"I saw the video, he came out of it healthy and the homer was a really good swing," Roberts said Tuesday before a 7-4 win over the D-backs. "It was a line drive to right-center and the mechanics looked better than when he was here. The challenge is for him to sustain that, but it was positive."
Puig was scheduled to play again Tuesday night, rest Wednesday, then play three more games with Class A Rancho Cucamonga and head to Los Angeles. Roberts said it won't be necessary for Puig to face a higher level of competition.
"For certain people, maybe, but in a short stint, it's more for Yasiel to get the hamstring right," Roberts said. "Mechanically, where he was at before, he would have a tough time regardless of what level. And conversely, if his mechanics are right, he can handle any pitching."
Puig was hitting .237 with five homers and 20 RBIs in 53 games when he went on the DL. Since Puig has been sidelined, rookie Trayce Thompson has been the primary right fielder. Thompson was hitting .265 with 10 homers and 23 RBIs in 54 games entering Tuesday.
