Here's a look at top prospects to watch in today's Minor League action:
Hitter to watch:Tyler O'Neill (Cardinals' No. 4), Memphis at Round Rock (2:05 p.m. ET on MiLB.TV)
MLB Pipeline's No. 94 overall prospect belted a pair of two-run home runs and a double on Friday in Triple-A Memphis' win over Round Rock, and then connected on another two-run shot in his second at-bat Saturday for the Red Birds, giving him three in his first three games.
Pitcher to watch: Mitch Keller (Pirates' No. 1), Altoona vs. Akron (2 p.m. ET on MiLB.TV)
Keller, MLB Pipeline's No. 16 overall prospect, will be making his season debut when he takes the mound for Double-A Altoona. The 22-year-finished his impressive 2017 campaign in the Eastern League, posting a 3.12 ERA and a .197 opponents' average with 45 strikeouts in 34 2/3 innings (six starts). Altogether, he pitched to a 3.03 ERA, while averaging nine strikeouts-per-nine innings, in 116 frames across three levels.

Duel of the day: Peter Lambert (Rockies' No. 5) vs. Sean Reid-Foley (Blue Jays' No. 10), Hartford vs. New Hampshire (1:05 p.m. ET on MiLB.TV) (Double-A)
Speaking of debuts, Lambert, 20, is set to make his first Double-A start against a New Hampshire lineup that could include phenoms Vladimir Guerrero Jr. and Bo Bichette, MLB Pipeline's Nos. 3 and 13 overall prospects. Spending all of 2017 in the Class A Advanced California League, Lambert posted a 4.17 ERA with 18 home runs allowed, but also 131 strikeouts in a career-high 142 1/3 innings (26 starts).

Reid-Foley, meanwhile, is returning to New Hampshire after struggling in his first Eastern League exposure last season. Making 27 starts, the 22-year-old right-hander logged a 5.09 ERA, while posting 122 strikeouts against 53 walks, in 132 2/3 frames. A ground-ball pitcher early in his career who yielded just eight homers in his first two full-season campaigns, Reid-Foley saw that total spike to 22 last year with the Fisher Cats.
