A season-best performance from reserve Trevor Thompson couldn’t breathe life into the Santa Cruz Warriors’ dwindling chance of making the postseason.

Thompson, a 7-foot center out of Ohio State, had a season-best 21 points and five rebounds in 13 minutes, but the Warriors lost the G League game to host Sioux Falls 119-105 in front of 2,312 fans at Sanford Pentagon on Tuesday night.

The Warriors, who trailed by as many as 20 points, never led.

Santa Cruz (21-22) falls to 3.5 games behind Texas (24-18) for the sixth and final playoff berth in the Western Conference. The Warriors have six games remaining in the regular season, including Saturday’s contest at Memphis (17-27).

Two-way forward Chris Boucher had 21 points and 15 rebounds, but Santa Cruz was unable to match Sioux Falls’ depth. Boucher, a former standout at Oregon, has three double-doubles this season, all coming in the past five games.

Starting forward Damion Lee scored 18 points and Avry Holmes added 12 in 26 minutes off the bench.

Damian Jones, a 7-foot center on assignment from Golden State, and CJ Wilcox, a two-way guard for Portland, which does not have a G League affiliate, each chipped in 11 points for Santa Cruz. Jones had five of Santa Cruz’s 17 turnovers.

Jeremy Pargo, a 31-year-old guard claimed off waivers last month, scored eight points, the first time he has been held under 10. But he recorded 13 assists — his third straight game with more than 10. He has 52 assists through five games.

Sioux Falls, which sits atop the Western Conference’s Midwest Division, shot 50 percent from the field (40 of 80) with 10 3-pointers. It made more free throws (29) than the Warriors attempted (16).

Two-way forward Derrick Jones Jr. led the Skyforce with 24 points, four rebounds, three assists and three blocked shots. Forward Torrey Craig put up a near-identical outing, scoring 20 points with three rebounds, four assists and a team-high four blocks.

The Skyforce finished with 10 blocks.

Center Kadeem Jack posted a double-double with 13 points and 12 rebounds. Starting guard Ike Nwamu had 17 points with five 3-pointers.

Two other Skyforce players who played for Team USA during FIBA Americas World Cup Qualifying in Santa Cruz last month reached double digits in scoring in reserve roles: Guard Larry Drew II had 16 points and forward Alonzo Gee added 13.
