DENVER -- The Colorado Rockies watched a four-run lead dissolve in the seventh inning Tuesday night. They saw closer Rafael Betancourt walk off the mound after throwing two pitches in the 10th.
But they overcame these disheartening situations and salvaged a 5-4 victory over the Arizona Diamondbacks in 10 innings on a single by Wilin Rosario.
Former Rockies left-hander Matt Reynolds took the mound for Arizona in the 10th. With one out, Carlos Gonzalez doubled and, after Troy Tulowitzki was intentionally walked, Rosario smacked a single to right field to win the game.
Betancourt, who has a 1.56 ERA in 18 games and has converted his 10 save opportunities, came into the game and threw two pitches in the dirt to Paul Goldschmidt. On the second one, Betancourt spun off the mound toward first base. With manager Walt Weiss, pitching coach Jim Wright and head trainer Keith Dugger watching, Betancourt threw several pitches and then left the game.
Rockies starter Jhoulys Chacin sailed through six scoreless innings, holding the Diamondbacks to one hit, a two-out double in the third by pitcher Ian Kennedy. But the Diamondbacks struck for four runs in the seventh, chasing Chacin after 6 1/3 innings.
Two walks by Chacin and an error by first baseman Jordan Pacheco set up the rally. Chacin walked Goldschmidt with one out and found himself with runners on first and third when Pacheco muffed Eric Chavez's grounder. Chacin walked Cody Ross to load the bases.
Jason Kubel drove in two runs with a double to left-center on a 0-2 fastball, the ball just eluding diving left fielder Gonzalez. Martin Prado then tied the game at 4-4 when he grounded Chacin's 1-1 slider up the middle. Chacin had held the Diamondbacks scoreless for 20 1/3 innings before the fateful seventh.
Left-hander Josh Outman relieved Chacin and gave up a single to Miguel Montero, the ball falling into right field in front of Charlie Blackmon. Outman walked pinch hitter Josh Wilson to load the bases but struck out Gerardo Parra and Didi Gregorius on called third strikes. Both players briefly voiced their displeasure with home plate umpire Adrian Johnson on his calls.
The Diamondbacks' seventh wiped out an early lead the Rockies had built. Tulowitzki hit his ninth homer in the third and scored the first of two runs in the second when Nolan Arenado and DJ LeManhieu, who went 3-for-4 with two doubles and two RBI, hit back-to-back two-strike singles with one out. Tulowitzki's homer broke the Diamondbacks' streak of six straight games without allowing a home run, which tied a club record.
The Rockies added an unearned run in the fourth when shortstop Gregorius' high throw enabled Arenado to reach base, and he scored on LeMahieu's double to left. Arenado just beat Gregorius' strong relay throw.
Chacin was trying to take care of some unfinished business against Arizona. He last started against them here on April 19 and limited them to three hits in 6 1/3 scoreless innings but left after throwing his 100th pitch with a back strain that put him on the 15-day disabled list and caused him to miss two starts. He returned May 5 and went 0-3 in three starts with a 7.79 ERA before this outing.
In six previous starts at Coors Field, including a loss April 19 in a matchup with Chacin, Kennedy had gone 1-2 with a 3.41 ERA, which was the second lowest ERA there among active starters with a minimum of 30 innings. That figure rose to 3.53, which is still second lowest.
NOTES: RF Blackmon made his fifth start for Colorado and batted second for the first time. Manager Walt Weiss said, "Charlie runs well. He's a guy you can hit-and-run with, a guy that can hit the hole at first base with a man on first and hit the ball in the gap. There's been a couple other times I thought about hitting him in the two hole. Today, I actually put it on paper." Blackmon had batted eighth in each of his previous four starts. ... 1B Todd Helton was not in the Rockies' lineup. He typically doesn't play in a day game after a night game but will play Wednesday afternoon against Diamondbacks RHP Trevor Cahill. Weiss said Cahill's heavy sinker makes him tough on right-handed hitters, so he opted to start Jordan Pacheco on Tuesday night and play Helton on Wednesday. ... Rockies RF Michael Cuddyer (inflammed cervical disc) played in an extended spring training game in Scottsdale, Ariz. "I think he got five at-bats and all went well," Weiss said, adding he wasn't concerned with the specifics and was more interested to learn "that physically he got through it well." Cuddyer is scheduled to play another extended spring training game Wednesday. Barring a setback, he will be activated Friday in San Francisco when he is eligible to come off the 15-day disabled list. ... Rockies LHP Jorge De La Rosa will start Wednesday almost two years to the day he tore the ulnar collateral ligament in his left elbow pitching against the Diamondbacks at Coors Field on May 24, 2011. "It's one of the tough days in my career," De La Rosa said. "It was a long rehab. I'm glad I'm ready to go; I think I'm helping the team a little bit." That's an understatement, since De La Rosa is 5-3 with a 3.58 ERA in nine starts, six of which the Rockies have won. ... LHP Jeff Francis (left groin strain) threw a touch-and-feel bullpen session, his first since he was injured May 14. Trainer Keith Dugger said Francis started throwing on the slope but then moved to the mound because he was feeling so good and threw 25 pitches. ... Diamondbacks manager Kirk Gibson said Ian Kennedy and Cahill are likely to pitch the doubleheader on Monday against the Texas Rangers. "That's what we're thinking of doing right now," Gibson said. "It could change." Because the Diamondbacks have an off day Thursday, Kennedy would pitch Monday with one additional day of rest and Cahill would be on regular rest. ... Gibson said there is no timetable on OF Adam Eaton (strained left elbow), who through Monday had played 16 rehab games with high Class A Visalia and Class AAA Reno. ... Gibson said 2B Aaron Hill (broken left hand), who is rehabilitating at the Diamondbacks' complex in Scottsdale, Ariz., will see a doctor in the next week, which will be two weeks after he last was examined. Gibson said the plan is, after this examination, Hill can begin strengthening exercises. ... The Diamondbacks entered Tuesday having not allowed a home run in six straight games, tying a club record set Aug. 8-13, 2001, and matched Sept. 23-27, 2004. ... Patrick Corbin, who gave up three hits and had 10 strikeouts Monday, became the third visiting pitcher at Coors Field to throw a nine-inning complete game with at least 10 strikeouts. The others were Montreal's Pedro Martinez on July 29, 1997, and San Diego's Kevin Brown on July 15, 1998.
