SBLive-HIU SoCal Senior All-Star Game home team roster: Meet the players & coaches

The home team will be coached by Bianca Ziemann (Crean Lutheran), Kerwin Walters (Sage Hill), and Matt Tumambing (Ontario Christian).

Last week we officially announced the first ever SBLive SoCal Senior All-Star Game, Hosted by Hope International University, set for 6 p.m. at HIU on Saturday, May 7.

While team names are still yet to be determined, it's time to unveil the finalized rosters for the event, starting with the home team.

The home team is loaded with three of the top coaches in Southern California, a slew of D-1 commits, and several other star seniors who're both committed and uncommitted for college ball. All stats and awards referenced pertain to the 2021-22 season unless noted otherwise. Coaches and players are listed in alphabetical order.


Matt Tumambing – Ontario Christian

Before Mumambing took over three years ago, Ontario Christian had long struggled to stay afloat, and had some seasons of winning five or fewer games in the not-too-distant memory. In only three years with the Knights, Tumambing already totes an astounding overall record of 85-12 for a program that continues going on deep playoff runs even as it rises up the divisions. That's 69-6 in the regular season and 16-6 in the playoffs, including a half dozen of CIF finals or semifinals appearances. 

Kerwin Walters – Sage Hill

Since taking the reins of a struggling program in 2012-13, Walters has built Sage Hill into the one of the fastest-rising contenders in the Southern Section. The Lightning went 13-32 in his first two seasons there before turning into a winner, and then, a 2020-21 CIFSS 3-AA champion and 2021-22 Division II State champion. He now has a record of 128-63 in his last seven seasons and a cumulative record of 153-109 with the Lightning, which also made the Southern Section 2-AA finals this past season.

Bianca Ziemann – Crean Lutheran

Ziemann was named the Saints' interim head coach in the 2019-20 season, and went on to guide them to a 28-6 campaign and CIFSS 3-AA finals appearance. After the season, she shed the interim tag and was officially named co-head coach – alongside twin sister Rachael Ziemann – in addition to director of girls basketball and strength & conditioning coach. Her cumulative record in three seasons at Crean Lutheran is a gaudy 65-16, including 9-5 in the playoffs and 26-4 in league play with a 2022 Empire League title. The playoff record also includes appearances in the quarterfinals and semifinals, respectively, in the last two postseasons of Southern Section 2-AA playoff action.

Hannah Stines

-4-star Washington commit and one of the most offensively gifted players in the state. Point guard with the size of a forward who played literally every position in high school, including matching up with centers. Makes both passes and deep threes off the dribble routinely that almost no other players make even occasionally. Sees plays developing many steps in advance and delivers with smooth execution. Had a sensational junior campaign in which she led OA an CIFSS Open Division playoff birth averaging 19.4 points, 8.8 rebounds, 5.4 assists, 4.2 steals, and 1.5 blocks per game hitting over two threes per game at a 41% clip.

-Bruising double-double machine who pairs a great sense of positioning and spacial awareness in the post with impressive touch with either hand around the basket.

Averaged a team-high 14.4 PPG and also led CdM in rebounding. Earned an All-Orange County nod from OC Register and SBLive.

SG/SF Sophia Williams – Brea Olinda – 5-10
