Home run? Double? Who knew? Not Troy Tulowitzki .
The Rockies shortstop was running all-out when a fan grabbed his fly ball by the top of the wall in left field. The umpires initially ruled the fan had reached over the wall and awarded Tulowitzki a double. One minute later, they changed their minds.
Tulowitzki wound up with a two-run homer in the eighth inning, and the Rockies held on for a 5-4 victory Tuesday night that ended their streak of six consecutive losses to the Cincinnati Reds .
"I didn't really see him touch it," Tulowitzki said. "I was just running and wanted to make sure I made it to second base."
The umpires needed only a minute to watch the video and see that the fan with a glove had caught the ball above the top of the wall. They overturned the initial fan-interference call and awarded Tulowitzki his 13th homer.
"A big-time home run by a big-time player," Colorado manager Walt Weiss said. "It doesn't get any more clutch than that."
Sam LeCure (1-1) retired the first two Rockies in the eighth before walking Carlos Gonzalez and going to a full count on Tulowitzki, who got the fastball he was expecting.
Reds manager Dusty Baker went with LeCure instead of Jonathan Broxton in the eighth because he was already warming up and has pitched well lately. LeCure hadn't allowed a run since May 5.
"As a reliever, the later you're in the game, the better," LeCure said. "Today just wasn't my day. I've been throwing the ball well, and people kept reminding me of that, and I kept saying, `Someday, it's going to end.' It didn't have to be today."
Nobody was happier about the homer than reliever Edgmer Escalona , whose mental lapse gave the Reds a go-ahead run in the seventh. Escalona tried the third-to-first pickoff fake that was outlawed this season, resulting in a balk that gave the Reds a 4-3 lead.
"I figured at some point this year, somebody was going to do that with the new rule," Weiss said.
Josh Outman (2-0) fanned Joey Votto and Jay Bruce to end that rally. Rex Brothers pitched a perfect ninth for his second save. The left-hander is filling in as closer with Rafael Betancourt sidelined by a strained groin.
The Rockies are 2-6 against the Reds over the last two seasons.
Colorado pulled ahead 3-0 against Homer Bailey , but couldn't hold on. Juan Nicasio gave up three runs in six innings, with Ryan Hanigan driving in a pair.
Bailey was coming off his worst start of the year. He lasted a season-low 3 2-3 innings during a 7-1 loss in Cleveland on Thursday, when he gave up seven runs with two outs in the fourth.
The right-hander had another bad inning against the Rockies, who scored three times in the second. Jonathan Herrera doubled home two runs, and Dexter Fowler singled home another run with two outs. Bailey then settled in, retiring the next 13 batters.
Todd Frazier led the Reds' comeback. He extended his hitting streak to five games with a double in the second and scored on Hanigan's groundout. Frazier doubled again, driving home a run in the fourth, and came around on Hanigan's double to tie it 3-all.
Frazier, who finished third in NL Rookie of the Year voting last season, has pulled out of his slow start by batting .352 in his last 16 games.
Michael Cuddyer singled and scored the Rockies' first run, extending his hitting streak to eight games. Herrera finished with three hits.
