Arizona right-hander Drey Jameson held the San Diego Padres to two hits over seven scoreless innings in his major league debut on Thursday, leading the Diamondbacks to a 4-0 win in Phoenix.
Ketel Marte, Emmanuel Rivera and Carson Kelly hit solo homers for the Diamondbacks (68-75).
The 6-foot, 165-pound Jameson issued one walk and struck out five. He finished his outing by retiring the last nine Padres he faced after Brandon Drury opened the fifth with a double.
Jameson, 25, was drafted 34th overall by the Diamondbacks in 2019. The product of Ball State University was 5-12 with a 6.95 ERA with Triple-A Reno before being promoted for the Thursday start.
The Padres (78-66) took a second straight loss, reducing their lead over the idle Milwaukee Brewers (76-67) to 1 1/2 games in the race for the third National League wild-card berth.
San Diego finished with three hits on Thursday in its 10th shutout loss of the season. The Padres have scored only five runs in their past four games.
The game was scoreless until Marte led off the fourth against Padres starter Sean Manaea with his 11th homer of the season, a line drive into the seats in left-center. Manaea retired the next two batters on groundouts before Rivera hit his 12th home run down the line in left.
Manaea (7-9) gave up the two runs on three hits and no walks with three strikeouts in five innings.
Kelly’s seventh homer of the season came on a drive to left-center against Padres reliever Nick Martinez with one out in the seventh inning.
The Diamondbacks added a fourth run in the eighth. Padres reliever Steven Wilson hit leadoff man Stone Garrett with a pitch. Garrett moved to second on an errant pickoff throw, advanced to third on an infield hit by Jake McCarthy and scored on Christian Walker’s line-drive single to center off Luis Garcia.
Arizona reliever Kevin Ginkel, Joe Mantiply and Reyes Moronta combined on two scoreless innings to close out the win.
