The Twins have played roughly half their games this season in difficult, wintry weather, but conditions finally got bad enough Sunday to interrupt the season. When it resumes on Monday, the Twins will have a new phenom to watch, however briefly.

Oswaldo Arcia will be called up to fill Wilkin Ramirez's roster spot while he is on paternity leave, a source close to the team said Sunday, giving Minnesota fans a chance to see one of the highest rated hitting prospects in the team's farm system. Arcia is batting .414 so far this season, with three home runs in nine games for Class AAA Rochester.

It may only be a fleeting glance for Twins fans, because Ramirez, who left the team Saturday after his wife went into labor, is due back with the Twins later this week. Arcia, who has played right field and served as designated hitter for the Red Wings (and was a center fielder three years ago), could play in two or perhaps three games before Ramirez must be taken off the paternity list.

Then again, Bryce Harper was only supposed to remain with the Nationals temporarily, while Ryan Zimmerman's shoulder healed, when he was called up to Washington last April. And the Twins could always choose to send someone else down when Ramirez returns.

Arcia, a Venezuelan power hitter who slugged 36 doubles and 17 home runs at Class A and AA last season, turns 22 next month. He was the youngest member of his team at Elizabethton, Beloit, Fort Myers, New Britain and Rochester, and will become the youngest Twins position player since Joe Mauer made his major-league debut at age 20 in 2004. (Pitcher Francisco Liriano was younger than Arcia by 29 days when he made his debut as a 21-year-old in 2005.)

Of course, he won't get much of a look if the weather doesn't improve. The Twins called off Sunday's game before 9 a.m. on Sunday, with temperatures below freezing and snow falling at Target Field. Forecasts call for precipitation all day; even if temperatures rise, the snow is expected to turn to rain, so the Twins postponed the game until Monday, Aug. 19 at 1:10 p.m., an off day for both the Twins and Mets.

Temperatures are expected to remain in the 40s for a three-game series with the Los Angeles Angels, which begins Monday night.

Fans holding tickets to Sunday's game may use them for the makeup game in August, or trade them in for tickets to a different game. Fans wanting to exchange their tickets must do so at least 48 hours before the game they choose.
