The fact that Reid-Foley, 20, has gone 5-0 with a 1.88 ERA in seven starts for Dunedin, despite struggling in his stint for the squad last year (5.23 ERA in eight starts), speaks to how he's improved. The right-hander owns a 0.77 WHIP and a 54-9 strikeout-to-walk ratio through 43 innings, during which he's yielded just two home runs while holding opposing hitters to a .159 average.
Reid-Foley was promoted to the Florida State League in mid-June after a strong showing at Class A Lansing, where he logged a 2.95 ERA with 59 strikeouts across 58 innings (11 starts).
Improved control and command have defined Reid-Foley's breakout campaign, as he's issued just 31 free passes in 101 innings after walking 67 hitters over 96 frames during his 2015 full-season debut. The 2014 second-rounder is 9-3 with a 2.50 ERA, a 0.97 WHIP and 113 strikeouts in 18 starts between the two levels.
The rest of the best performances from top prospects Tuesday
• Making his first Triple-A start, No. 1 overall prospect Lucas Giolito picked up the win for Syracuse as he allowed one unearned run on seven hits over 6 2/3 innings against Gwinnett. The Nationals' No. 1 prospect recorded seven strikeouts against two walks and generated nine ground-ball outs, throwing 70 of his 104 pitches for strikes.
• No. 32 overall prospect Raul Mondesi (Royals' No. 1) Mondesi fell a single short of the cycle on Tuesday afternoon, finishing 3-for-5 with three RBIs in Triple-A Omaha's win. The home run was his first in nine games since being promoted from Double-A Northwest Arkansas, and he also stole his first base at the Triple-A level.
• Both No. 41 overall prospect Ryan McMahon (Rockies' No. 3) and Raimel Tapia (Rockies' No. 6) went 4-for-5 at the plate with two extra base hits and two RBIs as Double-A Hartford hammered Altoona, 10-2. McMahon slugged his seventh homer, a solo shot in the second inning, and later added a double, while Tapia hit a pair of doubles in his third four-hit performance of the season.
• No. 92 overall prospect Justus Sheffield (Indians' No. 5) fired 6 2/3 scoreless innings for Class A Advanced Lynchburg, matching his season high, in a win versus Wilmington to lower his ERA to 3.53. The 20-year-old lefty scattered four hits and punched out eight, giving him 87 strikeouts in 89 1/3 innings (18 starts) for the season.
• No. 94 overall prospect Matt Chapman (A's No. 3) went 4-for-5 with a career-best three doubles and four RBIs to power Double-A Midland in a 14-2 rout of Corpus Christi. The 23-year-old third baseman has struggled of late, going 2-for-24 over his last six games before erupting for four hits.
• No. 97 overall prospect Joe Musgrove yielded six hits over seven scoreless innings in his finest start as a member of Triple-A Fresno. With a season-high nine strikeouts and zero walks, the Astros' No. 7 prospect improved his strikeout-to-walk ratio to 71-9 through 71 1/3 innings between the Double-A and Triple-A levels.
• Dodgers No. 15 prospect Willie Calhoun has showcased his power in his first full pro season, and that's never been more true than it was in Double-A Tulsa's 7-1 win over Northwest Arkansas, as he went 2-for-4 with a pair of home runs. The 2015 fourth-rounder has 19 homers in 88 games this season, during which he's hit .259/.322/.482 with 61 RBIs.
• Giants No. 21 prospect Ty Blach pitched brilliantly for Sacramento, tossing six one-hit innings in a 1-0 shutout of New Orleans. The 25-year-old left-hander did not issue a walk, struck out three and induced nine ground-ball outs (including one double play) en route to facing 19 hitters -- one over the minimum. Blach has logged 30 innings during his four-start winning streak for the River Cats, striking out 22 and walking one in that span.
• It was a special day for a pair of Nationals prospects, as Andrew Stevenson (No. 8) and Drew Ward (No. 14) hit their first Double-A homers in Harrisburg's 5-2 win over Erie. It was just the second home run of the season for Stevenson, while Ward went deep for the 12th time.
• Padres No. 28 prospect Luis Urias extended his hitting streak to 13 games and connected on his fifth home run for Class A Advanced Lake Elsinore. It was the second straight three-hit game for the 19-year-old second baseman, who finished 3-for-4 with a double and a walk and scored three runs. Urias is raking at a .336 clip for the Storm this season.
