Here's a look at top prospects to watch in today's Minor League action:
Hitter to watch:Fernando Tatis Jr. (Padres' No. 4), San Antonio vs. Frisco (8:05 p.m. ET on MiLB.TV)
Tatis, MLB Pipeline's No. 58 overall prospect, is set to make the jump straight to Double-A San Antonio from Class A Fort Wayne. During his time in the Midwest League, the 18-year-old shortstop batted .281/.390/.520 over 117 games and set a TinCaps franchise record with 21 home runs. Overall he accrued 54 extra-base hits, as well as 78 runs scored, 69 RBIs and 29 stolen bases.
Pitcher to watch: Mitch Keller (Pirates' No. 2), Altoona at Hartford (7:05 p.m. ET on MiLB.TV)
Keller (No. 22 overall) has begun his Double-A career by allowing two or fewer earned runs over six innings in three consecutive starts for Altoona. The 21-year-old right-hander has posted 21 strikeouts against five walks in that span, all while permitting no more than five hits in an outing. Altogether, Keller has pitched to a 2.99 ERA with a 1.00 WHIP and a .205 opponents' average in 99 1/3 innings (20 starts) this season.
Duel of the day: Alec Hansen (White Sox No. 8) vs. Marcos Diplan (Brewers' No. 15), Winston-Salem vs. Carolina (7 p.m. ET on MiLB.TV)
Hansen racked up 11 strikeouts over seven one-run innings in his last start, marking his third double-digit strikeout performance in four turns for Class A Advanced Winston-Salem. The No. 100 overall prospect has emerged as one of the top strikeout artists in the Minors this season, posting 166 punchouts over 126 innings (11.9 K/9) between Winston-Salem and Class A Kannapolis. Overall, Hansen has pitched to a 2.64 ERA while holding hitters to a .206 average across 23 starts.
Diplan took a step in the right direction in his latest start for Carolina, tossing six scoreless frames of four-hit ball with a pair of strikeouts in a no-decision against Down East. The 20-year-old right-hander pitched well even though he issued five walks for the fourth time in his past seven starts, giving him 63 walks in 108 1/3 innings (5.2 BB/9) this season. On a positive note, Diplan continues to miss his share of bats (9.0 K/9) while keeping the ball in the park (0.9 HR/9).
