With the regular season underway, here is a look at some of the Rookie of the Year candidates for the 2023 season. 

American League 

Gunnar Henderson (Baltimore Orioles) 

Henderson came up last year and is a big part of what the Orioles are looking for as they seek to build on last season's reasonable success. 

The 21-year-old can play shortstop and third base. There is power in his bat and he has speed around the bases, showing this off when he made the jump from Double-A to the big leagues. 

He's the number one candidate for Major League Baseball, but has made a sedate start to the new season. He is expected to improve, however, and is priced at 13/4 to win the American League Rookie of the Year award.

Anthony Volpe (New York Yankees)

Volpe, 4/1 to win the award, made the opening day line-up and kissed the badge when his name was called by the bleacher creatures at Yankee Stadium. 

While he managed his first hit against the Giants and drew a standing ovation from those in attendance, he has a 3-for-17 record so far with a .176 batting average, but it remains early days. 

He had such a good spring training that manager Aaron Boone couldn't wait to call him up and make the opening day. Patience will be the key for Volpe's prospects moving forward.

Masataka Yoshida (Boston Red Sox) 

Yoshida hit his first home run of the season despite it being in a losing situation for the Red Sox. With Boston not expected to get to the playoffs this season, they still have some future in their line-up with Yoshida and Triston Casas. 

Team manager Alex Cora spoke of Yoshida's home run, telling Red Sox's website: "We know he (Yoshida) can do that, he's going to go the other way. He's going to use the wall, he's a good hitter."

The only sad note was that he hasn't managed to obtain the ball that he hit his home run with. Apparently he is in negotiations with the person who managed to grab it. Yoshida is 9/2 to win Rookie of the Year award.

Other candidates include: Triston Casas (Boston Red Sox); Grayson Rodriguez (Baltimore Orioles); Hunter Brown (Houston Astros).

National League 

Corbin Carroll (Arizona Diamondbacks) 

The Diamondbacks traded Daulton Varsho during the offseason to create even more room for Carroll in the outfield. Carroll played 32 games last season and looked very much the part just after he turned 22 years of age. 

He's one of the best all-round tool packages you could ask for in a young player and is 3/1 for the National League rookie award. 

He's got power and solid arm strength and is highly thought of in the Diamondbacks management team. Carroll has a home run this season and an average of .222. 

Jordan Walker (St.Louis Cardinals) 

Walker has started the season in a really positive manner with a batting average of .333, eight hits in 24 at-bats with one home run and five RBI's. Walker took his form from Double-A last season and the fact he managed to make this loaded Cardinals team is quite something. 

Walker spoke to the official St.Louis Cardinals website about his first home run: "It was a pretty good feeling, but we were kind of down, so I was trying to lock in toward the game. 

"So, maybe later I can enjoy the moment, but during the game, I was trying to focus and trying to come back against that team." 

He sounds a level-headed person and, as the Cardinals look to make the playoffs again for the fifth consecutive season, he is 4/1 for Rookie of the Year honours. 

Kodai Senga (New York Mets) 

The Japanese star who has an Olympic gold medal and performed superbly in the 2017 World Baseball Classic is 13/2 to win the award. He asked not to be considered for the squad in this year's tournament as he had just moved to New York and wanted to concentrate on his new team. 

He has a mid-90's fastball, and a wicked forkball called the ‘ghost-fork', so that may earn him some votes this season. 

He's signed a $75 million deal, so the Mets are expectant of him and he had a pretty good start with a 1.69 ERA in his first game won against the Miami Marlins. 

Other candidates include: Miguel Vargas (Los Angeles Dodgers); Ezequiel Tovar (Colorado Rockies); Cade Cavalli (Washington Nationals)
