The Mariners' No. 3 prospect was 3-for-3 with two runs scored as Peoria beat Scottsdale, 4-3, on Wednesday in the Arizona Fall League.
Franklin sparked the Javelinas' offense early, singling with one out in the first inning and scoring on Brewers prospect Kentrail Davis' triple. Two innings later, the 20-year-old shortstop led off with a triple and gave the Javelinas a 3-2 lead when Davis doubled him home.
"Being selective at the plate, getting my pitches and having fun," Franklin said. "Just going out and playing like it's the last game of the season."
Franklin had a rocky regular season in 2011, batting .281 with seven homers and 26 RBIs in 88 games over three levels in the Minor Leagues. The Florida native missed a month of the regular season after being struck in the head with a bat.
"It's been a grind and just overall pushing through the injury, you can't control anything about it," he said. "It took its toll and it's been a while since it's over. I feel good and I'm starting to get back in the routine of things.
"It took a little while, you take a month off and you go back to Double-A and it's all about timing and rhythm. It's not what I expected. I just pushed forward and pushed through it and just go out there and play."
The former first-rounder played a big role in the Rising Stars Game earlier this month. Franklin was 3-for-4 with a homer and four RBIs, setting AFL records in the process. Since then he's batting .375 (9-for-24) with seven RBIs and three extra-base hits in six games.
"So far, it's going hard day-in and day-out and maintaining focus," Franklin said. "Just going out there with no regrets."
Davis, the Brewers' No. 8 prospect, finished with two hits, two RBIs and two runs scored.
Jed Bradley, Milwaukee's first-round pick in June, earned his first win after allowing two runs on four hits while fanning four over 2 2/3 innings.
Giants prospect Joe Panik was 2-for-3 with a double and an RBI while Jean Segura (Angels) had two hits and scored twice for Scottsdale.
Jeremy Khert (Red Sox) fell to 2-1, surrendering four runs on seven hits over three innings for the Scorpions.
