Washington Nationals' Top 10 Minor League Prospects Update

Statistics as of July 14 courtesy of Baseball-Reference.com and MILB.com. Ages listed are "season age," meaning age they'll be at end of season.

1. Lucas Giolito (age 21): Giolito made his much anticipated big league debut with two decidedly different starting appearances, then was sent back to the minors for reinforcements when Ryan Zimmerman went on the D.L. In Giolito's first appearance he went four shutout innings on one hit and two walks against the Mets. Nine days later he was roughed up by those same Mets for four runs on seven hits and four walks in just 3 2/3 innings. The top prospect in the Nats' organization has yet to make an appearance for AAA Syracuse yet since being demoted on July 8.

2. Trea Turner (age 22): Turner was recalled to the Nats on July 8 as part of those reinforcements to cover Zimmerman's injury. He played in one game before the All-Star break, going 0 for 4 against the Mets in Sunday's 3-2 win. Before that, he was still tearing up AAA. In June he hit .284 (39 of 137) with nine doubles, three triple and three home runs. He drove in nine, walked 16 times and was goo don 9 of 11 stolen base attempts. How long he stays up and where he plays and how often is still kind of a mystery, but as we've been saying in this space for a while, he has nothing left to learn in the minors at the plate.

3. Victor Robles (age 19): Robles was promoted to Potomac on June 27 after hitting Low-A pitching for a .305/.405/.459 slash with 20 extra base hits (5 homers) and 19 steals in 27 tries. So far for the P-Nats, Robles is hitting .222/.315/.349 in 15 games and is 7 of 9 in stolen base opportunities. He has two homers and seven RBIs, with seven walks against 11 Ks.

4. Reynaldo Lopez (age 22): Lopez is another prospect that was promoted since our last installment -- from Harrisburg to Syracuse. In two starts for the Chiefs, Lopez is 1-0 with a 3.27 ERA and 1.364 WHIP with nine strikeouts in 11 innings. He completed his AA season at 3-5 with a 3.18 ERA and 1.231 WHIP with 100 Ks in 76 1/3 innings (11.8 K/9).

5. A.J. Cole (age 24): Cole keeps plugging away at Syracuse at the end of June he put together a string of three games where he gave up two, one and two earned runs, but in his last appearance was clobbered for seven earned runs on six hits and three walks in 3 2/3 innings. For the season, Cole is 6-5 with a 4.84 ERA and 1.455 WHIP with 76 Ks in 89 1.3 innings (7.7 K/9, 2.9 BB/9). He's treading water and a move to the bullpen fulltime is likely if he isn't traded again.

6. Erick Fedde (age 22): Fedde made an adjustment after a crummy start on May 15 and he's been lights-out since. In his last six starts he's given up three earned runs (never more than one in a game) and struck out 26. His last time out on July 8 he went six innings and allowed one run on three hits and a walk, striking out eight. For the season, Fedde is 5-3 with a 4.13 ERA and 1.197 WHIP with 61 strikeouts in 61 innings.

7. Wilmer Difo (age 24): The once-heralded Difo has been slogging through a mostly forgettable season for AA Harrisburg, but he's been better of late. In his last 10 games, he's hitting .375 (15 of 40) and driven in eight, including a four-RBI game in a 14-3 win against Erie. For the season,though, Difo's slashing just .252/321/.337 with four homers and 26 of 35 steals. He's stalled in a big way.

8. Anderson Franco (age 18): Hit .269/.346/.389 with four homers, 21 walks, 28 strikeouts in 193 at-bats between GCL and NY-P in 2015. At 6-foot-3, 190 lbs, he should grow into the frame and some scouts think he'll develop 20-homer power, already drawing comparisons to the Phillies' Maikel Franco (no relation).

9. Austin Voth (age 23): Voth continues to have a productive year at Syracuse. His last appearance on July 8 he threw five shutout innings on four hits, though he did walk six. Overall, Voth is 4-5 in 17 starts with a 3.24 ERA and 1.223 WHIP with 83 strikeouts over 97 1/3 innings

10. Andrew Stevenson (age 22): Stevenson was promoted from Potomac to Harrisburg and so far he's been overmatched at AA. The LSU product is slashing .183/.210/.183 in 62 plate appearances in 13 games with two steals in three attempts and no extra-base hits.
