SAN FRANCISCO -- The Giants swapped out rookie center fielders as part of a flurry of transactions on Monday, with Wade Meckler coming up from Triple-A Sacramento to replace Luis Matos on the 26-man roster. 

Like Meckler, Matos arrived in the midst of a torrid stretch at the plate, but the 21-year-old Venezuelan struggled to sustain that production with the Giants, slashing .241/.306/.316 with one home run over his first 50 games in the Majors. 

Matos possesses elite bat-to-ball skills, but he ranked in the 25th percentile in exit velocity and often wasn’t getting rewarded for making solid contact. Manager Gabe Kapler said the Giants have spoken to Matos about adding more strength to his 5-foot-11, 160-pound frame to ensure that more of those balls start to fall for hits in the future. 

“We’ve seen that that’s been a little bit frustrating for Luis,” Kapler said. “Some of that will just work itself out with time as he gets more physically mature, but he does have some ability to put some extra work on the strength training side. He doesn't have to do anything different with his swing. It's not a, 'Make this swing change or that approach change.' That all looks pretty good right now. It's more, we want him to get rewarded for the good, solid contact. He can get a little stronger, so we discussed that."

Another point of emphasis for Matos will be working on his jumps in the outfield, where he recorded -4 Outs Above Average in center. Matos seemed to especially struggle with balls in front of him and made some mental mistakes, including throwing to the wrong base on a couple of occasions.

"I think he put a little bit of pressure on himself," Kapler said. "He kind of got off to a rocky start with respect to the jumps and then he put a little bit more pressure on himself to get a better jump and maybe second-guessed himself a little bit. You could see that happening, where it just took him a second to recognize where the ball was going to be before he went after it. But what I really liked about the end with Luis in the outfield was he started putting in his brain that he could catch any ball, and that helped him finish a couple of plays that he might not otherwise have finished.”

The Giants still view Matos as a key piece of their future, and they want him to set a high bar for himself as he continues to develop both offensively and defensively. 

“Two goals that we talked about -- two long-term, big-picture, high-ceiling kind of goals -- is to win a Gold Glove and to win a batting title,” Kapler said. “I’m not saying you go out and do those things just because you set the goal, but that’s sort of his skill set.”
