The Class A Advanced High Desert infielder homered twice and drove in a season-high six runs as he paced the Mavericks to an 18-9 win over the Lake Elsinore Storm, a victory that also clinched his team the California League South second-half division title.

"I think [that was my best game of the year]. I've been seeing the ball pretty well lately and my teammates were getting on base. I was just able to drive them in and get some good pitches to hit," he said. "We finished the double, clinched the first half and the second half, and we did it in good fashion. The whole team contributed, it was a great team win."

It's been somewhat of a strange year for the 22-year-old. Proscia began his season with the Mavericks and was quickly called up to Double-A Jackson after a hot start that saw him hitting .347 with a .382 on-base percentage and .545 slugging mark in 31 games. He had five homers and 20 RBIs before joining the Generals on May 10.

He slumped in the Southern League, though, hitting .211 in 21 games with four home runs and nine RBIs, and he rejoined High Desert at the beginning of June He said he treated the process as a learning experience.

"Whatever their plans are for me, that's just something I can't control. I keep coming to the ballpark and playing my game. Every day I want to do what I can to help the team win," he noted.

Once again, he flourished with the Mavericks. He hit .343 in June with six homers and 19 RBIs while getting on-base at a .393 clip.

He's saved his best for August and the playoff run, however. In 17 games this month he's hitting. 443 with four homers, 24 RBIs, a .453 OBP and a .771 slugging percentage, figures that have far eclipsed his production from any other month.

Overall, he's hitting. 337, third in the league, with a .944 OPS for High Desert, putting him fifth on the circuit. He also has 22 home runs -- tying him for seventh -- and a fifth-best 90 RBIs.

He said that he thinks the Mavericks as a team produced in an environment where hitting well has simply become the norm.

"Our lineup is built like that. Once a couple guys get hits, everyone else gets hits," he said. "We feed off each other, and [tonight] we threw up a crooked number every inning until the eighth."

On Thursday, No. 18 Mariners prospect Leon Landry went 3-for-5, hitting a two-run homer and scoring five times. Left fielder Mike McGee added a three-run shot in the sixth inning, his 16th of the year.

Brett Shankin (7-2) picked up the division title-clinching win, holding the Storm scoreless over seven innings while scattering six hits and three walks with four strikeouts.
