Here's a look at top prospects to watch in today's Minor League action:
Hitter to watch: Matt Chapman (A's No. 6)
Chapman opened eyes this spring in big league camp with the A's by hitting six home runs in 44 at-bats -- this after he hit 23 homers in 80 games in 2015. The 22-year-old third baseman has continued his slugging ways at Double-A Midland, for which he's hit four homers in 13 games -- three in his past four contests -- while batting .279/.436/.628. On Friday, Chapman will face rehabbing big leaguer Brandon Morrow as the RockHounds take on San Antonio in a game that can be seen on MiLB.TV at 8:05 p.m. ET.
Pitcher(s) to watch: Lucas Giolito (Nationals' No. 1) and Julio Urias (Dodgers' No. 1)
Though there are plenty of Top 100 pitchers scheduled for Friday, all eyes will be on Giolito and Urias, MLBPipeline.com's Nos. 1 and 2 overall prospects, as each makes his third start of the season. Giolito (1-0, 1.17 ERA), coming off an outing in which he allowed three hits over just 3 2/3 innings for Double-A Harrisburg, will look to get his season rolling when he pitches against Bowie at 7:05 p.m. ET on MiLB.TV. An hour later, Urias (1-1, 3.60 ERA) will take the hill for Triple-A Oklahoma City against Memphis at 8:05 p.m. ET on MiLB.TV. The 19-year-old left-hander was dominant against the Redbirds in his season debut, when he allowed four hits and struck out nine in five scoreless innings.
Duel of the day: Sean Manaea (A's No. 2) vs. Jorge Lopez (Brewers' No. 3)
A pair of Top 100 prospects will square off Friday night on MiLB.TV in Lopez (No. 55) and Manaea (No. 66), who are scheduled to start for Triple-A Colorado Springs and Nashville, respectively, at 8:35 p.m. ET. A winner in both of his starts for the Sounds, Manaea enters the day with a stellar 1.50 ERA and a 17/2 K/BB ratio through his first 12 innings. Lopez (0-0, 6.48 ERA), meanwhile, has allowed three earned runs in both of his starts for the Sky Sox, neither of which has seen the 23-year-old righty complete five innings.
