Harvey, a 26-year-old right-hander, went 13-8 with a 2.71 earned-run average this season. He struck out 188 batters in 189 1/3 innings and walked only 37. This is his first full season coming off Tommy John surgery and, perhaps as a result of his sudden workload, his fastball velocity began declining gradually beginning in August.So, Harvey took some time off in September to rest his right arm. When he returned he threw his fastball a bit less often — it still averaged 95 mph — and Harvey allowed only two runs in his final three starts of the season.“We set this up a long time ago as you know coming into the series,” Mets manager Terry Collins said. “We had Matt in Game 3 because I thought it was going to be a pivotal game, which it is now going to be. So I think we have the right guy going. I think he’s handled it great. He’s fired up about it. You know, certainly there are no limits, obviously, outside of we’ll be very cautious of the pitch counts because he really hasn’t thrown a lot of pitches in the last month. But I think we have the right guy on the mound for us on Monday.”Anderson was not a shoo-in to pitch Game 3 to the same degree, though Dodgers manager Don Mattingly said there was no debate once the season ended. Anderson, 27, went 10-9 with a 3.69 ERA in his first full season since 2009.Only Clayton Kershaw and Zack Greinke made more starts for the Dodgers this season than Andreson’s 31. That’s a minor miracle considering Anderson had spent more time on disabled lists than active rosters from 2010-14. Newsroom GuidelinesNews TipsContact UsReport an Error By pitching 180 1/3 innings, Anderson earned himself more than $2 million in salary bonuses. Apart from some minor injuries, Anderson was healthy from start to finish, something the pitcher did not take for granted.But in a pivotal Game 3, with the winning team poised to take a 2-1 lead in the series, the last six months doesn’t matter very much. Anderson will be tasked with getting the Dodgers into a clinching situation for Game 4, in which Kershaw seems likely to take the ball on three days’ rest.Anderson, Kershaw said, is as steady as they come.“He really hasn’t changed a whole lot for me since we were 16,” said Kershaw, who has seen Anderson pitch since the two were high schoolers in Texas. “He might have had better overall stuff when he was 17 and 18, just on injuries and stuff, but he’s learned how to pitch a lot better.“For him,” Kershaw continued, “it was always a matter of health. I knew that coming in. He was going to make 30 starts for us and have a good year, he and he did.” Ask anyone to describe Brett Anderson’s demeanor — his teammates, his coaches, the men who decided to give him $10 million plus a bunch of incentives to pitch for the Dodgers this year — and the one word they usually agree on is “quiet.” It’s the kind of emotional makeup you would want for someone who will become the first visiting pitcher to start a playoff game at Citi Field on Monday. The New York Mets’ home park will not be quiet. Its capacity is listed at 45,000 for baseball, and Game 3 of the National League Division Series will be the first postseason baseball game it has hosted in six years of existence.The atmosphere, former Met and current Dodger Justin Turner said, “should be pretty electric.”Mets starter Matt Harvey should be, too.
