Slowly but surely, LaMarcus Aldridge is getting more familiar with his new team’s offensive schemes. The veteran forward notched his second double-double of the season to lead the San Antonio Spurs past the Boston Celtics, 95-87 Sunday.

Aldridge had 24 points, 10 rebounds, 5 assists to help the Spurs to their first back-to-back victories of the season after a season-opening loss to rivals Oklahoma City Thunder. In his previous game, the nine-year veteran had 10 points and 11 rebounds in a 102-75 win over the Brooklyn Nets.

The Spurs started off fast leading 23-13 after the first quarter and added a few more by halftime, 44-31. The Celtics never seriously threatened on the way to the blowout loss that dropped them 1-2 for the season.

Kawhi Leonard added 19 points and no other Spurs starters finished in double-figure scoring. However, veterans Boris Diaw and Manu Ginobili ended up with 10 and 13 points, respectively.

The Spurs contained the Celtics to just 35.7 percent field goal shooting (35-of-98 FGs) and 20.7 percent three-point field goal shooting (6-of-29 3FGs).

Boston’s starting backcourt of Avery Bradley and Marcus Smart led the way for the losing side with 18 and 17 points, respectively. Off the bench, Isaiah Thomas added 15 points but needed 18 field goal attempts to get there.

The Spurs end a current three-game road trip against the New York Knicks Monday and Washington Wizards Wednesday while the Celtics try to avoid a three-game skid against the Indiana Pacers in their next game.
