But that's not the case with Rockies right-hander Jhoulys Chacin, who has flourished since spending nearly four months on the shelf with an injured pectoral muscle.
Returning to the Colorado rotation on Aug. 21, Chacin has allowed just three earned runs over 18 innings, resulting into two victories.
The 24-year-old will look to continue his hot streak when he takes the mound on Thursday for the final game of the Rockies' four-game series against the Braves in Atlanta.
In his most recent start, Chacin surrendered one run on five hits over seven innings to beat the Padres, 9-1.
Although Ramon Hernandez caught Wednesday's game, manager Jim Tracy will go back to Wilin Rosario behind the plate for Chacin.
"I just felt like the way that Rosario and Chacin did their business the other day against San Diego, we'd give them an opportunity to do it again," Tracy said.
Opposing Chacin will be the veteran right-hander Tim Hudson. The 37-year-old is coming off a subpar outing his last time out, as he gave up five runs over five innings to the Phillies in a Braves loss.
"Honestly, I wasn't very good today," Hudson said after that game. "They caught me on a bad day, and it was a one-sided ballgame."
Rockies: McBride and Scahill join club
Utility player Matt McBride and right-hander Rob Scahill joined the Rockies on Wednesday after Tracy announced earlier that the pair would be called up from Triple-A Colorado Springs this week.
McBride was activated before Wednesday's game; Scahill will be officially activated on Thursday.
Tracy said that because Scahill threw 80 pitches in five innings for Colorado Springs in Monday's season finale, he would have been unavailable to pitch on Wednesday.
Braves: Simmons nearing return
The Braves have not set an exact return date for Andrelton Simmons, but if the shortstop progresses through his Minor League rehab games without any problems, he could be in the lineup for one of the first two games of this weekend's series against the Mets.
Simmons was scheduled to play with Class A Rome on Wednesday night and with Class A Advanced Lynchburg on Thursday night. Both teams are in the middle of a best-of-three playoff series. If the Lynchburg series is extended to a third game, there is a chance Simmons could also play on Friday night.
The 22-year-old has been sidelined since breaking his right pinky finger while sliding into second base in Philadelphia on July 8.
"He looked great on Sunday," Braves manager Fredi Gonzalez said. "He took some [grounders] off the bat. He looked like he was in midseason form."
In addition to providing a dependable glove, Simmons hit .296 with a .788 OPS in 33 games with Atlanta.
The Braves have plated two runs or fewer in nine of their last 12 losses.
Colorado's Jordan Pacheco is riding a 14-game hitting streak.
