Baseball's No. 16 overall prospect has been some kind of hot lately, hitting safely in 21 straight games for Double-A Altoona. He has tallied an extra-base hit in each of his past five contests and has 20 during his streak, including all five of his home runs. The 21-year-old center fielder is raking at a .415 clip over his last 21 games for the Curve, during which he's raised his average to .310 from .192.
Diplan, 19, has been outstanding this year in his full-season debut while operating as part of Class A Wisconsin's piggyback starting rotation. The right-hander has pitched to a 1.89 ERA across his 12 appearances (six starts), with 64 strikeouts and 24 walks in 47 2/3 innings. He's allowed two home runs in that span while holding opposing hitters to a .188 average.
Duel of the day: Kohl Stewart (Twins' No. 7) vs. Jen-Ho Tseng (Cubs' No. 24), Chattanooga at Tennessee (12:05 p.m. ET on MiLB.TV)
Stewart is set to make his third start for Double-A Chattanooga. Though he struggled in his Lookouts debut, the 21-year-old right-hander rebounded to toss six scoreless innings in his next outing on June 9. Prior to his promotion, Stewart had registered a 2.61 ERA over 51 2/3 innings (nine starts) for Class A Advanced Fort Myers.
Tseng will be making his second start for Double-A Tennessee since being activated from the disabled list. In his previous turn, the Taiwanese right-hander allowed two runs over five scoreless innings, striking out five, against Mississippi.
