With B-Meg Llamados' (Purefood's Tender Juicy Giant's new name) frontline depleted because of injuries to Marc Pingris, Kerby Raymundo, and Rafi Reavis, Maierhofer got a lot of playing time in 2010–11 PBA Philippine Cup, and he responded by averaging, for the tournament, 9.6 rebounds (5th in the league) and 1.2 blocks (4th) — leading the team in both categories.

[2] Since joining Ginebra, he admittedly struggled to get playing time in a roster filled with big men like Kerby Raymundo, veterans Rudy Hatfield and Willy Wilson, and now the 6-foot-9 Japeth Aguilar.

[4] While playing for Energy Cola, he was a part of the formidable veteran crew which gave Petron Blaze Boosters a run for their own money during their 2013–14 PBA Philippine Cup best-of-3 quarterfinal matchup, yet they were swept in that series.

The series of trades started with San Miguel, formerly Petron, acquiring Maierhofer from Barako Bull in exchange for Jason Deutchman and the Beermen's second-round picks in 2016 and 2017.

In the third step, Barako Bull acquired veteran wingman Leo Najorda from GlobalPort in exchange for guard Jonas Villanueva, who was traded by the Batang Pier to Air21 for Bonbon Custodio.
