Here's a look at top prospects to watch Wednesday in Minor League action:
Hitter to watch: Cornelius Randolph (Phillies' No. 6), Lakewood vs. Hickory (7:05 p.m. ET)
Randolph has started to rack up hits in rapid succession. The 19-year-old went 2-for-3 in Game 1 of Lakewood's doubleheader Tuesday and has hits in 10 of his past 12 games. Randolph has multiple hits in five of those games and is 6-for-13 over his past four contests.
After a couple of shaky starts, the No. 4 overall prospect returned to form in his last outing. Giolito gave up one run on three hits in six innings. The 22-year-old right-hander spent the bulk of the season in Double-A, but made one start at the Class A level and started three games in the Majors. Giolito made his Triple-A debut on July 19 and is 1-2 with a 3.38 ERA in four starts with Syracuse.
August has been a good month for De Leon and the 24-year-old right-hander will look to keep that going against Albuquerque. De Leon has a 2.77 ERA and 12 strikeouts in 13 innings in two starts this month, while limiting opponents to a .208 batting average. De Leon's season got off to a late start after he sprained his ankle in Spring Training, but when he's been on the mound, he's performed worthy of his No. 39 overall ranking. De Leon is 5-1 with a 3.20 ERA in 13 starts.
Marquez's stellar July (3-0, 2.21 ERA in five starts) helped prompt a promotion to Triple-A, but the 21-year-old's debut at the new level didn't go quite as planned. Marquez had a shutout going through six innings, but was unable to finish the seventh and was charged with four runs. The Rockies' prospect has struck out seven or more in each of his past four starts and will take the mound looking for a better showing with his new club.
