Tough to let go of Jair Jurjjens, but for the short term, say for the next 2-3 seasons, it's the right move. Jurjjens really had his stock rise after a couple very strong outings. Renteria immediately upgrades the short stop position defensively, but he's not outstanding. Hopefully, his bat stays as hot as it was last season. Right now, I figure he'll be in the 6th spot after Guillen, with part time lead-off work against left handed pitchers, and possibly a fill-in 3-hole hitter if Sheffield has a day off or is injured.
Overall, I'm mixed over the trade, but I do like the fact that Dombrowski was proactive in doing something. He made the deal he wanted to make to improve the line-up. Whether it works out for the better, we'll have to wait and see these next few seasons. Maggs didn't really seem like a great acquisition his first couple years here. But, if healthy, Maggs has been a spectacular free agent acquisition. Just hope Renteria can continue to hit around .300 to .315 and force pitchers to not pitch around Maggs and Guillen.
