Newsmakers from Wednesday's action:

Walker Buehler, rhp, Dodgers. The Dodgersí top prospect had a better time of it in his second Triple-A start than his first.

Overall at three levels, Buehler is 2-3, 3.33 with 100 strikeouts in 70.1 innings.

Michael Kopech, rhp, White Sox. Another hard-throwing righthander showed well Wednesday as Kopech fanned a career-high 12 in six innings in Double-A Birminghamís 3-1 win over Chattanooga (Twins). Since his impressive outing at the Futures Game, where he touched 101 mph, Kopech is 3-0, 0.90 with 25 whiffs in 20 innings and just four walks.

Jose Siri, cf, Reds. Siri wasted no time extending his hit streak to 31 games with a first-inning homer against Lansingís Yennsy Diaz, and he added another in Daytonís 11-7 loss. Cincinnatiís No. 10 prospect has the coveted power/speed mix and is an excellent defender as well. During his streak, heís hitting .360 with 12 homers and 28 RBIs.

Erick Fedde, rhp, Nationals. The Natsí No. 2 prospect has been called up and will start Saturday in place of the injured Stephen Strasburg. Josh Norris has more.
