Another week, another slew of exciting big league callups for top prospects. From MLB Pipeline's Top 100 Prospects list alone, we saw the Pirates’ Ke’Bryan Hayes, Miami's Jazz Chisholm, and the Yankees’ Deivi García and Clarke Schmidt make their Major League debuts.

They join an ever-growing rookie class in 2020 that includes current and former Top 100 prospects, players on their team’s Top 30 lists and those who were not ranked but are still making an impact.

Who turned in the best performance this past week, from Aug. 31-Sept. 6? Let’s take a look.

1) Randy Arozarena, OF, Rays
Arozarena went 7-for-14 last week for a .500/.563/1.143 line over five games. He went deep three times, highlighted by a two-homer, three-hit game on Sunday. He drove in a pair in that game against the Marlins and added two RBIs and a homer against the Yankees last Wednesday. The Rays went 4-2 during the week and now have a 5 1/2-game lead over the Blue Jays atop the American League East. Keep looking for Arozarena -- who hit third in the Rays lineup on Sunday -- to get at-bats.

2) Devin Williams, RHP, Brewers
What Williams has done this year has been absolutely insane, with the past week (4 2/3 IP, 0 H, 0 R, 1 BB, 10 K) in line with what the reliever has done all season. He’s given up one earned run on four hits over 17 innings (an opponents' batting average of .070), walking six and striking out 35. His other-worldly changeup is unhittable. Opponents are 0-for-39 with 26 strikeouts against what might be the best secondary offering in baseball right now.
