Prospects Olson, Nunez put power on display

Matt Olson and Renato Nunez, the A's Nos. 5 and 6 prospects, combined for three home runs Wednesday, to lead Class A Advanced Stockton to a 10-2 victory at Lancaster. It was the Ports' ninth straight victory.

Olson and Nunez hit back-to-back, two-out home runs off Lancaster left-hander Kent Emanuel in the second inning. Nunez added another homer in the ninth inning off right-hander Patrick Christiansen.

Olson's home run was his 20th home run of the season and he added a walk, two runs and two RBIs. Nunez finished the game 4-for-4 with two home runs, a walk, two runs and three RBIs.

Olson leads the California League in home runs and ranks fifth among all Minor Leaguers. He is hitting .249/.399/.524 in 75 games this season.

For Nunez, Wednesday was his first two-homer game of the season and the second of his career. It came a day after the Venezuelan native was named to the World roster for the All-Star Futures Game, which will be played on July 13 at Target Field.

Nunez is hitting .285/.351/.530 with 14 home runs in 67 games this season. He is tied for fifth in the California League in home runs.
