"I've been really working for two months, strengthening and really working hard," Chacin said. "I've been pain-free and throwing long-toss every day. Today was a really good day for me -- long-toss, flat ground and off the mound. I'm really happy."
Chacin hopes to be healthy enough to be a game-changer next season. He went 14-10 with a 3.47 ERA last year and was expected to lead the staff along with lefty Jorge De La Rosa. But Chacin showed up in Spring Training with a right shoulder strain, didn't pitch in a Major League game until May 4 and was 1-7 with a 5.40 ERA in 11 starts before he and the club decided to try again next year.
Chacin is not sure when he'll make his first start for Caracas in the Venezuelan Winter League. He'll need continued bullpen sessions and simulated games, at a place to be determined, before then. But Chacin is enthusiastic about gearing up for what will be a huge 2015 season.
This will be the final offseason of arbitration for Chacin, who is at the end of a two-year, $6.5 million deal. After next year, he's eligible for free agency for the first time.
"I want to get healthy and be the guy I was before, so I really don't worry about the contract," Chacin said. "I was worried before, especially when my arm was hurting. But now I'm calm, and I am going step by step. I'll get some innings this winter, after I'm 100 percent.
De La Rosa, a friend as well as colleague, signed a two-year, $25 million contract recently.
"I was talking to him [De La Rosa] and he always said, 'I really miss you; when we got together in the past, it was a really good year,'" Chacin said. "I know what I can do when my arm feels fine. I'll definitely be ready for Spring Training."
