Pitcher who faced top Giants prospects Ramos, Luciano, Bart shares intriguing intel

For young ballplayers, one of the beauties of a normal minor-league season is facing different opponents and learning about different talents, tendencies and track records.

Nowadays, that’s impossible. At the Giants’ alternate site in Sacramento, where players from the 60-man pool who aren’t on the active roster are working out, the competition strictly is in house.

“It’s tough because you’re pretty much seeing the same uniforms every day,” said pitcher Dereck Rodriguez, who was recalled to the majors Wednesday. “You’re facing the same guys.”

On the other hand, it allows Giants farmhands to know each other more than ever — pitchers knowing hitters and hitters knowing pitchers — so Rodriguez has an excellent handle on the organization’s top hitting prospects.

His glowing scouting reports will make Giants fans want to fast forward to the future and envision a lineup of front-line homegrown players.

Rodriguez has joined a long line of Giants big-leaguers who, when quizzed, said catching prospect Joey Bart is major-league caliber now. But the same could be said of an outfield prospect who’s three years younger, 20-year-old Heliot Ramos.

“Heliot Ramos, that dude has some pop like no other,” Rodriguez said. “I don’t think I got Ramos out once.”

Defensively, Rodriguez said, Ramos is a “great runner, reads the ball really well off the bat, has a really good arm.”

And at the plate, “He sees spin really well. He’s a good, disciplined hitter up there. In my opinion, I think he could be up here at any moment.”

Shortstop Marco Luciano, 18, is the heir apparent to Brandon Crawford, and Rodriguez marvels over his plate discipline and calls him a tough at-bat.

“He’s a big boy. Man, he could hit,” Rodriguez said. “Usually for younger guys, 2-0, 3-0 counts, they’re usually fastball counts. But to him, you have to treat him pretty much like a veteran because he makes good adjustments, so it’s pretty cool.”

Bart is furthest along among the top prospects, and many a Giants fan desires his presence in a big-league uniform as we speak. Management stresses more development and the preference for him to be fully prepared both at the plate and behind the plate once he gets the call.

“Bart’s unbelievable,” Rodriguez said. “He’s a big-league player, if I could say it. He’s awesome to throw to. He’s awesome calling games. He looks like a veteran at the plate.”

Rodriguez continued his praises, “Everybody loves Bart. I feel a lot of pitchers up here who threw to Joey in camp are really impressed and really excited to try to get him up here at some point, either by the end of the year or next year. It’s going to be a lot of fun seeing him up here and throwing to him.”

The Sacramento camp is much like Spring Training 2.0 at Oracle Park, where players went through their training and then played intrasquad games lasting four or five innings.

Rodriguez expressed the benefits to facing the same players over and over, including the art of making adjustments, which can maintain the competitive juices.

“Say I face Joey two times yesterday and I’m facing him again two days from now,” Rodriguez said. “He had certain at-bats against me and did certain things. I want to switch it up a little bit and see if he made that adjustment.

“That’s what minicamp is teaching a lot of the younger guys. Me, too. The first game I went out and faced one set of guys and threw fine. Next game I went out and faced the same set of guys, and they had a different result on me.

“So making adjustments even in minicamp are things to learn.”
