Adding to the fire of speculation, Nick V mentioned in the shoutbox that, according to ESPN1000, Jim Hendry may also be looking at Marlins players Scott Olsen and Jeremy Hermidia.
I'd be a little surprised to see that trade happen because the Cubs probably lack the kind of prospects Florida is seeking. However, after thinking about it I have to think that it is exactly the kind of trade that might happen.
It's typical for baseball fans to focus on the trades and acquisition of name players, if only because we already know who they are and that makes it easier to talk about. But while a Jake Peavy trade has to be unlikely - even if Colin says it might not be - a trade for two young players who most Cub fans aren't familiar with but have a good amount of promise and talent is incredibly more likely to occur. Here's a closer look at Hermidia and Olsen:
Scott Olsen - 24 year old LHP, 8-11, 4.20 ERA, 201.2 IP, 113K, 69 BB
Olsen has never really had an outstanding season, but as a younger pitcher that can't really be held against him. He certainly wouldn't have the same impact as a Peavy, but I have to figure he's likely to outperform Marquis next season at a fraction of the cost.
Jeremy Hermidia - 24 years old, LHB, .249 AVG, 17 HR, 61 RBI, 48 BB, 138 K, .323 OBP, .729 OPS
Hermidia didn't have a great year last season, but in 2007 he batted .296 with 47 walks and 18 homeruns in 429 at bats. As a young lefty, he's probably ideal for what Jim Hendry is looking for while allowing Hendry to free up salary room to upgrade elsewhere. It's conceivable that, once relocated away from the cavern in Miami, Hermidia will blossom.
Nick V failed to mention what the Cubs might surrender to acquire these two players, but Marshall and Pie seem the likeliest of candidates - assuming they aren't included in any trade for Peavy.
