BOSTON (AP) — Jordan Crawford says the young Boston Celtics have a few things to learn about finishing out close games.

Crawford took over the role of teacher Tuesday night, scoring 15 of his 25 points in the fourth quarter to help the Celtics hold off the Milwaukee Bucks 108-100.

“We’ve just got to learn to stay focused and pull out these wins — grind them out,” said Crawford, who was 5 for 5 from the field in the fourth, including three 3-pointers.

Jeff Green added 18 points and Brandon Bass added 16 points and nine rebounds for the Celtics, who were coming off a 92-85 loss to the Bucks on Saturday in Milwaukee.

Of Milwaukee’s three wins this season, two have come against Boston and the Celtics avoided having the total reach three by holding off the Bucks down the stretch.

Avery Bradley scored 15 and Jared Sullinger finished with 12 points as all five starters scored in double figures for Boston, which had lost two of three.

The Bucks had just snapped an 11-game losing streak by beating the Celtics on Saturday in Milwaukee, but couldn’t quite rally from a 13-point deficit in the fourth quarter.

O.J. Mayo scored 19, and Brandon Knight had 15 points and six assists for Milwaukee. Khris Middleton added 14 points for the Bucks, who were outrebounded by the Celtics 40-33.

The Celtics led by as many as 15 points and had a 13-point lead in the final period cut to three twice before holding on for the win.

The Bucks got back in it with a 13-4 run, pulling within 90- 87 on a pair of free throws by John Henson, then made another charge late in the period for a close finish. Knight’s 3-pointer with 1:10 remaining cut Boston’s lead to 99-96, but Sullinger answered at the other end, beating the shot clock with a jumper that put Boston back up 101-96.

Knight missed everything on another 3-point attempt for Milwaukee and the Celtics held on to win it.
