Beras has been on a power surge of late for Class A Advanced High Desert, having hit five home runs in his last 10 games entering Tuesday. The 21-year-old outfielder has swung a hot bat in 32 games since the All-Star break, posting a .266/.316/.532 batting line with nine home runs. For the season, Beras is hitting .249 with 17 home runs and 17 doubles through 83 games for the Mavericks.
Cotton is set to make his second start as a member of the A's after coming over from the Dodgers at the Trade Deadline along with Grant Holmes and Frankie Montas in the deal for Josh Reddick and Rich Hill. The 24-year-old right-hander picked up the win in his first turn for Triple-A Nashville on Aug. 4, when he allowed one earned run and fanned five in six innings. Cotton has yielded 18 home runs in 103 1/3 innings, resulting in a 4.70 ERA, but he's been otherwise solid, posting a 1.15 WHIP with 124 strikeouts and 33 walks in that span.
Newcomb, No. 56 on the Top 100, set a season high with 10 strikeouts and allowed one earned run on three hits over 6 2/3 innings in his last start for Double-A Mississippi, one of his better performances in 2016. The 23-year-old left-hander has piled up 17 strikeouts against three walks across his past two turns, giving him an overall strikeout-to-walk ratio of 118-60 through 112 innings (22 starts). He enters the day with a 5-7 record, 4.26 ERA and a .238 opponents' batting average.
Taylor has yet to suffer a loss in six starts since being promoted to Double-A Mobile, during which he's posted a 1.72 ERA and 0.90 WHIP over 36 2/3 innings. Before moving up to the Southern League, the 23-year-old southpaw struggled to the tune of a 5.65 ERA over 78 innings in the Class A Advanced California League, though he did record 77 strikeouts in that span.
