Here's a look at top prospects to watch Thursday in Minor League action:
Hitter to watch: Ian Happ (Cubs' No. 3), Tennessee vs. Montgomery (8:05 p.m. ET on MiLB.TV)
Happ, the No. 66 overall prospect, is off to a fast start at Double-A. Happ was promoted after hitting .296 in 69 games with Class A Advanced Myrtle Beach, and the hits have continued to come in bunches. The second baseman went 2-for-4 Wednesday and, despite a three-game stretch where he went 0-for-12, is batting .364 through 18 games with the Smokies.

Pitcher to watch: Erick Fedde (Nationals' No. 4), Potomac vs. Winston-Salem (7 p.m. ET on MiLB.TV)
The 23-year-old right-hander appears to have figured it out. Fedde's ERA sat at 6.62 on May 22, but it has dropped to 4.13 after his recent string of quality outings. The Nationals' prospect has allowed one run or less in each of his last six appearances, five of which were starts. Fedde is coming off a performance in which he allowed just one run on three hits over six innings while striking out eight.

Duel of the Day: Brad Markey (Cubs' No. 28) vs. Chih-Wei Hu (Rays' No. 12), Tennessee vs. Montgomery (8:05 p.m. ET on MiLB.TV)
Markey has adapted just fine to life at the Double-A level. The 24-year-old has a 2.59 ERA and has allowed two earned runs or fewer in 13 of his 15 starts. The right-hander threw six scoreless innings in his last outing and will look to string together some more zeroes against a Montgomery team that he fared well against earlier in the year (nine innings pitched, three earned runs in two starts).

Hu has thrown very well against the Smokies this season and will look for a repeat performance after struggling a bit in his last outing. In two starts against Tennessee, Hu has allowed one earned run in 11 innings. The 22-year-old has lost his last six decisions, but his 2.51 ERA in six Double-A starts indicates he's pitched better than his 2-6 record indicates.

Wednesday's Top 100 probables:

No. 31 Dillon Tate (Rangers' No. 3), Hickory vs. Lakewood (Class A)
