MIAMI -- Here are 10 facts and figures to keep in mind for Sunday's Celtics-Heat Game 4 clash (ABC, 1 p.m) at the AmericanAirlines Arena (information researched for ESPN by Elias Sports Bureau, Inc.):

1. As we noted in today's column, the Celtics have not swept a best-of-seven series since winning the first four games of the 1986 Eastern Conference Finals against the Bucks. The Celtics have completed 20 best-of-seven series since the last time they swept one. Only two teams have a longer current streak of consecutive best-of-seven series played without registering a sweep than Boston: the Hawks (32 straight) and Wizards (26 straight).

2. Doc Rivers is only 5-10 in games in which his team has had a chance to clinch a playoff series in his career as a head coach. Only one head coach in NBA history has a lower winning percentage than Rivers in those games (minimum: 15 games): Fred Schaus (5-13, .278).

3. Paul Pierce has scored 40-or-more points in a game in which his team has had a chance to clinch a playoff series twice in his career (46 points in 2002 first round and 41 points in 2008 conference semifinals). Only two players that were active in 2009-10 have as many 40-point games in potential series-clinching games as Pierce: Allen Iverson (three) and Kobe Bryant (two).

4. Dwyane Wade has scored 25-or-more points in each of his last six postseason games dating back to the 2009 playoffs. That is the longest current streak for any player in the league.

5. Jermaine O'Neal is shooting only 16.1 percent from the field in this series (5 for 31). Over the last 40 years, only two players have made less than 20 percent of their field-goal attempts in a postseason series (minimum: 30 attempts): the Lakers' Willie McCarter in the 1971 conference finals (6-for-31, .194) and Washington's DeShawn Stevenson in the 2007 opening round (9-for-46, .191).

6. O'Neal's teams have posted a 33-46 (.418) record in the 79 postseason games he has appeared in. Only two active players have a lower career personal winning percentage in the postseason than O'Neal (minimum: 50 games): Eduardo Najera (19-37, .339) and Marcus Camby (28-40, .412).

7. Michael Beasley is shooting 35.3 percent from the field in the first half and 62.5 percent from the field in the second half in this series. That 27.2 percentage point increase in field-goal percentage from the first half to the second half is the largest for any player in the 2010 playoffs (minimum: 15 FGA in each half). Rajon Rondo has the second largest decrease in field-goal percentage from the first to the second half in this postseason (.600 to .222; -.378) behind Paul Millsap ( -.461).

8. The Celtics have outscored the Heat by 53 points in the 72 minutes that Glen Davis has been on the court in this series. That is the largest plus-minus differential for any player in the 2010 postseason. In the 72 minutes that Davis has not played, Boston has been outscored by 13 points.

9. Boston has won the first three games of this series after winning all three games against Miami during the regular season. Since the current playoff format was instituted in 1983-84, there have been six instances in which a team swept a best-of-seven series from a team after sweeping the season series of three-or-more games: Boston vs. Milwaukee in 1986 (5-0 in regular season), Seattle vs. Houston in 1996 (4-0), Miami vs. New Jersey in 2005 (3-0), Miami vs. Washington in 2005 (4-0), Detroit vs. Orlando in 2007 (4-0) and the Lakers vs. Denver in 2008 (3-0).

10. Wade is averaging 25.9 points, 5.9 assists, and 5.3 rebounds per game in 64 career playoff games played. Only four other players in NBA history are averaging at least 25 points, 5 rebounds and 5 assists per game in the postseason (minimum: 40 games): Allen Iverson, LeBron James, Michael Jordan and Jerry West.
