2012

The Cubs' best and most consistent reliever over the last two years, Marshall even picked up five saves when Carlos Marmol imploded last summer. At 6-foot-6 and left-handed, Marshall's picked up his velocity of late, (average fastball was 91.3 mph), has excellent command (79:17 K:BB in 75.2 innings) and keeps the ball on the ground (2.6 GB/FB ratio, one home run allowed). One of the first moves the new Cubs regime made was to trade Marshall to the Reds for Travis Wood, Dave Sappelt and Ronald Torreyes. The Reds subsequently signed Ryan Madson to close, leaving Marshall as a high-leverage reliever for the seventh and eighth innings. He's one of the elite relievers in the National League in that capacity.

2011

Marshall had a fantastic year as a reliever in 2010, with a 90:25 K:BB ratio in 74.2 IP, only three homers allowed and an ERA of 2.65. The 6-foot-6 lefty isn't a hard thrower, but pitching out of the bullpen allowed him to boost his velocity to the low-90s, and the sinking action (2.33 G/F) kept the ball in the park. There's some talk Marshall will be given a shot to return to the rotation, but given his effectiveness in the bullpen, we'd be surprised if that happened.

2010

Marshall had a brief stint in the rotation last year, but eventually lost out to rookie Randy Wells and became a key lefty out of the bullpen. The 6-foot-6 lefty isn't overpowering, but his command is good, and he relies on a sinker to induce groundballs (1.84 G/F). He'll compete for the fifth starter's job in camp with Tom Gorzelanny and, to a lesser extent, Jay Jackson and Jeff Samardzija.

2009

The 6-foot-6 lefty has been effective for two seasons now, posting good K:BB numbers, and even boosting his strikeout rate last season (36:12 K:BB ratio in 39 IP as a starter). Marshall uncharacteristically gave up as many flyballs as grounders last year, and his home-run rate spiked as a result. But given the relatively small sample, and his reliance on a sinker, we wouldn't make too much of that. Marshall's already a better pitcher than Jason Marquis and would make an above average fifth starter - the spot he'll be vying for this spring - if he's not traded.

2008

The 6-6 lefty took a step in the right direction in 2007, cutting down his walks, nudging up his strikeout rate while doing a decent job of keeping the ball on the ground. At age 25, Marshall still has room to grow -- he's never going to be a staff ace, but by keeping the ball down and improving his command, he could be a serviceable middle of the rotation option. He'll head into spring training as a candidate for the No. 5 slot in the team's rotation, but will have to beat out Ryan Dempster, Sean Gallagher and Kevin Hart.

2007

Like Carlos Marmol, Marshall was pressed into duty before he was ready by injuries to Cubs pitchers. The results were predictably poor. He didn't struggle quite as badly as his teammate because he was able to generate some ground balls and keep the walks merely unacceptably high and not disastrously so. Still, the 6-6 lefty doesn't dominate enough at this stage to get by with average command. We suspect he'll join Marmol in the minors for most of 2007.

2006

After struggling during his first taste of Double-A in 2004, the 6-6 lefty went back to High-A to start 2005 before getting his second chance at the high minors in late June. In four Double-A starts spanning 25 innings, Marshall had a 24/5 K/BB ratio, an ERA of 2.52, a WHIP of .84 and allowed just one home run. The usual sample size caveats apply, but if Marshall picks up at where he left off this spring, he could find himself with the big league club by September.
