GOODYEAR, Ariz. -- Despite it being one set of drills in the early days of Spring Training, some people can still stand out from time to time. On Sunday, during ground-ball and double-play drills, it was shortstop prospect Didi Gregorius.

Gregorius, 22, went to his right and deep into the hole on one play to stop a grounder and made a great throw across his body to first base. On a couple of other chances, he adjusted to bad hops and slickly picked the ball.

"I'm trying to work on defense a lot because I'm trying to get better and better and make progress," Gregorius said. "As I've gotten older, I've learned to slow the game down instead of rushing myself."

Gregorius committed 32 errors at Class A ball in 2010 and improved to 21 errors while splitting last season between high Class A and Double-A. According to, he is the organization's No. 7 ranked prospect. Baseball America rated him as the organization's best defensive infielder and best infield throwing arm.

Born in the Netherlands and raised in Curacao, Gregorius speaks fluently in English, Dutch and Spanish. He was added to the 40-man roster after last season and is enjoying his first big league camp.

"I was really excited," he said. "I finally got a chance to see guys in the big leagues and play with them. It is fun."

In 84 games at Class A Bakersfield and Double-A Carolina in 2011, Gregorious batted .289 with seven home runs, 44 RBIs and 11 steals.

Reds working on extension with Marshall

GOODYEAR, Ariz. -- Left-handed reliever Sean Marshall has yet to throw a pitch for the Reds this season, but he's close to getting a long-term contract extension.

"We are talking to him," Reds general manager Walt Jocketty said on Sunday. "It could be done soon. When we traded for him, it was also looking to sign him for the long term."

Marshall, 29, is set to earn $3.1 million in the final year of the current contract he signed with the Cubs and could become a free agent after the season. Chicago traded him to the Reds in December for pitcher Travis Wood, outfielder Dave Sappelt and Minor League infielder Ronald Torreyes.

Last season, Marshall went 6-6 with a 2.26 ERA in 78 games, with 17 walks and 79 strikeouts over 75 2/3 innings. He has a 2.45 ERA in 158 appearances over the past two seasons.

The Reds plan to use Marshall this season as a left-handed setup man in the late innings. He also has the ability to be a closer in games when Ryan Madson is not available.

Worth noting

Johnny Cueto, Homer Bailey, Mat Latos, Sam LeCure and Aroldis Chapman were among the Reds pitchers who threw in live batting practice on Sunday. The hitters had a lot of trouble against Cueto. Todd Frazier cleared the left-field fence against Chapman.
