Here's a look at top prospects to watch in today's Minor League action:
Hitter to watch: Clint Frazier (Indians' No. 2), Akron vs. Altoona (7:05 p.m. ET on MiLB.TV)
Frazier, No. 23 on the Top 100, enters the day having homered in back-to-back games for Double-A Akron. The 21-year-old outfielder has gone deep 11 times in 73 games, while hitting .286/.371/.488 in his first taste of the Double-A level. On Sunday, July 10, Frazier will suit up for the U.S. squad in the 18th edition of the Sirius XM All-Star Futures Game.

Pitcher to watch: Reynaldo Lopez (Nationals' No. 5), Syracuse at Durham (7:05 p.m. ET on MiLB.TV)
Lopez tossed six solid innings in is his Triple-A Syracuse debut on June 30, allowing one earned run on three hits while walking and striking out four hitters apiece. The 22-year-old righty was promoted after a dominant first half at Double-A Harrisburg, where he posted a 3.18 ERA and an Eastern League-best 100 strikeouts in 76 1/3 innings.

Duel of the day: Duane Underwood Jr. (Cubs' No. 4) vs. Andrew Moore (Mariners' No. 10), Tennessee vs. Jackson (7:05 p.m. ET on MiLB.TV)
Underwood Jr. has struggled this season at the Double-A level, going 0-5 with a 4.85 ERA in 12 starts. However, the No. 67 overall prospect was plenty good in his most recent start for Tennessee, firing six scoreless innings of four-hit ball against Jacksonville. One positive takeaway from his performance is that Underwood Jr. is missing more bats this season against advanced hitters, with 44 strikeouts in 55 2/3 innings, though it has come at the expense of an increased walk rate.

Moore has yet to record a loss since being promoted to Double-A, going 3-0 with a 3.23 ERA in seven starts. The 22-year-old right-hander was moved up to Jackson after an outstanding showing at Class A Advanced Bakersfield in the hitter-friendly Class A Advanced California League. In nine starts for the Blaze, Moore posted a 1.65 ERA and a 0.90 WHIP over 54 2/3 innings while holding opposing hitters to a .188 average.
