ATLANTA -- An unexpected string of four consecutive starts has helped Gerald Laird find his swing.
As a result, the veteran backup catcher is helping the Braves stretch their lead in the NL East.
Laird drove in two runs with two hits, including a tiebreaking single in the eighth, and Atlanta beat Colorado 3-2 on Friday night after the Rockies lost third baseman Nolan Arenado to a broken finger.
Arenado left the game in the second inning after fracturing his left middle finger on a head-first slide into second base. Rockies manager Walt Weiss said he didn't know details of the injury, including if Arenado will need surgery.
Arenado appears bound for the disabled list.
"He'll miss some time," Weiss said. "It's tough news for our club. He's off to a great start and a hell of a player."
Laird, 34, earned the four straight starts as Evan Gattis was held out with viral symptoms. Laird went 5 for 15 with three RBIs in the four games.
"He's supposed to be a guy that's going to fill in once a week, twice a week," Braves manager Fredi Gonzalez said. "He's played four days in a row and he's come up big."
Laird said the regular playing time has helped him feel more comfortable at the plate.
"I felt like the last week or so I've taken better swings," he said. "Tonight I got some pitches up and was able to take advantage of it."
Laird said he knows his role is to play behind Gattis but added "I'm ready to go every day, four, five, six, seven in a row, I'll do it."
Michael Cuddyer hit a home run for Colorado.
Braves third baseman Chris Johnson was pulled from the game by Gonzalez in the second. Johnson said he lost his temper in the tunnel after striking out. Johnson, who has a history of similar incidents, said he apologized to the team.
Ramiro Pena, who replaced Johnson, led off the eighth with a double to the center field wall off Adam Ottavino (0-1). After Andrelton Simmons and Dan Uggla struck out, Laird lined the single to left field and advanced to second when Corey Dickerson's throw bounced past catcher Jordan Pacheco.
Ottavino said Laird hit a slider.
"I threw a hittable one and he hit it," Ottavino said. "He did a good job. He committed to it and got the barrel on it."
Arenado led off the second with a double to left field. Left fielder Justin Upton's throw was caught by Uggla, who flipped the ball to shortstop Simmons at second base. Simmons kept the glove down as Arenado slid past the bag.
Gonzalez asked for a review as replays indicated Simmons might have tagged Arenado's foot off the bag. The play stood following the review of 3 minutes, 48 seconds.
Arenado grabbed his hand following the slide but remained in the game to score from third on Pacheco's groundout. Charlie Culberson replaced Arenado at third base in the bottom of the inning.
The loss of Arenado for a significant period would be a blow to the Rockies. Arenado is hitting .305 with six homers and 28 RBIs. His 28-game hitting streak from April 9-May 8 is the longest in the National League this season.
Uggla walked and scored on Laird's double in the second. The Braves took a 2-1 lead in the third. B.J. Upton scored from third base on Justin Upton's groundout.
Cuddyer's homer, his fourth, tied the game in the sixth.
Javy Lopez, a catcher for Atlanta from 1992-2003, Dave Pursley, a longtime trainer with Milwaukee and Atlanta from 1962-2001, and Rabbit Maranville, a shortstop with the Boston Braves for 15 seasons, were inducted into the Braves Hall of Fame. .... Weiss said OF Carlos Gonzalez (swollen left index finger), who didn't start for the second straight day, was available. Gonzalez aggravated the inflammation in the finger on Wednesday night. ... Braves LHP Mike Minor will face Rockies RHP Juan Nicasio on Saturday.
