Troy Tulowitzki hit a two-run homer in the eighth inning — a call changed after the umpires initially ruled fan interference — and the Colorado Rockies held on for a 5-4 victory Tuesday night that ended their streak of six consecutive losses to the Cincinnati Reds.
A fan with a glove in left field reached and grabbed Tulowitzki's fly ball off Sam LeCure (1-1). The umpires initially ruled fan interference, but changed the call and awarded Tulowitzki his 13th homer after reviewing video that showed the ball had cleared the wall.
The Reds took a 4-3 lead in the seventh on Edgmer Escalona's balk for a third-to-first pickoff fake — a play that was outlawed this season. 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.
NOTES: The Rockies sent starter Tyler Chatwood back to Denver for an MRI on his sore right triceps, which forced him from a 3-0 loss to the Reds on Monday night in the fifth inning. Chatwood is expected to miss at least his next turn. A medical exam was encouraging. ... Reds 2B Brandon Phillips missed a third straight game with a bruised left forearm. He took batting practice and said the arm felt better. He's expected back on Friday for the opening of a series against first-place St. Louis. ... Umpire Lance Barrett filled in for Kerwin Danley, who was hit on the facemask by a deflected pitch and left the game with a headache on Monday night. ... RHP Johnny Cueto (3-0) makes his fourth start since coming off the DL in the series finale on Wednesday. RHP Jon Garland (3-6) starts for the Rockies.
