PHOENIX -- That wasn't Adam Rosales doing the 100-meter dash on Sunday. That sprint the Reds third baseman did qualified as a home run trot -- for him.
In the fourth inning of the Reds' 8-7 loss to the Cardinals, Rosales hit Adam Wainwright's first pitch into the left-field seats for his first big league home run.
Despite the ball being gone, Rosales motored around the bases at full speed. During its telecast, Fox Sports Ohio timed him at just over 15 seconds.
"I've been doing it since I was a little kid," Rosales said. "I'm not going to change. I just do it. I think it's fun. It's who I am. I always get razzed about it. That's what makes it fun. Give them a reason. But I'm going to keep doing it."
Did he ever. During the Reds' 13-5 thumping of the Diamondbacks on Tuesday, Rosales sprinted around the bases after going deep to left field in the fourth inning for a 424-foot homer. The homer followed Laynce Nix's leadoff shot for Cincinnati's first back-to-back blasts of the season. Rosales was 3-for-5 in the game with two doubles and three runs scored.
Rosales, who was tagged during Spring Training with the nickname "Pete Rosales" after a certain Cincinnati icon, is always running -- he goes full speed to the field between innings, after making outs and even when he draws a walk. It's not part of an act but just how he rolls.
"I've seen him do that for four years now. It's amazing," right fielder Jay Bruce said of Rosales' home run sprint. The two came up in the farm system together. "It's never been any different. It's always the same, every game."
The 25-year-old Rosales is also a rarity for wearing his red socks up to the knee over his pants.
Rosales was red-hot with a .431 average and four homers when he was recalled from Triple-A Louisville on April 28 after Edwin Encarnacion went on the disabled list. Rosales hit safely in seven of his 11 games entering Monday but snapped a 0-for-15 skid on Friday.
Hits have come over the last three games vs. St. Louis, but none was as satisfying as his first long ball.
"It was pretty thrilling," said Rosales, who entered Monday batting .256 with four RBIs. "I was kind of feeling for the ball the last week or so. That at-bat, I said I would go out there and attack it and not be so passive. I got my pitch to hit."
