Inbox: Will A's Barreto move to second? Montas to 'pen?

Jim Callis answers fans' questions about baseball's future stars

November 11th, 2016

Going through game withdrawal? You can stave it off for at least another week with a pair of Arizona Fall League games.
On Saturday at 8 p.m. ET, MLB Network and MLB.com will broadcast the AFL's annual Military Appreciation Game, which this year features the Peoria Javelinas visiting the Salt River Rafters. The following Saturday, Nov. 19, at 3 p.m. ET, MLB Network and MLB.com will carry the AFL Championship Game. Roughly 60 percent of Fall Leaguers go on to play in the Majors, so each of those games will feature in the neighborhood of 18-20 future big leaguers.

I've seen a good deal of A's Nos. 1 and 10 prospects Franklin Barreto and Frankie Montas with the Mesa Solar Sox. Barreto isn't having a good Arizona Fall League, though his bat speed and line-drive approach (albeit one which could use more patience) are apparent. He's not particularly smooth or quick as shortstop, so he likely will wind up at second base, a position at which the Athletics don't have a clear-cut starter for the long term.
Montas has been one of the most impressive pitchers in the AFL. I saw him for the second time on Tuesday, when he worked three shutout innings while hitting 101 mph with his fastball. He hasn't allowed a run in 14 1/3 innings and has held opponents to a .116 average while sitting in the upper 90s with his heater and the upper 80s with his cutter/slider.
Scouts have been divided on whether Montas will wind up as a starter or a reliever since he was with the White Sox two trades ago. Oakland just acquired him from the Dodgers in the / deal in July and is just worrying about getting him innings right now after he missed most of the regular season with rib issues. He doesn't have much of a track record of durability or control, which likely points him to the bullpen, but he has looked like a viable rotation option when he's at his best.

Jorge Mateo, the Yankees' No. 3 prospect entered the season as one of the top shortstop prospects in baseball, but played second base almost exclusively after the Yankees acquired in the trade in July. Torres stayed at shortstop after joining Mateo at Class A Advanced Tampa. The two youngest regulars -- and two of the better players -- in New York's big league lineup are and , so there's a good chance Mateo's final destination could be center field.
Mateo's top-of-the-line speed would fit nicely in center, and his plus arm would be an asset at a position that lacks strong throwers in general. His stock has taken a bit of a hit after he batted .254/.306/.379 in Class A Advanced and got suspended for insubordination, but he's also just 21 and still has the tools that earn him comps to an in-his-prime . The Yankees also have a lot of young outfielders with having arrived in the Majors and and Blake Rutherford (among others) on the way, but Mateo's talent should earn him a spot somewhere in New York.

To me, the fact that Dylan Cozens and Rhys Hoskins, Nos. 6 and 12 on the Phillies' Top 30 Prospects list, are in the Dominican Winter League rather than the Arizona Fall League is a sign that the Phillies are trying to expedite their development. The Dominican League will give them more at-bats (because of more games and more regular playing time) against better competition than they would get in the AFL. The caveat is that DWL teams put a higher priority on winning, so Cozens and Hoskins will have to produce to stay in the lineup.
Helped by a hitter-friendly park in Double-A Reading, Cozens led the Minors in homers (40), RBIs (125), extra-base hits (81) and total bases (308) while Hoskins ranked second in homers (38) and third in RBIs (116). Hoskins is performing better in the Dominican, batting .273/.385/.473 with three homers in 15 games for Cibao. Cozens is hitting .206/.296/.460 with four homers in 17 contests for Aguilas.

Second base for the Dodgers is in a state of flux. has become a free agent, and just headed out of Los Angeles via trade. The Dodgers have a good farm system but no prospects ready to step in at second, so their 2017 starter very likely isn't a member of the organization at this moment.
The Dodgers' No. 4 prospect Willie Calhoun, who hit 27 Double-A homers in his first full pro season, is one of the game's best second-base prospects -- but he doesn't have the defensive chops to stay there and probably will wind up in an outfield corner. Los Angeles' best internal bet for a second baseman of the future is either Gavin Lux, a 2016 first-round Draft pick, or Omar Estevez, a Cuban defector who signed for $6 million a year earlier.
