On April 13, Finch pitched all 11 innings to grab a 3-0 win, plus slugged the game-winning three-run home run in the bottom of the 11th.
On April 14, she pitched the eighth and ninth innings for UA in a come-back 4-3 victory over the Sun Devils. She struck out three.
Finch now owns a 16-0 record with a Pac-10 best 0.35 ERA. She is also hitting .339 with 10 home runs on the season.
The Player of the Week honor is the fourth in Finch's career and the 70th all-time weekly honor for an Arizona player.
