Eric Longenhagen is publishing brief, informal notes from his looks at the prospects of the Arizona Fall League and, for the moment, the Fall Instructional League. Find all editions here.

Braves 2B Travis Demeritte has looked tremendous at second base this fall. Not only has he made several acrobatic plays but he’s handled some bad hops and sucked up errant throws on steal attempts as well. While his hands remain somewhat rough, Demeritte’s range and athleticism have forced me to reckon with the idea of plus-plus defense at second base — as well as to remember if I’ve ever put a 7 on a second baseman’s glove before. I don’t think I have, and I suppose it’s worth asking if such a thing even exists, as one might wonder why a 70 or 80 glove at second base couldn’t play shortstop in some capacity. I think the right concoction of skills (chiefly, great range and actions but a poor arm) can churn out a plus-plus defender there. I’d cite Ian Kinsler, Brandon Phillips and Dustin Pedroia, and Chase Utley as examples from the last eight or 10 years. It’d be aggressive to put a future 7 on Demeritte’s glove right now because his hands and arm accuracy are too inconsistent, but those are things that could be polished up with time.

Tigers RHP Spencer Turnbull was up to 94 and mixed in five different pitches last night. Nothing was plus and Turnbull doesn’t have especially good command but I liked how he and Brewers C Jake Nottingham sequenced hitters and how to and that Turnbull was willing to pitch backwards and give hitters different looks each at-bat. He and Rays RHP Brent Honeywell have the deepest repertoires I’ve seen so far in Fall League.

Giants righty Chris Stratton sat 89-92 last night with an average mid-80s slider that is good enough to miss bats if he locates it, and last night he did. I think the changeup is average, as well, while Stratton’s curveball is a tick below but a useful change of pace early in counts. He looks like a back-end starter.

Quite a few defenders got to air it out last night. Here are some grades I put on guys’ arms:

Dawel Lugo, 3B, ARI: 6

Miguel Andujar, 3B, NYY: 6

Pat Valaika, INF, COL: 5

Gavin Cecchini, INF, NYM: 45

Christin Stewart, OF, DET: 4

Angels CF Michael Hermosillo, who was committed to Illinois to play running back before signing with Anaheim after the 2013 draft, displayed tremendous range in center field last night. He looks erratic at the plate but he hit well at Burlington and Inland Empire this year and is an obvious late-bloomer follow as a two-sport prospect from a cold weather state.
