NEW YORK -- At the end of each Marlins game, Logan Morrison makes checking his Twitter account the first order of business. So his early -- and often -- updates during Tuesday's visit to the MLB Fan Cave came as no surprise.

"Twitter first," Morrison said of his postgame routine. "It's either call Mom, or check Twitter. Usually, it's Twitter."

Morrison's appearance capped a Marlins doubleheader at the MLB Fan Cave, where two fans will watch every Major League game this season. With the Marlins in town for a two-game series against the Mets, first baseman Gaby Sanchez preceded his teammate in the Manhattan hangout.

Sanchez (@GabySanchez15) and Morrison (@LoMoMarlins) maintain active Twitter accounts. Morrison (24,783 followers at last check) has a healthy lead on Sanchez (7,391), but each says there's no rivalry, friendly or otherwise, between the two.

"Absolutely not," Sanchez said. "One, I don't think you can catch him. I don't worry about any of that. I just think it's nice to get on there and talk to the fans who do follow me for whatever reason it is."

Morrison gave a simple "No" when asked if he was looking over his shoulder at Sanchez.

"The more the merrier, though," Morrison added.

Morrison's tweets range from the self-promoting ("USA Today Loves LoMo," with a link) to the self-deprecating. ("For everyone hating on my hair. I know it's bad. In trying to grow it out it's in the in between stage right now.") He says he loves all the feedback.

"Good or bad, it's great," Morrison said. Referring to a recent misplay, he added, "I zooed a ball in left field at Nationals Park the other day. Some of the stuff they were saying was, 'Man, you stink, blah, blah, blah.' I just turned it around and said, 'Did you see that circus in left field in the first inning?' You just turn it around and try to make it funny."

Sanchez says his Twitter account, which is more restrained than Morrison's, is equally indicative of his personality.

"I know he's definitely outgoing, and he says what's on his mind," Sanchez said. "I think it's pretty precise. Mine is pretty precise, too. I'm very low-key, and mine is pretty low-key. I think each of ours represents us pretty well."

For one Fan Cave video shoot, Sanchez traveled from the East Village to Chelsea to be "sold" as a Marlin while sitting on a bed of crushed ice in a fish market.

"I was wanting to ice my hamstrings down, anyway, so it was good to be able to get a jump on it," Sanchez joked.

For his skit, Morrison, dressed in a getaway-day suit, gave some pointers on talking to women.

"Just be yourself," he told Mike O'Hara and Ryan Wagner, the Cave's two inhabitants.

With the Marlins off to a strong start -- entering Tuesday, they sat one game behind the Phillies in the National League East -- Morrison has started a Twitter campaign to get Sanchez elected to the All-Star Game.

"He deserves it," Morrison said of Sanchez, who is hitting .329 with a .411 on-base percentage and seven home runs.

"I think it's funny," Sanchez said. "Whatever he wants to do, he can do. I'm not going to stop him, that's for sure. I feel like it's a nice gesture on his part, too."

A large following can't stop some razzing from Morrison's veteran teammates. Wes Helms, 35, frequently tweaks the 23-year-old Morrison.

"He'll say, 'Did you really put this on Twitter?" Morrison said. "I'm. like, 'No Wes, I didn't. You would know that if you read it.' And it's just back and forth like that."

Morrison's Twitter account started as his agent's idea, but it's now among the more popular ones in baseball, this side of Yankees outfielder Nick Swisher's. What started as a throwaway idea has turned into a good-natured obsession.

"My agent suggested it to me when I was in the Minor Leagues," Morrison said." He's, like, 'I'm going to make the account for you.' I'm, like, 'All right man, whatever.' I got on there a couple of times. Then people started tweeting back and the offseason came along and I got bored, so I got on there a little more. And it just turned into one of those things that snowballed."
