"He's done a great job," Trenton's manager Tony Franklin said. "He's very aggressive and that's the only way that you can steal the amount of bases that Ray steals.
"Like most guys at this level, he's trying to find the right technique and the proper mechanics to produce a lot more consistency in his game, but he's doing pretty good so far, and once he's on base you can almost guarantee he is going."
Kruml's .263 batting average is good for third on the team with those who have 150 at-bats or more and his team high 23 stolen bases ranks second most in the Eastern League behind New Hampshire's Anthony Gose.
"If the numbers between me and the pitcher don't match up, obviously I'm not going to push the envelope," Kruml said. "But most of the time the numbers are pretty close so I'm going to try and swipe that bag."
When former Thunder outfielder Austin Krum was called up to Triple-A, Kruml was put into the lead off spot, and has done extremely well since the change, stealing six bases this month already.
"I figure I always would hit either 1 or 2, or 7, 8, 9," he continued. "[Austin] Krum got called up to Triple-A so I got the opportunity to lead off which is always good, but even when he was here I was hitting ninth, which is like a second leadoff spot. I'm happy wherever I get put in the lineup; as long as I'm in the lineup, it's a good thing."
However, Kruml can't steal second base if he doesn't make it to first base. He has made some minor adjustments at the plate, and has been fairly consistent at the plate this season overall.
"I'm trying to be a little more passive in my first couple of at-bats, and then aggressive in the zone," he said regarding his adjustments at the plate. "As long as I'm getting good fastballs in the zone I'm going to try and put good swings on them.
"I'm not trying to be overly aggressive, but also not trying to be overly passive. As long as I get on base I guess no one is really going to complain."
Along with the change in his place in the batting order, Kruml has also been moved to handle the bulk of the action in centerfield during Melky Mesa's absence, due to injury.
"He's handling it pretty good," Franklin said. "He is handling all of the duties that I feel the centerfielder should handle. He's performing all of the duties; he has aggressiveness, and he kind of commands the corner outfielders as to where to play and things of that nature.
"It gives him some extra value," he continued. "People will look at him now as a guy who can play both positions, and he probably could play all three out there and that doesn't hurt you at all."
"I've always played all three positions out there," Kruml said. "In college I played right and left and a little bit of center, and my first year in Staten Island I played center, and I've been playing the corners ever since. I feel comfortable; we always do work in different spots out there so it was a pretty easy adjustment going out there."
"It would definitely be a plus if I could get my on-base percentage up," he added. "[To] get a little bit more walks, a little less strikeouts and put the ball in play and put the ball on the ground, and usually good things will happen."
"I think the best of his offensive ability is yet to come," Franklin said.
