Back in Spring Training, Brian Flynn hoped he would receive this opportunity. He was invited to big league camp, and thought this could be the season that he pitched on a Major League mound.
On Tuesday, Flynn joined Miami as one of four Minor Leaguers the Marlins called up. On Wednesday, Flynn will get the chance he's anticipated since February: The left-hander will make his first Major League start against the Cubs.
"I was really hoping to make it happen this year and get my feet wet at the end of the season," Flynn said.
Flynn spent time earlier this season pitching for Double-A Jacksonville, but spent most of the season with Triple-A New Orleans. In 23 Triple-A starts, Flynn went 6-11 with a 2.80 ERA. He had 122 strikeouts and 40 walks in 138 innings.
Miami manager Mike Redmond said he wants to see the 23-year-old enjoy his debut.
"You want a guy to go out there and just relax and pitch his game, throw strikes, and pound the strike zone and give himself a chance to win a ballgame," Redmond said. "I think that's what we all want."
Making the opportunity even sweeter for Flynn is that it's coming on the mound at Wrigley Field.
"It's a great ballpark, a historic ballpark and I'm a real big fan of baseball, so it's one of those things that I couldn't ask for more," Flynn said.
While Flynn will be throwing his first Major League innings on Wednesday, Cubs starter Jeff Samardzija is looking to eclipse 200 innings in a season for the first time in his career.
He's already pitched 183 this season, a career high, and a solid outing against the Marlins would help him reach the milestone. Samardzija threw 174 2/3 innings last season.
"It's a goal of all of [the starting pitchers] when the season starts," Cubs manager Dale Sveum said. "It's a measuring stick that you did your job and you went deep enough in enough games to get 200 innings and help the bullpen out and do things on a fairly consistent basis."
Cubs: Rosscup makes Major League debut
On the same day he was promoted from Triple-A Iowa, Zach Rosscup made his Major League debut and gave the Cubs some important outs in their 6-2 loss to the Marlins on Tuesday night.
With Chicago down one run in the top of the sixth and Juan Pierre on first base, Sveum brought in Rosscup to get the Cubs out of the inning. With Chris Coghlan at the plate, Pierre stole second base. But Rosscup struck out Coghlan for the second out of the inning.
With Donovan Solano batting, Pierre stole third. Rosscup walked Solano, but got the red-hot Christian Yelich to fly out to left field to end the inning.
Rosscup spent most of this season with Double-A Tennessee, where he struck out 66 batters in 43 1/3 innings. He was promoted to Iowa in August. The 25-year-old pitched in nine Triple-A games, allowing five runs over 7 2/3 scoreless innings.
Despite his impressive numbers, Rosscup wasn't necessarily expecting a callup to the big leagues.
"It was a surprise, for sure," Rosscup said of the promotion. "They've given me a lot of opportunities this year."
Marlins: Coghlan makes first start at third base
Coghlan started at third base for the first time in his Major League career in Tuesday's game. In the third, he saved a run with a diving grab of a sharp ground ball to his left, getting the force out at second to end the frame.
Redmond said Coghlan's value will increase if he can play both the infield and outfield. The Marlins manager is taking the final month of the season to try certain players out at new positions, and that includes Coghlan.
"We need the offense, and right now, at this point, I've said it all year: If you hit, you're going to play, and we'll find a spot for you," Redmond said.
Before Tuesday, Coghlan had only played the infield once in his career, and that came at second base.
• In his last three games, Solano is 5-for-13 (.385) with three RBIs and three runs scored.
• On the Marlins' current road trip, Yelich is 13-for-27 (.481) with five RBIs.
