PHOENIX_Tyson Ross' trade value appears to have plummeted even further than the San Diego Padres' offense.
The right-hander on Saturday night gave up eight runs in two innings to the Arizona Diamondbacks, who would score more runs than they ever had in a single game in a 20-5 rout of the Padres.
Padres outfielder Wil Myers hit three home runs, the first time he hit three in a game and the ninth time a Padres player has done so.
Christian Villanueva helped the Padres beat the Rockies with three homers on April 3.
Myers, who would also hit solo homers in the third and seventh innings, put the Padres up 2-0 in Saturday's first inning.
That lead disappeared quickly.
By the time Ross (5-7) was lifted after the second inning, it was 8-2.
He has allowed at least one run in five straight innings going back to the fourth inning of last Sunday's loss to the Pirates. Ross left that 7-5 loss after giving up a solo homer to lead off the sixth inning.
Ross had a 3.32 ERA (over 95 innings) entering that game. His ERA in the past two starts is 19.29 (in seven innings).
Ross' name surfaced as a trade possibility early, as the 31-year-old right-hander began the season with seven quality starts in his first 10 outings. That included his flirtation with a no-hitter here on April 20, when he did not allow a hit until there were two outs in the eighth inning.
Kazuhisa Makita replaced Ross in the third inning Saturday and on his first pitch allowed a home run to Nick Ahmed. The Diamondbacks would score twice more that inning and add four runs in the fourth. It was the first time they scored three or more runs in each of the first four innings of a game in their 20-plus seasons.
The Diamondbacks would add a run in the sixth, three in the seventh and another in the eighth, giving them runs in all but one inning and breaking the team record set in an 18-7 victory over the Dodgers on May 18, 2014.
