Gavin Lux's tremendous season (.347/.421/.607 between Double-A and Triple-A at age 21) got me to wondering about the last middle infielder that young to post a 1.000 OPS as a full-season batting qualifier in the Minors. As it turns out, it was his current double-play partner on the Dodgers, Corey Seager, who batted .349/.402/.602 as a 20-year old in Class A Advanced and Double-A in 2014.

And that got me to wondering about the last middle infielder as young as Lux to record a 1.000 OPS in the upper Minors. That took considerably more digging to discover it was Gregg Jefferies, who hit .367/.423/.598 as a 19-year-old in Double-A in 1987.

Between Jefferies and Seager, the only other middle infielders with four-digit OPS were Marcus Giles (1998), Howie Kendrick (2005), Brandon Wood (2005) and Jose Altuve (2011).

I always enjoy a good lineup-oriented question. The toughest position to settle was third base, where I ultimately took Alec Bohm (Phillies) just barely over Nolan Gorman (Cardinals), Nolan Jones (Indians) and Josh Jung (Rangers) because Bohm has the best chance to hit for both power and average. With Lux in Los Angeles, second base was up for grabs and I gave Vidal Brujan (Rays) the edge over Nick Madrigal (White Sox) because Brujan is faster and may have a little more pop.

Here's my lineup, which includes two of the first three picks in the 2019 Draft:

Adley Rutschman, C, Orioles
Andrew Vaughn, 1B, White Sox
Vidal Brujan, 2B, Rays
Alec Bohm, 3B, Phillies
Wander Franco, SS, Rays
Jo Adell, OF, Angels
Jarred Kelenic, OF, Mariners
Luis Robert, OF, White Sox

Marquez's $600,000 bonus in 2015 was the largest given to any international left-hander that summer, and it looks like a bargain for the Cubs four years later. The Dominican unquestionably has the highest ceiling among Chicago's pitching prospects and made huge strides toward reaching it this summer.

In his last seven starts of the season, the 20-year-old Marquez logged a 1.17 ERA, 48/8 K/BB ratio and .163 opponent average over 38 1/3 innings. He repeatedly ran his fastball into the triple digits, devastated hitters with a power slurve and made progress with his changeup. He has the upside of a No. 2 starter, and that might be conservative if he can command his pitches like he did down the stretch.

A couple of weeks ago, I broke down the top 15 college prospects and the top 15 high school prospects for the 2020 Draft. As of now, the three prime candidates to go No. 1 all come from the college ranks.

The consensus is that Georgia right-hander Emerson Hancock (who's similar to 2018 No. 1 overall choice Casey Mize) and Arizona State first baseman Spencer Torkelson (who parallels 2019 No. 3 overall pick Andrew Vaughn) are 1 and 1A. Vanderbilt third baseman Austin Martin, who might be the best pure hitter in the 2020 class, could work his way alongside them next spring. The two best high school prospects are both right-handers, Jared Kelly (Refugio, Texas, HS) and Mick Abel (Jesuit HS, Portland, Ore.) -- and no prep righty ever has gone No. 1 in the Draft.

While Garcia has flown under the radar since signing for $5 million as a Cuban defector in June 2017, he's blossoming into one of the Reds' better position prospects. After looking overmatched at the plate in his pro debut last year, he hit .280/.343/.436 with 37 doubles as a 21-year-old in Class A Advanced in 2019.

Garcia has gotten much stronger since signing and packs considerably more than the listed 175 pounds on his 6-foot-2 frame. He needs a more disciplined approach but has the potential to hit 20 homers per season while providing plus speed, a cannon arm and the ability to get the job done at shortstop. Cincinnati has invested heavily in infielders (Jonathan India, Rece Hinds, Tyler Callihan) in the last two Drafts, so Garcia gets overshadowed, but he could become a solid big league regular in a couple of years.
