Maybin is batting .210 with a .308 slugging percentage entering Monday's game at St. Louis. Two months ago the Padres guaranteed him $25 million as part of a five-year contract.
The scout said Maybin's swing glitch prevents him from getting the barrel to a variety of pitches. He said Maybin's spot in the lineup is irrelevant to his slow start.
"It's my understanding Maybin has refused to make any adjustments with his lead arm," the scout said. "He's got his elbow stuck almost in the strike zone and he's blocking off his back half. You can't get the back half of your body into it if the front half is stopping it." The problem isn't unusual, he said.
Maybin turned 25 last month. He is coming off his first full season in the majors. This season he has played in all but two of the team's games. In the 11th inning of Sunday's game with the go-ahead runner on third base and one out, Maybin received the green light on a 3-0 pitch, an 89-miles-per-hour fastball, down the middle and belt high. He fouled it off the end of the bat and went on to strike out.
The scout applauded the Padres for replacing their starting middle infielders -- the veterans Jason Bartlett and Orlando Hudson -- with younger players Everth Cabrera and Alexi Amarista, even as he questioned whether they are a long-term solution.
"Those two kids can get to balls that the other two couldn't think about," he said. "Now, the Padres can get to the ball and have a chance to make a play. Whether they make it or not, who knows.
"The Padres still have no margin for error," the scout said, "and because of it, in the fifth inning, Bud Black has to play the game like it's in the bottom of the ninth every inning."
