MIAMI -- The next stolen base for Jon Berti will move him into a tie with Miguel Rojas for most on the Marlins.

The total will only be six, but remember, Berti has five in 31 big league games in 2019. Compare that to Rojas, who is on the injured list with a right hamstring strain, who has appeared in 108 games. Brian Anderson also has five in 114 games.

In Berti, the Marlins have a legitimate burner who possesses game-changing speed. In the final two months of the season, Miami is seeing if the 29-year-old has a long-term future in the organization.

In terms of pure speed, Berti ranks among the fastest players in the Majors.

According to Statcast, Berti is 12th overall in sprint speed -- averaging 29.8 feet per second. A competitive run is 27 feet. Of the 61 “competitive runs” tracked by Statcast, 15 are termed “Bolts,” faster than 30 feet per second.

“He’s a full-speed acceleration guy, where he’s at full speed quickly,” Marlins manager Don Mattingly said. “If you’re going to be basestealer, or a guy who has that kind of burst, those guys are at full speed right away. A step. Step and a half. They’re going into gear quickly.”

Berti is playing mostly shortstop now with Rojas on the IL, but he also can move around the infield as well as play right or center field.

“He’s getting a shot here, kind of showing himself,” Mattingly said. “It puts him on the radar. This guy has got a chance to be a piece for us, from the standpoint he can do a lot of things.”

A threat to steal is a reason Berti has been hitting in the leadoff spot when he’s in the starting lineup. On Saturday, he was given a breather, though.

“We want to be athletic,” Mattingly said. “We want to put pressure on teams. We want to be able to have guys who put the ball in play. There’s a lot of things that we want from this roster, moving forward. He fits that criteria, a guy that can put pressure on the other team. He can steal a base. He can go first-to-third. He’s going to score from first on a ball in the gap. All of those things put pressure on the pitcher, from the standpoint of having to hold the runner.”

The Marlins would like to run more, they just haven’t had the personnel to regularly be a threat on the bases. Berti, Rojas and Anderson are the only three on the club with as many as five steals.

“He’s part of that equation that can put pressure on the other team, just with speed,” Mattingly said. “I think that’s important for us, knowing the kind of roster we’re trying to build. That’s the kind of guy you’re looking for.”
