After he gave up a season-worst six earned runs in his last start, Sean Reid-Foley returned to form Tuesday as he fired six innings of one-hit ball to lead Class A Advanced Dunedin in a 2-0 shutout over Charlotte.
Reid-Foley, the Blue Jays' No. 3 prospect, struck out the side in his first and last innings of work and fanned 10 of the 21 hitters he faced, marking his third start this season in which he's recorded double-digit strikeouts. He recorded five ground-ball outs and walked a pair, while throwing 57 of his 90 pitches for strikes.
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

• 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 prospectTy Blach pitched brilliantly for Sacramento, tossing six one-hit innings in a 1-0 shutout of New Orleans.

Blach has logged 30 innings during his four-start winning streak for the River Cats, striking out 22 and walking one in that span.
