Here's a look at top prospects to watch in today's Minor League action:
Hitter to watch: Rhys Hoskins (Phillies' No. 19), Reading at Portland (6 p.m. ET on MiLB.TV)
Hoskins connected on his Minor League-leading 20th home run on Friday night in Double-A Reading's win over Portland. It was the 23-year-old first baseman's third straight game with a home run, and he's now gone deep 12 times in 22 games this month. Meanwhile, by going 2-for-5 with three RBIs, Hoskins lifted his season average and OPS to .278 and .897, respectively, and he's now plated 59 runs in 69 games for the Fightin Phils.

Pitcher to watch: Stephen Gonsalves (Twins' No. 6), Chattanooga vs. Jackson (7:15 p.m. ET)
Gonsalves, No. 100 on the Top 100, is set to make his Double-A debut today after a dominant first half in the Florida State League. The 21-year-old left-hander pitched to a 2.33 ERA over 11 starts for Class A Advanced Fort Myers, with 66 strikeouts and 20 walks in 65 2/3 innings. On top of that, Gonsalves has allowed just two home runs while holding opposing hitters to a .188 average in that span, during which he owns a 0.96 WHIP.

Duel of the day: Duane Underwood Jr. (Cubs' No. 4) vs. Rookie Davis (Reds' No. 12), Tennessee vs. Pensacola (7:05 p.m. ET on MiLB.TV)
Inefficiency has prevented Underwood Jr., 21, from working deep into games in his first Double-A exposure, as he's completed six innings just once in 10 starts for Tennessee. The No. 69 overall prospect's 0-4 record, 5.12 ERA and 1.73 WHIP certainly leave something to be desired, but he's still managed to miss bats at a high rate, piling up 40 strikeouts in 45 2/3 innings.

Davis, meanwhile, is set to make his fifth start for Pensacola since returning from a stint on the disabled list for a strained groin. He's 5-1 with a 2.39 ERA in 52 2/3 innings (10 starts).
