Haren makes his final regular-season start looking to continue his recent dominance at home Saturday night against the Colorado Rockies.Haren (13-11, 4.03 ERA) is concluding his first season with Los Angeles (92-68) and he can decide to return in 2015 after reaching 180 innings activated a player option at $10.5 million, according to MLB's official website.He earned a chance at a second year with the Dodgers after allowing two runs and one hit with seven strikeouts in seven innings of Monday's 5-2 win in 13 over San Francisco.Despite the effort, Haren said qualifying for the option was weighing on him."Of course I think about it," Haren told MLB's official website. "I may say I'm not, but there's a number set there by them, and I feel like I pitched pretty decent the whole year. Whether I earned it or deserve it, that's kind of up to someone else's opinion. I think what I have earned is the right to choose if I want to come back. ... I think I've pitched good enough to deserve that."Haren may also deserve a spot in the Dodgers' postseason rotation."I would love to have one more good start and have three good starts in the playoffs, and I'd feel really good," Haren said.The right-hander has had four outstanding starts at home lately, going 3-0 with a 1.00 ERA. However, he owns an 11.57 ERA during a four-start losing streak to the Rockies, but only one was at home and none were in Los Angeles.Haren surrendered five runs in five innings of a 10-4 defeat to them Sept. 16.The Dodgers' offense hasn't had any such issues with Colorado of late, hitting .331 and outscoring the NL West rival 25-7 while winning four straight home matchups.They scored six runs in the sixth to beat the Rockies 7-4 in Friday's series opener.Dee Gordon has a .419 average against Colorado (66-94) this year after doubling on two of his three hits Friday, snapping an 0-for-14 slump over the previous three contests.The All-Star second baseman leads the majors with 64 stolen bases, and he could become the first Dodger to reach 65 since Davey Lopes had 77 in 1975.Justin Morneau continues to be a bright spot for the Rockies, as he chases the NL batting crown. He went 2 for 3 with a two-run homer Friday, giving him a league-leading .319 average, one point ahead of Pittsburgh's Josh Harrison."It's very cool to see the season Morney's put together," manager Walt Weiss said. "He's one of the guys you pull extra hard for."While Morneau is bidding to give Colorado back-to-back batting champions after Michael Cuddyer last year, Eddie Butler (1-1, 5.56) is looking to give the club a glimpse of its future.That didn't go well the last time the 23-year-old right-hander faced the Dodgers on June 6 in his major league debut. He was tagged for six runs and 10 hits with three walks in 5 1/3 innings of a 7-2 loss.Butler landed on the disabled list three days later with rotator cuff inflammation, but was impressive in his return last Saturday. He allowed one run in six innings of a 5-1 win over Arizona.
The Colorado Rockies have slugged a MLB-high .463 in at-bats to end in a slider from a right-handed pitcher; the next closest team is slugging .401 in such ABs. Dan Haren has thrown the second-highest percentage of sliders among qualified right-handed pitchers this season (35.8 percent).
