His unusual control for a sinkerballer and ability to induce groundballs allows him to succeed even with a STUFF score that bears little resemblance to the actual quality of his pitches. Also like Wang, Cook is dancing at the edge of a precipice, and any loss of velocity or command will be unusually destructive.
2005 He's never put up the big strikeout numbers you like to see, but he did have a fairly nice year, all things considered. A 4.28 ERA in roughly half a season's worth of work in Coors is worth a handshake and a pat on the back. Is he likely to keep it up? Well, he didn't have tremendous control, but he did keep opponents from hitting the ball over the fence, which is a good thing. Still, the numbers look more like David Fleming than David Wells. He's out until at least the beginning of June after surgery to remove a rib that was impairing his circulation.
2003 The drop in strikeouts was semi-intentional. Cook used to blow hitters away with 98-mph heat, but Bob McClure got hold of him and taught him to emphasize placement over power. Cook never gets rattled, and induces a lot of ground balls and fouls off the batter’s body. He threw back-to-back shutouts before his promotion to Triple-A. On May 5, Mark Prior came to town and had a good day but Cook outpitched him. You wouldn’t know it based on what he did in the majors last year, and Coors will mask his talent for a while, but he’s going to be good.
2002 Cook, the Rockies' second-round pick in 1997, has moved very slowly through the system. He has the best fastball in the Rockies' chain, topping out at 98 mph. His good year was helped by his development from thrower to pitcher, as he used his slider more. Cook looks good but will need to strike out more batters to become a serious prospect.
2001 High-school pitchers are risks. From an organizational point of view, it’s tough to hang your hat on them because they take longer than any other kind of player to develop. Brian Bohanon was a first-round pick in 1987 and didn’t really make it until ten years and three surgeries later. Aaron Cook was a second-round pick in 1997 and had his first good season by repeating Asheville. A hard thrower, he showed improved command of his fastball and slider, but needs to work on changing speeds. The Rockies should not be in any rush to get him to Double-A.
