Bombers bits

• Arenado, Yankees catcher Austin Romine and Mike Gonzalez -- their coach at El Toro High School in Lake Forest, Calif. -- had dinner on Monday night. Romine, who was two years ahead of Arenado in high school, said of the third baseman, "I'm excited to see him play" and that it should be memorable for Gonzalez to see two of his former players in the Major Leagues.

• Yankees right-handed reliever David Robertson said after throwing that his left hamstring felt fine and that he hoped to pitch on Tuesday night. He had tightness in the back of the hamstring, where it meets the knee.

• Yankees infielder Jayson Nix returned to Coors Field for the first time as a visiting player on Tuesday and singled in his first at-bat. He began his career in the Rockies organization -- Colorado took him 44th overall in the 2001 Draft -- and played 22 games for the Rox at the outset of '08 before being optioned to Triple-A Colorado Springs. After that season, Nix moved on to the White Sox, Indians and Blue Jays but didn't play at Coors Field until returning as a member of the Yankees.

• Girardi and first-year Rockies manager Walt Weiss were Colorado teammates in 1994 and '95. Girardi said, "I always thought Walt would make a great manager. He definitely knew the game. It was just a question of what he wanted to do with his life after baseball. I think it's a great opportunity for him, and I think he's doing a great job."

• With their series at Coors Field, the Yankees began their first Interleague series this season at a National League ballpark.

Asked whether he was worried about his pitchers hitting, Girardi said, "A little bit, just because it's not something they do every day."

As far as any instructions for his hurlers on the basepaths, Girardi said, "Be smart. Just please be smart. Go station to station."
