If there's one knock on the righty, according to pitching coach Randy St. Claire, it's that Sanchez sometimes tries to do too much.
"To me, that's his biggest [issue]," St. Claire said. "That's not a physical thing, that's a mental thing to overcome. The mental part of the game is the toughest. It's an old cliche, you hear it all the time. 'Eighty, 90, 95 percent of the game is mental.' But it is. It's a fact.
"At this level, everybody has the ability. But the ones [who have success] are the ones who keep that mental approach in check. Those are the ones who have the high level of success."
Sanchez will look to keep that approach in check when he takes the mound Tuesday afternoon against the Brewers as the Marlins look to bounce back after having their four-game win streak snapped Monday.
Opposing Sanchez will be righty Marco Estrada, who is coming off a career-high and Milwaukee season-high 12 strikeouts in his last outing.
Despite the Brewers sitting firmly in fourth in the National League Central, manager Ron Roenicke believes his team isn't out of it yet. He hopes Estrada can help the Brewers extend their three-game win streak and climb back into the division race.
"We haven't had that consistent week, two weeks where we're really good in all aspects of the game," Roenicke said. "I know we're getting deeper into the season. We need to have it happen. But I still think it's there, that it can happen."
Marlins: Bonifacio to start rehab assignment
Center fielder Emilio Bonifacio, who has been on the disabled list since May 20 and underwent surgery May 25 to repair a ligament in his left thumb, is expected to start a rehab assignment with Class A Jupiter on Wednesday.
Bonifacio is scheduled to play continuously with the Hammerheads through the All-Star break, and the Marlins hope to reactivate him on July 13, when they host the Nationals in their first game after the break.
Brewers: Roenicke wants to keep Greinke
Brewers management met with free-agent-to-be Zack Greinke to address trade rumors surrounding the righty, who started Monday's series opener. Before the game, Roenicke made it known that the team hopes to keep its star pitcher in Milwaukee.
"We are hopeful that we will bring him back," Roenicke said, "whether it's right now, whether it's after the season. There's a lot of possibilities with him coming back."
Marlins first baseman Greg Dobbs celebrated his 34th birthday Monday and went 1-for-3 to extend his hit streak to six games. Brewers outfielder Nyjer Morgan celebrated his 32nd birthday and went 0-for-5.
