Stynes filled in nicely at third last season with a .334 BA and hitting 12 round trippers. He qualifies at 3rd, but is very versatile which could mean quite a few at-bats in Beantown. He does have speed even, though he didn't show it much last year. He's a decent pickup in late rounds and could fill in for your fantasy team at several positions. He is still being bothered by that knee, but not to the point that it will keep him out for an extended period of time.
Knee injuries are tricky, especially for the pivoting a corner guy has to do in the field.
He will have to sit on occasion to rest the weak joint. If he can go, he'll bring you a .260 to .270 average with a couple of dozen home runs. He may be a forgotten man in your league. Now, at the age of 27, he may never hit the long ball consistently. He does bring to the table an excellent batting average, over .300 in the last two seasons.
