NEW YORK -- Bubba Watson left his clubs at home, but he was still pondering trick shots when he walked out of the dugout at Citi Field on Monday.

"It'd be pretty fun here to try and hit over those big signs," Watson said. "I would love to just try and hit one off the lights like the movie 'The Natural.' That was one of the best baseball movies of all time, and watching the lights explode like that, that'd be fun to try and do with a golf ball, because I couldn't do it with a baseball.

Watson was cool under pressure this past April, when he won the Masters in a dramatic playoff for his first career victory at a major tournament. But the 33-year-old faced a whole new kind of pressure on Monday, when he threw out the ceremonial first pitch before the Mets' series opener against the Orioles. Watson had previously thrown out a first pitch at the Reds' Double-A affiliate in Pensacola, Fla., but Monday was the only time he has toed the rubber in a Major League ballpark.

"It got there all the way, but it's funny, when you don't warm up and you don't stretch and you don't do all that stuff, your old bones start feeling it after a while," Watson said. "So for me, when I reared it back I was like, 'I better lob it over the plate.'"

Watson was eliminated from the U.S. Open this past weekend after he shot a 78 on Thursday and a 71 on Friday, but he did get to experience another major first moment in his life because of it. Although he was disappointed with the result of his golf game, he was overjoyed he had the chance to spend his first Father's Day as a dad with his recently adopted son.

"It was unbelievable," Watson said. "It was sad that I wasn't playing golf, but to be able to spend the time with my son and be there all day with him and my wife, it was a blessing and it was very fun."

Bay visits doctor, will continue to rest

NEW YORK -- The Mets remain stuck in a holding pattern with concussed outfielder Jason Bay, who saw a doctor on Monday and plans to return for a follow-up on Tuesday. Between visits, Bay is doing little more than resting at his Westchester home while he waits for the symptoms of his concussion to subside.

"I don't think we know how serious it is yet," general manager Sandy Alderson said. "We may not know for at least a few days."

Alderson indicated that Bay's "more obvious symptoms" still have not dissipated since the outfielder tumbled into Citi Field's left-field wall on Friday evening, hitting his head against the padding. Bay, who was batting .187 with four home runs in 22 games prior to his injury, missed the final two-plus months of the 2010 season with a concussion. He also sat out six weeks earlier this year with a fractured left rib.

"In this case, I think you've got to let things settle down a little bit before you make an evaluation about when somebody's going to come back," Alderson said. "The thing we don't want to do right now is put any pressure on him to feel as if he's got to come back right away. That's not the case. He may be out quite a while."

Tejada resumes rehab with Class A St. Lucie

NEW YORK -- Live games are on tap for Ruben Tejada, who restarted his rehabilitation assignment on Monday with Class A St. Lucie. But that does not make the Mets' shortstop situation any less murky. Until Tejada can prove that his strained right quad is completely healthy, the Mets will not push him to return.

"I want to make sure, first of all, that his legs are in good shape," manager Terry Collins said. "We're making some progress. But I want to make sure this guy's legs are in shape before he gets back here."

Tejada nearly made it back to the Mets earlier in June, before suffering a second setback in his rehab and returning to Florida for further treatment. Wary of yet another step backward for Tejada, who has been sidelined since May 7, the Mets will proceed even more cautiously this time with their starting shortstop.

Though backup Ronny Cedeno is edging closer to his own return from a strained left calf, continuing his rehab assignment on Monday with Triple-A Buffalo, Cedeno is also still a few days away. Omar Quintanilla will remain the Mets' regular shortstop until Cedeno is ready to rejoin the club

Worth noting

• Reliever Ramon Ramirez began a Minor League rehab assignment on Monday with Class A St. Lucie. Ramirez has been sidelined since May 31 with a strained right hamstring.

• The Mets played a role in Major League Baseball's record-setting Father's Day weekend, drawing 102,838 fans to three games at Citi Field. That included their second- and fourth-best attended games of the season, marking the second time this season they have drawn over 100,000 fans to a three-game series. In all last weekend, more than 1.6 million fans attended 45 MLB games.
