The 39-year-old Jeter received a standing ovation in his first at bat and a rousing reception from the home crowd during pregame introductions.
He also received praise from Showalter, who was Jeter's first big league manager when Jeter debuted with the Yankees in 1995.
"He's somebody who baseball should be proud of," Showalter said. "He understands the responsibility that comes with his tenure here. … I was lucky. It was an honor. … I'd [much] rather him not be playing today, seriously. It's like your grandmother making you go out and getting switches to whip your own butt with. You don't want to do that.
"I take it in," Showalter said. "Are you kidding me? [But] I'm not going to dwell on it. I'll scream at him if he jumps out of the way of a ball that's a strike."
Around the horn
Showalter politely scoffed when asked about Opening Day at Yankee Stadium: "We've got some pretty good history at Camden Yards, too. We're pretty proud of the people on our statues. We've got some statues, too." … Left-hander Johan Santana pitched a two-inning simulated game today in Sarasota, another significant step forward in his progress from a second shoulder surgery in three years. ... Right-hander Dylan Bundy was scheduled to throw a 30-pitch bullpen session Monday, throwing all fastballs. The next step would be incorporating changeups and breaking balls. … Showalter said third baseman Manny Machado had a "step up" day Monday in his rehab from left-knee surgery. … Outfielder Francisco Peguero will start baseball activities and a hitting progression today after getting the cast off his right wrist.
