It shouldn't come as much of a surprise, but no team in the Majors has scored as many runs in its home park as the Colorado Rockies, who have plated 174 runs in 32 games (5.4 runs per game).
Coors Field has been a 10th man for the Rockies, who enter Saturday's game against the Padres in the middle of a 10-game homestand. They're 19-13 at home this season, with a 13-5 record at home against National League West opponents. And they are 7-1 against the Padres.
Padres lefty Eric Stults, who has a 2.64 ERA over his last seven starts, having allowed two runs or less in five of them, will try to contain a potent Rockies offense. In 30 games (26 starts) since joining the Padres last season, Stults is 12-8 with a 3.29 ERA (61 ER, 167.0 IP).
He's given the Padres valuable innings this season, working at least seven innings in three of his past four starts.
"I'm a contact guy, so if I could keep my pitch count low early, that helps me work deep into the game," he said.
The Rockies will counter with Jeff Francis, who was activated off the disabled list after dealing with a left groin strain. Through eight starts this season -- the most recent a six-inning, one-run outing against the Cubs on May 14 -- the left-hander is 2-3 with a 6.00 ERA.
Rockies: Missing CarGo
• Carlos Gonzalez did a lot of running Friday night, racing from home to third on a pair of RBI triples. But it was an at-bat in the sixth inning that caused him to turn his ankle and eventually forced him to exit the game.
Gonzalez, who hit three homers Wednesday, has been a force in the middle of the Rockies' lineup this season. He's second in the NL with 17 homers, driving in 45 runs and scoring 51.
&$149; Rockies outfielder Michael Cuddyer has a 10-game hitting streak. Cuddyer wasn't in Friday's lineup while dealing with soreness after tumbling across first base in the 12th inning of Thursday's game. He's expected to be back in the lineup Saturday.
Padres: Grim news for Alonso
First baseman Yonder Alonso received some bad news this week, when a CT scan revealed a fracture of the metacarpal in his right hand. Alonso is expected to miss at least four weeks.
"It was pretty painful," Alonso said Friday. "It's good news I was able to swing a bat in the first place. I'm shooting for three weeks, and I've already missed one week."
Alonso hadn't played since May 31, but he was playing well for the Padres, hitting .284 with six homers and 29 RBIs in 54 games.
Jesus Guzman and Kyle Blanks will fill in at first. Blanks went 3-for-5 with a homer and three RBIs in Friday's 10-9 loss.
• The Padres' 55 steals lead the Majors. Everth Cabrera leads all players with 26.
• Nolan Arenado hit his fifth homer in the ninth inning Friday night to win the game for the Rockies. It was his first career walk-off hit and the fifth walk-off win for the Rockies this season.
