CHICAGO -- Each start was remarkably similar. That smooth, efficient motion. The devastating array of pitches. The easy cool that quickly spreads to his teammates, who are so confident when he takes the mound. A year after a disappointing departure from Baltimore, Jake Arrieta is thriving in Chicago. The 6-foot-4 right-hander is unbeaten in his last eight starts after beginning the season on the disabled list due to shoulder tightness, providing a glimmer of hope as the lowly Cubs stumbled to last place in the NL Central at the All-Star break. "Jake knows it now, hes our new horse and thats what we want," first baseman Anthony Rizzo said. "We want him to be that ace and just keep getting all the confidence in the world because hes pitching very confident right now and its been fun to watch." Arrietas undefeated stretch began with one of his shortest outings of the season, when he lasted just 4 2-3 innings on June 3 against the New York Mets. He gave up seven hits and walked three, but he allowed just one first-inning run in Chicagos 2-1 victory. Then he really put on a show. Arrieta pitched six shutout innings against Miami, and seven more against Philadelphia. He retired his first 18 batters in a victory over Cincinnati. He was so good against the Red Sox that the fans at Fenway Park saluted him with a loud ovation when he departed after Bostons first hit with two out in the eighth. Heading into Sundays start at Arizona, Arrieta is 4-0 with a 1.36 ERA and a .160 opponents batting average during his impressive six-week run. "Hes got a good slider and hes got a very deceptive way that he comes at you," Reds All-Star catcher Devin Mesoraco said. "Its really cross-bodied and its almost like hes throwing from behind you, so its a heck of an angle to try to hit the ball from, especially for a right-hander." Arrietas repertoire includes a fastball that sits in the low 90s, a big curveball and a circle changeup that he mixes in to prevent hitters from sitting on his fastball. But its that slider and his ability to use it as a cut fastball that has been particularly effective. "Its a cutter and a slider depending on what I want it to be," he said, before running through how he uses it in different situations. "Its one pitch, but I can throw it multiple different ways at different velocities." Arrieta was selected by the Orioles in the fifth round of the 2007 draft out of TCU. He made his major league debut three years later at age 24, and won 10 games the following season. He drew Baltimores opening-day start in 2012, and threw seven scoreless innings in a victory over Minnesota on the 20th anniversary of the opening of Camden Yards. It looked as if he could be a key contributor for the Orioles for years to come, but that was really the beginning of the end when it came to his time in Baltimore. Arrieta shuffled back and forth between Triple-A Norfolk and Baltimore before he was traded to Chicago last July. The contending Orioles also sent reliever Pedro Strop to the Cubs in return for pitcher Scott Feldman and catcher Steve Clevenger. "I was bombarded by information from 50 different sources, which is never beneficial to anybody, I dont care who you are," Arrieta said, reflecting on his departure from the Orioles. "You got four or five different sports psychologists trying to reach out to you, you got seven different coaches trying to implement some input, you know that never works. It just kind of made things go in the opposite direction." Arrieta credits the change of scenery and his experience in developing a successful routine as two big reasons for his recent success. He also has a solid relationship with pitching coach Chris Bosio, who has become quite the asset for the Cubs when it comes to turning around cheap reclamation projects. Next up for Arrieta is just building on his solid first part of the season. Chicago traded Jeff Samardzija and Jason Hammel to Oakland on July, making Arrietas starts even more important for the Cubs for the rest of the year. They believe he is up to the challenge of anchoring the staff. "I think when he goes out there on the hill, hes got a calmness about him," manager Rick Renteria said. "Hes got some poise and hopefully this is now a turning point, it continues to be a turning point for him in his career and he continues to move forward and hes able to take advantage of that great stuff hes got."

Louis, MO (SportsNetwork.PORT LUCIE, Fla. -- New York Mets closer Bobby Parnell threw batting practice Saturday, facing batters for the first time since his 2013 season was cut short by a neck injury. Parnell last pitched in a game on July 30. He missed the final two months of the season and had surgery Sept. 10 to repair a herniated disc in his neck. The right-hander threw 36 pitches to David Wright, Daniel Murphy and Eric Young Jr. "You work all off-season throwing bullpens with no batters in there and it seems like you cant miss a spot," Parnell said. "You throw a hitter in there and it becomes 100 times harder. It feels good to get out there and face some guys, face some hitters and find the strike zone with some intensity turned up. It waas a nice feeling today.dddddddddddd" Parnell said he was able to keep the ball down and didnt feel any discomfort in his neck or right arm. "Ive been taking a lot of baby steps," he said. "I feel great, my arm feels good, neck feels good. Everythings going well. But as far as today, this feels like a big mental hurdle. I didnt know how I would react to balls coming off the bat and I felt strong out there. I felt good and felt like I had some reaction in the neck, so everythings good." The Mets are being cautious with Parnell, but he is currently scheduled to throw a second batting practice on Tuesday. He said hell throw at least one more batting practice session before getting into a game. ' ' '
