Just as predictable, Matt Holliday has feasted on the pitching of his former team.Holliday looks to help the Cardinals sweep the three-game set with an eighth straight home win in Sunday's finale.St. Louis (82-67) entered this series on the heels of a three-game losing streak before winning 5-1 in Friday's opener. The Cardinals held on for a 5-4 victory the next night to move 3 1/2 games ahead of second-place Pittsburgh and five up on scuffling Milwaukee.Holliday hit a homer that traveled an estimated 467 feet Friday, then went deep again Saturday."He's one of the best hitters in the game," winning pitcher Shelby Miller said.Colorado (59-89) probably agrees with that sentiment.Holliday is 10 for 20 with five extra-base hits in five games against the Rockies this season, and batting .453 with eight homers, seven doubles and 27 RBIs in 19 contests against them since the start of the 2012 season.Holliday, who spent the first five years of his career with Colorado, went 2 for 3 with a double last July against starter Jordan Lyles (6-2, 4.20 ERA) in his lone start against St. Louis.The Cardinals have won 11 of 15 overall, and 12 in a row at home in the final month of the season dating to last Sept. 14. They're seeking their first single-season eight-game winning streak at Busch Stadium since July 2010.Michael Wacha was slated to take the mound for St. Louis on Sunday, but the right-hander is being pushed back for some extended rest. Rookie Marco Gonzales (2-2, 5.01) backed up Wacha in his two abbreviated starts since coming off the disabled list, and will get the ball from the get-go Sunday for his fifth big league start.Gonzales allowed a run over 2 1/3 innings in Milwaukee on Sept. 4 and pitched a scoreless inning Tuesday at Cincinnati.A first-round draft pick in 2013, the left-hander made his major league debut at Colorado on June 25, surrendering five runs and seven hits in five innings of a 9-6 win, though he did not factor in the decision. His ERA rose to 9.64 with another shaky outing six days later, but he's recorded a 1.69 ERA in his last two starts."He's doing a great job," manager Mike Matheny told MLB's official website. "That time we gave him an opportunity against Colorado, I thought he did a great job, too. Put him back in that position and see how he does."The Rockies were on the verge of another meager offensive showing Saturday before scoring three runs in the ninth. They had plated three runs in losing the first four contests of a six-game trip, and are averaging 1.5 runs while batting .177 in losing 10 of 11 on the road.Lyles owns a 2.90 ERA in his last seven road outings but a lack of run support has left him with a 1-1 record.The right-hander, who has one win in his last 11 starts, allowed a run and three hits in six innings in Monday's 3-2 loss to the New York Mets, but did not receive a decision. Although it was the first time he permitted less than two runs since April 30, Lyles wasn't particularly happy with the performance."Just physically I don't think I was there where I usually am, but we can't complain with a quality start," he said.
