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 Jennings walked the ballpark during his occasional promotions to the majors last year, but the wildness was uncharacteristic for the lefty. A starter at the University of Nebraska, Jennings moved to the bullpen in 2009, making better use of a his two-pitch set, which involves a low-90s fastball and an above-average slider. Heíll have to outpitch the teamís other upper-minors arms to earn a roster spot out of spring training, but Jennings has the talent to emerge as a situational lefty by the end of the year.
2012 Jennings returned to Double-A Jacksonville after serving the final 11 games of the 50-game PED suspension that ended his 2010 season early. A mid-June promotion to New Orleans went poorly, with left-handers batting .349/.431/.558 against him as he struggled to throw strikes consistently, especially on the road. A strong year at New Orleans could put him in a position to take over for Choate in the Marlins bullpen when Choate's contract expires after the season.
2011 Credit the organization for not pigeonholing a guy just because he's left-handed and a reliever. The obvious temptation is to make Jennings into a situational specialist, but why cut to that particular chase when you can sort out whether his improving slider and low-90s heat works against everybody, producing tons of ground-ball outs? It seemed to be working for Jennings, up until a late-July suspension for 50 games after testing positive for methylhexaneamine, a banned stimulant. Having already served most of that, he'll be back in action in April with a great shot at erasing that mistake from most memories.
2010 A 2008 ninth-rounder, Jennings rocketed up three levels last year, propelled by a sinker/slider combo that resulted in a excellent strikeout rate and lots of grounders, as just one home run allowed in 62 2/3 IP should suggest. He doesn't blow anyone away and his control still needs a bit of refinement, so don't envision a future closer, but nonetheless he could be a solid bullpen contributor in the very near future.

DateQuestionAnswer
2014-02-11 13:00:00 (link to chat)In five years which GM has a better career win percentage since today: Dan Jennings or Jeff Luhnow?
(Billy from Ocean)
Luhnow's next five years: 66 wins, 86 wins, 83 wins, 94 wins, 90 wins.
Jennings' next five years: 66 wins, 74 wins, 93 wins (World Series), 61 wins, fired.

Luhnow. (Sam Miller)
2013-12-03 13:00:00 (link to chat)Thoughts on the Marlins-Jays trade one year later?
(David from Montreal)
Looks better for the Marlins and worse for the Blue Jays than it did at the time.

Miami freed up payroll and didn't have to deal with disappointing seasons from Bonifacio, Buck, and Johnson while netting a few interesting prospects. We'll see what Dan Jennings does this winter and throughout the season, but the young core is there to make a run sometime in the next two or three years. That's turning into a sneakily fun team to watch most nights.

Just about everything that could go wrong with Toronto's side did go wrong. Even Reyes missed considerable time due to injuries. I suppose the good news is Buehrle wasn't overwhelmed by the American League East, so the Blue Jays might have gotten two useful players out of the deal. (R.J. Anderson)
