SOUTH BEND Jim Thome Jersey , Ind. (AP) — Chicago Cubs right-hander Yu Darvish lasted just one inning in his rehab start with Class A South Bend on Sunday, casting doubt on his availability for the rest of the year.Darvish, who has been sidelined by triceps and elbow injuries, shook his arm as he left the field after striking out Great Lakes’ Romer Cuadrado with a 95-mph fastball for the last out of the first. But he said the first inning was great.“I felt real good,” Darvish said through an interpreter. “I didn’t feel any abnormalities in that sense.”When Darvish warmed up for the second, he threw six pitches and winced on each one. Miguel Amaya, who caught Darvish’s rehab start for South Bend on June 25, walked to the mound and summoned manager Jimmy Gonzalez and a trainer. After a short discussion, Darvish walked to the dugout.“During warmups the next inning, I felt something in there,” Darvish said. “Last time (in June) I did feel the same thing (but) I continued to throw. This time I stopped.”Darvish, who turned 32 on Thursday, signed a $126 million, six-year contract with Chicago in February. But he has made just eight starts in his first year with the Cubs, going 1-3 with a 4.95 ERA.Darvish said he would ask for an MRI when he got back to Chicago. He wasn’t sure if would miss the rest of the year.“I can’t really tell right now,” Darvish said. “It depends how I feel tomorrow. I really want to come back this season. I am going to work hard and do my best to try and come back.”The Cubs are on top of the NL with a 71-52 record http://www.philliesfanproshop.com/authentic-scott-kingery-jersey , but their rotation is looking a little thin. Mike Montgomery was placed on the 10-day disabled list on Friday with left shoulder inflammation, and Tyler Chatwood has struggled in his first year with Chicago after signing a $38 million, three-year contract over the winter.The Cubs were optimistic about a possible return for Darvish after he threw about 55 pitches in a simulated game on Tuesday. But that optimism was likely wiped out by Sunday’s rehab appearance.Darvish allowed a first-pitch single and issued a walk, then retired three in a row. He totaled 19 pitches, 10 for strikes.In his June rehab start for South Bend, Darvish allowed one run and three hits in five innings. His fastball reached 94 mph, but he complained afterward that his arm got tired as the outing went on. DENVER — Left-hander Kyle Freeland, the most consistent Colorado starter, will take the mound Thursday as the Rockies attempt to win their four-game series with the Arizona Diamondbacks.Colorado second baseman DJ LeMahieu belted a two-run homer with one out in the ninth Wednesday — his first career walk-off hit — to give the Rockies a 5-4 victory, their second in this series.The Rockies (80-65) lead the National League West by 1 1/2 games over the Los Angeles Dodgers and 3 1/2 over the Diamondbacks. Arizona (77-69), losers of nine of its past 12 games, is four games back in the scramble for the second NL wild-card spot.Article continues below ...The Rockies, winners of eight of their past 11 games, are 20-9 in games started by Freeland (14-7, 2.91 ERA), who will be opposed by Clay Buchholz (7-2 Odubel Herrera Jersey , 2.01) — a vital addition since joining the Arizona rotation in late May. He will be making his Coors Field debut.Freeland has been dominant there this season, going 8-2 with a 2.21 ERA in 13 starts. Freeland is 5-0, 2.03 in his past seven turns, all of which the Rockies have won.Freeland, a 25-year-old Denver native in his second full season in the majors, is 0-1 with a 4.96 ERA in three starts this season against the Diamondbacks, the last July 21, and 1-2, 4.60 against them in six career starts.“Kyle’s game stays pretty consistent,” Rockies manager Bud Black said. “Command of the fastball (to) both sides of the plate. When he goes in, I think he’s got to elevate it a little bit with the fastball — belt high to the hands. Down and away with the fastball. The slider down underneath the right-handed swing. Mix in the change, keep them off balance with the change of velocities with the changeup. Preferably down and away with some action, which he’s very capable (of doing). Mix in a couple curveballs, which Kyle’s done a really good job this year of bringing that into his game. “Kyle’s game has become pretty consistent. It’s something Kyle should be proud of, the step that he made last year to where we are now.”Buchholz, 34 http://www.philliesfanproshop.com/authentic-jorge-alfaro-jersey , unable to find a big league job after last season, signed a minor league deal with Kansas City. He went 1-0, 1.59 with the Royals’ Triple-A Omaha affiliate and excercised the May 1 opt-out date in his contract and signed a minor league deal with the Diamondbacks.Arizona general manager Mike Hazen and several of his assistants were in the Red Sox front office when Buchholz signed with Boston after being drafted in the first round in 2005, and Arizona manager Torey Lovullo was a Boston coach when Buchholz pitched for the Red Sox.Buchholz threw a no-hitter Sept. 1, 2007, in his second major league start, went 17-7 with a 2.33 ERA in 2010 and made the Amerian League All-Star team. He was an all-star again in 2013 before enduring a succession of injuries.Buchholz made three minor league starts for the Diamondbacks before joining their rotation May 20. He missed a month with a left oblique strain but returned to the rotation July 24 and has gone 5-1, 1.66 in his past nine starts.Asked whether it’s more rewarding to be pitching as well as he has now as opposed to the outset of his career, Buchholz said, “Yeah, probably just for the simple fact that there were a lot of people that wrote me off, and I wasn’t ready to be done playing.”Said Hazen: “He’s been healthy, and I think you’re seeing the true pitcher emerge. He’s not the guy he used to be with pitches that everyone oohed and awed over at the time. Now you’re watching this guy really pitch. It’s fun to watch. He’s obviously shot above and beyond anything we could’ve hoped. I give a lot of credit to him. He’s one of the leaders of our clubhouse, and you just see the maturity every day with him.”Buchholz’s one career start against Colorado came in 2016, when he allowed six runs in five innings and took the loss.
