He spent a few minutes trying to get different types of spikes. Horwitz walked around talking to teammates here and there in a low-key manner. In other words, he was acting just like a rookie who's been in the Major Leagues for a little over a week.
But Horwitz has certainly done a lot in that time. Since the Giants purchased his contract from Triple-A Fresno on May 30, Horwitz is hitting .417 with one homer and three RBIs and already caught the attention of his manager.
"Brian's been a shot in the arm for us," said Giants manager Bruce Bochy. "We needed a right-handed bat, and he has supplied not just base hits but made a big home run for us, played a good left field [and] done a good job."
Horwitz got his first two Major League hits on Sunday against the Padres. His initial hit came on a second-inning single versus Randy Wolf as part of a 2-for-4 day in his first Major League start.
The hits kept coming when Horwitz was in the lineup on Monday against the Mets. He went 2-for-3 in that game, including a key two-run homer as the Giants scored six runs in the first inning.
"I just have to take advantage of the opportunities, whatever they may be, in front of me and show them that I belong up here," Horwitz said. "I believe I belong up here, and I hope they do too."
The Giants called Horwitz up to replace Daniel Ortmeier, who went on to the disabled list. Horwitz had been hitting .294 at Fresno with five homers and 18 RBIs.
Right now, he's just trying to get adjusted to life in a Major League clubhouse. Horwitz is working his way around, meeting people and finding his way. He's the new kid on the block.
"I'm just trying to become more comfortable with the team and the personnel here," he said. "Everybody's been great."
The Giants signed Horwitz as a non-drafted free agent after he played at Cal in college. Horwitz's hitting skills have been evident since the start, as he's led two leagues in hitting (Northwest in 2004 and South Atlantic in 2005).
And those hitting skills already have shown up in the Major Leagues. Horwitz just smiled when asked about the best moments of his first week.
"The first hit and the first home run were pretty sweet," Horwitz said. "They were both pretty cool. It's all been good. All of it's been [fun]."
