Andrew Cashner set aside nearly five months of struggles Wednesday night.
Kemp hit a fastball on a 2-2 count. He knew he'd hit the ball well, but wasn't sure he'd knocked it out.
"The ball travels well here,'' Kemp said. ''Good thing we were playing here.''
Kemp has 22 homers and 97 RBIs, most for a Padres' outfielder since Greg Vaughn had 119 in 1998.
Jarrod Saltalamacchia hit a solo homer off Cashner custom baseball jerseys cheap in the sixth to cut the Padres' lead to 4-3.
Craig Kimbrell got the final four outs for his 37th save. He also got his first career at-bat in the eighth, striking out. Kimbrell, who hadn't pitched in a week, had joked earlier in the day that he might get an extended stint on the mound and that he might actually step in the batter's box.
The result was an effective outing that was backed by Matt Kemp's three-run homer to help the San Diego Padres beat the Arizona Diamondbacks 4-3.
"Cashner was great; player of the game for custom baseball jerseys me,'' manager Pat Murphy said. ''He just attacked a very good offensive team...with 75 percent (of his pitches) or more were fastballs. Hopefully, he learned something cheap custom baseball jerseys he can take with him going forward, that custom jerseys baseball he doesn't need to go deep in counts. His fastball is that good.''
Cashner (6-15) allowed seven hits and three runs, striking out six and walking two, cheap baseball jerseys custom in seven innings. He had lost 13 of his previous 17 decisions since April 24.
''I haven't really gone deep into games lately,'' Cashner said. ''It was big to go deep. I commanded my fastball a lot better. I kept it down in the zone. I kept them off balance as far as inside and outside of the plate.''
Trailing 2-1 in the fifth inning, Wil Myers walked and then Yangervis Solarte singled. Kemp followed with a line drive to right that barely cleared the fence baseball jerseys custom to give the Padres a 4-2 lead and chase Robbie Ray (4-12) from the game.
