CLEARWATER, Fla. -- The Phillies' Double A Reading club had 89 wins last season, the second most in all of minor-league baseball.

With Roman Quinn, Jorge Alfaro, Rhys Hoskins, Dylan Cozens and others, the Reading club was loaded with top prospects.

That's why it was so remarkable late last season when a Phillies' official said, "You know, there are nights when Scott Kingery is the best player on the field."

Kingery, a second baseman who turns 23 in April, was the Phillies' second-round pick in the 2015 draft, a former walk-on at the University of Arizona who blossomed into a Pac-12 batting champ (.392) his junior year.

Kingery, 5-10 and 180 pounds of pure ballplayer, was so impressive his first two seasons in the Phillies' minor-league system that he earned an invite to big-league camp this spring.

He is making the most of it.

He had a huge game in the Phillies' 7-5 win over the Baltimore Orioles on Tuesday. He singled, doubled and homered in four at-bats. He also made a couple of nice plays in the field, including a backpedaling, over-the-shoulder grab in shallow right field to end the top of the eighth inning.

The Phillies rallied for four runs to come back from two runs down in the bottom of that inning. Of course, spring star Brock Stassi had the big hit, a three-run homer to put the Phillies ahead.

Stassi, who has two homers and a double in the four games in which he has played, is a serious candidate to win a spot on the Phillies' bench.

Kingery -- who has just 37 games and 156 at-bats of experience above the Single A level -- is not a candidate to break with the big club. But manager Pete Mackanin thinks he might not be that far away.

"I heard a lot about Scott Kingery and how good a player he is and he sure looks like one," Mackanin said after Tuesday's game. "He's made a good impression on me and the coaching staff. Today was a good example of what he can do. He might be on the fast track to the big leagues."

Kingery is a pretty levelheaded kid. As happy as he was with his game Tuesday, he was quite realistic. He needs more seasoning. The blueprint calls for him to open back at Double A and build on the six weeks he spent there last year.

"I feel I need to spend some more time in Double A," Kingery said. "I didn't get much time there last year. I think that's what I'll head back to and just try to figure out that pitching and climb up the ladder from there."

Jesmuel Valentin is expected to open the season as the second baseman at Triple A Lehigh Valley. He is a prospect, as well. He has been slowed in this camp by a sore shoulder.

The Phillies' depth at second base will put some heat on Cesar Hernandez to continue the improvement he showed in the second half of last season. It could also eventually turn Hernandez into a trade chip. According to multiple baseball sources, the Phillies were willing to listen on Hernandez this offseason, though the price was very high.
