JUPITER, Fla. -- Trever Miller didn't pitch Saturday, but he might have worked harder than any of his teammates who did.

Miller ran the Spring Training Classic 10K race early Saturday morning, clocking the six-plus miles in a personal-best time of 44 minutes, 31 seconds. That ranked 45th overall out of more than 500 finishers, and eighth in his age group.

"I was trying to get under 48 [minutes]," Miller said. "I haven't had a chance to run a whole lot of those without pushing my daughter, so I've only got a couple to go on. I believe 45 was my best one. So today was a good day. I was looking to get under 48. The weather was perfect, nice race, beautiful course. They did a good job, ran very smoothly with their inaugural one. I got after it."

When he neared the finish line, he was greeted first by Cardinals manager Tony La Russa and Marlins manager Fredi Gonzalez. The two skippers were waiting near the entrance to Roger Dean Stadium, which marked the final segment of the race. When he got to the end, plenty more friends and teammates were waiting with congratulations, including fellow relievers Jason Motte and Josh Kinney.

Miller has run marathons, but only in the offseason. Running a race during Spring Training is a bit of a different challenge. He would not have run it if he had been scheduled to pitch on Saturday, but the schedule worked out.

"He's amazing," La Russa said. "He really is."
