Northwest Arkansas’ Bobby Witt Jr. watches his home run sail out at Wolff Stadium on Wednesday.
Some players who are likely to be a big part of the Kansas City Royals’ future are playing in San Antonio this week.

Bobby Witt Jr., the No. 2 pick in the draft just two years ago, had a big night in the Northwest Arkansas Naturals’ 3-2 victory over the San Antonio Missions on Wednesday at Wolff Stadium. Witt had a double, triple and home run for the Naturals – the Double-A farm club of the Royals.

The Naturals are playing a six-game series against the San Antonio Missions that runs through Sunday at Wolff Stadium.

Alec Marsh was the starting pitcher on Tuesday for the Naturals. Northwest Arkansas catcher MJ Melendez had a home run in Tuesday’s game. First baseman Nick Pratto is also a home run threat.

Marsh, Pratto, Melendez and Witt have all been high picks by the Royals in recent drafts and are all highly regarded prospects.

Witt has 11 homers on the season and is batting .257 with 19 RBIs in 34 games. He was drafted out of Colleyville Heritage High School in Colleyville, Texas (DFW area) in 2019. He played in rookie league in 2019 and this is his first season above that level.

Witt’s name should sound familiar. His father, Bobby Witt, pitched 16 seasons in the majors including 11 with the Texas Rangers. The senior Witt had a 142-157 major league record with a 4.83 ERA.

Melendez is batting .265 with 11 home runs and 23 RBIs in 31 games this season. Melendez was a second-round pick, No. 52 overall, in the 2017 draft as a high school player in Miami.

Pratto is batting .306 with 11 home runs and 26 RBIs in 34 games in his first season above Class A. He was a first-round pick in 2017, No. 14 overall, as a high school player from Huntington Beach, Calif.

Marsh fits the Royals’ pattern of using high draft picks on pitchers from major college baseball programs. He was taken No. 70 overall in 2019 out of Arizona State. This is his first season above Class A and he has a 1-3 record with a 4.97 record in six starts. He pitched 1 2/3 innings against the Missions on Tuesday and allowed one run, one hit and two walks with three strikeouts.

You get the feeling that Yordan Alvarez is going to be playing in the majors very soon.

And that the 21-year-old from Cuba is going to stay in the majors for a long time.

The 6-foot-5, 225-pound outfielder is currently with the Round Rock Express, the Triple-A farm club of the Houston Astros. The word around the league is that Alvarez will continue to improve his skills in the outfield. He has also seen time at first base for the Express.

His left-handed batting skills have already made him one of the biggest offensive threats in Triple-A and the Pacific Coast league.

Here is how Alvarez ranks in Triple-A as of May 23, 2019 (41 games played):
1st in batting average – .396
1st in total bases – 133
2nd in home runs – 19
2nd in RBIs – 57
2nd in hits – 61
3rd in doubles – 15
3rd in runs scored – 39

The Round Rock Express are currently at home for a four-game series against the San Antonio Missions. The series continues tonight and concludes Friday, weather permitting.

    New Orleans Baby Cakes pitcher Zac Gallen looked dominant on Wednesday night at Wolff Stadium.

    Actually, the 6-foot-3 right-hander looked about the same as he has all season.

    Gallen pitched seven innings and gave up one run on two hits with seven strikeouts and three walks. Gallen (5-0) got the win in the Baby Cakes’ 5-2 victory over the San Antonio Missions.

    Gallen has allowed either one or zero runs in five of his seven starts this season. He gave up two runs in his other two starts.

    The third-round draft pick by the St. Louis Cardinals in 2016 has been so strong this season that by giving up one run to the Missions, his ERA went up from 1.19 to 1.24. Gallen is the No. 18 prospect in the Marlins organization, according to MLB.com.
