"I love the at-bats from the bottom," Mattingly said. "It was nice to see a balanced attack from the standpoint of everybody being involved and everyone giving us something."
Over the last week, Rojas is 6-for-14 (.429) -- including a 4-for-5 night on Wednesday -- and Hechavarria is 7-for-19 (.368). Catcher J.T. Realmuto, the team's regular No. 7 hitter, can also be added to that group, although his 2-for-5 with four RBIs performance on Wednesday came out of the leadoff position with Dee Gordon getting the night off.
"I haven't seen Dontrelle around, so I don't know if he truly knows what we have," Mattingly said. "We are what we are. This is our staff."
The Marlins' starting rotation has a 4.89 ERA this season, third highest in the Majors. Mattingly said that those numbers aren't a result of not having enough fight.
"This is our rotation. I don't take any offense to [Willis' tweet], but I also can't give him a lot of credibility because he's not really here," Mattingly said. "This is our team. We'd love to have a [Clayton] Kershaw or a [Madison] Bumgarner and every best pitcher in baseball, but this is our team. We put the best rotation we could together.
"Our guys are competing and fighting. Do we want better? Absolutely, but I don't think it's a lack of wanting to [succeed]."
