On a night Alfredo Simon will try to recapture his All-Star form in front of a group of Reds franchise elite -- the members of the team's Hall of Fame who are on hand for the induction of Ken Griffey Jr., Ron Oester and Dave Parker, along with 19th-century first baseman Jake Beckley -- the Marlins will have a throwback of their own, sending veteran Brad Penny to the mound at Great American Ball Park on Saturday.
When Simon last took the mound for the Reds on Monday, Indians hitters torched him for five runs in five innings. That dropped the All-Star right-hander, who had a 2.70 ERA and a 12-3 record in the first half, to 0-4 and a 5.06 ERA in the second half.
Since then, the rest of Cincinnati's rotation has put up enviable numbers. Over the last four games, three of which the Reds won, starters have yielded seven runs in 30 2/3 innings for a 2.05 ERA.
He'll be trying to reverse his recent trend against Penny, whose contracted was selected following the Marlins' win in Friday's series opener. Penny will pitch for the organization for the first time in 10 years. The 36-year-old right-hander was dealt from the Marlins to the Dodgers in July 2004 as part of the Paul Lo Duca trade.
Penny broke in with the Marlins in 2000, and he was 14-10 (4.13 ERA) on the 2003 World Series championship team. During that remarkable season, he won two games against the Yankees in the World Series.
A former teammate of Miami manager Mike Redmond, Penny also is making his first appearance in the big leagues since 2012, when he made 22 relief appearances with the Giants. His last start came with the Tigers in 2011.
"I'm excited for him," Redmond said. "For me, it will be fun. I caught a lot of his starts. To see him out on that mound, and me managing him -- it's kind of fitting. ... We need him to come in and have some big starts. He knows that."
Penny has been staging a comeback in Miami's system, going 2-2 with a 2.28 ERA in five starts at Triple-A New Orleans.
What Penny's doing hasn't been accomplished much in the last 25 years. According to Stats LLC, the last five pitchers to have 10 seasons between starts for the same organization are Miguel Batista with the Expos/Nationals (1999/2010); Mike Hampton with the Astros (1999/2009), Al Leiter with the Yankees (1989/2005), Greg Maddux with the Cubs (1992/2004) and David Cone with the Mets (1992/03).
Marlins: Hectic times lead to call for arm
Thursday night's loss in Pittsburgh had a ripple effect on the Marlins for their series in Cincinnati. The bullpen was thinned after Brian Flynn worked four-plus innings. The 'pen also suffered a loss when lefty Dan Jennings sustained a concussion after being struck on the side of the head by a line drive.
So, prior to Friday's game, some relief help was added. Lefty Edgar Olmos and right-hander Anthony DeSclafani were promoted to add depth, although Olmos was optioned after Friday's win to make room on the roster for Penny.
"With what we went through, we had to get a couple of fresh arms," Redmond said. "We had to get these guys in here to get us through these next couple of days."
DeSclafani, who has been a starter for most of the year in Miami and New Orleans, is a multi-innings option out of the bullpen.
Reds: Pena leaves game with tight hamstring
Entering Friday, the Reds had won seven of their last 10 games after going 1-9 to kick off the second half. A key contributor to the Reds' resurgence has been catcher-turned-first-baseman Brayan Pena, who tied a career-high hitting streak of 12 games on Friday with a single in the second inning.
After he reached base, Pena was visited by trainer Paul Lessard and manager Bryan Price. They left him in the game until the end of the inning, but replaced him at first with Todd Frazier in the third.
Pena was diagnosed with a tight left hamstring and was removed for precautionary reasons, the club announced.
Pena's start at first base on Friday was his 28th as the primary replacement for the injured Joey Votto. Before this season, Pena made just four appearances (no starts) there in his career.
• Adeiny Hechavarria was hitless on Friday, but the Marlins shortstop has been heating up at the plate, posting a .317 average (19-for-61) since July 22. He has recorded at least one hit in 12 of 17 games, with seven multi-hit efforts. Entering Friday, the seven multi-hit games were tied with Josh Harrison and Denard Span for third most in the NL in that span, behind Daniel Murphy and Ben Revere (nine).
• Since the All-Star break, Reds pitchers are 8-13 with a 2.91 ERA in 188 2/3 innings and rank second in the NL.
