Hagel opened the scoring with a short-handed goal at 3:49 of the opening period when he raced down the right side and opened up for the one-timer to finish off a 2-on-1 break.
A flurry of goals would follow, with Hagel cashing his second of the game high glove side off a nice back door feed at 15:14 of the middle frame to make it a 5-4 Rebels lead.
The teams posted seven goals each in regulation, and Hagel took advantage of the extra time by streaking down the left wing boards and releasing another quick snipe over the goaltender's glove at 3:03 to capture the milestone marker and seal the victory.
Hagel began the week with a helper in a 5-2 loss at Brandon on Friday, and closed it out with a power-play goal plus an assist in Sunday's 8-4 loss at Regina to extend his career-best point streak to six games.
The productive week ups Hagel's season totals to eight goals and 20 points through 19 games.
Cliff Pu (2016, third round) assisted on London's final goal in a 7-0 rout of Kingston on Friday, and then followed up with a two-goal effort Saturday in the Knights' 4-1 win over Guelph.
Pu is currently riding a 14-game point streak, tying Sam Reinhart (2014-15) and Giorgio Estephan (2015-16) for the longest point streak for a Sabres prospect in recent years. He has 12 goals and 30 points in his first 16 games.
Austin Osmanski (2016, seventh round) finished with a minus-2 rating last week as Mississauga suffered a pair of 5-4 losses to Oshawa and Ottawa. The second-year defender has four points (1+3) and a minus-7 rating in 17 games.
Giorgio Estephan (2015, sixth round) produced four shots on goal for Team WHL as they split a pair of games with the Russian Selects at the CIBC Canada Russia Series.

Kelowna defenseman Devante Stephens (2015, fifth round) logged an even rating Saturday as the Rockets cruised past Prince Albert 7-1. Stephens has been solid in a middle-pair role this season, posting four goals and seven points through his first quarter of the season.
Fresh off a two-game performance with Team WHL in the CIBC Canada Russia Series that saw him post two total shots on goal, Prince Albert defenseman Brendan Guhle (2015, second round) submitted a highlight-reel play Friday, skating the puck end to end through all four penalty killers and shooting the gap between the final two defenders for a backhand finish as the Raiders dropped a 5-2 decision in Kamloops.
Guhle, who picked up an assist Saturday to extend his point streak to three games in a 7-1 loss at Kelowna, has collected four points (2+2) in his first dozen games.
Vojtech Budik (2016, fifth round) logged a cumulative minus-5 rating as Prince Albert fell to Kamloops and Kelowna. The Czech defender has five assists in 17 tilts for the struggling Raiders squad.

Brown forward Maxwell Willman (2014, fifth round) scored a power-play marker in Friday's 4-2 loss to Cornell, and added another goal with the man advantage, the game-winner, in Saturday's 4-2 victory over Colgate. Willman has goals in three consecutive games for his only points of the season through six outings.
Christopher Brown (2014, sixth round) batted a rebound over the goal line for his first collegiate power play goal Tuesday as Boston College skated to a 5-3 win over New Hampshire. Brown went on to produce three shots on goal in Sunday's 3-1 victory over visiting Arizona State. The sophomore forward has 12 points (4+8) in 13 games. He had two goals and 11 points in 41 games last season as a freshman.
Boston College defenseman Casey Fitzgerald (2016, third round) quickly drilled a shot short-side from the left point off a faceoff draw in Tuesday's victory over New Hampshire. On Sunday, the sophomore was kept off the scoresheet in the win over Arizona State.
Fitzgerald scored four goals as a freshman in 39 games, but has already equaled that number in 12 games this season en route to capturing 11 total points.
Notre Dame goaltender Cal Petersen (2013, fifth round) made his 59th-consecutive start Friday, allowing two goals on 25 shots to backstop the Fighting Irish to a 5-2 victory at Northeastern.
In Sunday's rematch, Petersen stopped all 16 shots sent his way before the scoreless game was suspended after 40 minutes due to a Zamboni breaking down and damaging the playing surface. It has yet to be determined if the final period will be played at a later date. Peterson has gone 5-3-1 this season with a 2.41 goals-against average and a .913 save percentage.
Sophomore forward Connor Hurley (2013, second round) was limited to one shot on goal Friday as Notre Dame got past Northeastern, and recorded another shot on goal before Sunday's game was called due to poor ice conditions. Through nine completed games, Hurley has scored twice and added eight helpers.
After netting one assist Friday in Harvard's 5-2 victory at Princeton, senior forward Sean Malone (2013, sixth round) scored his third goal of the season Saturday off a second-chance whack at the puck as the Crimson suffered their first defeat of the season, 4-2 at Quinnipiac. Malone has seven points (3+4) through his first six games.
Ivan Chukarov (2015, seventh round) totaled five shots on goal as Massachusetts defeated Merrimack 3-1 on Friday before dropping a 2-1 decision to Vermont the next night. Through nine games, the sophomore defender has two assists and a team-best 22 shots on goal.
St. Cloud State forward Judd Peterson (2012, seventh round) connected for his second three-point game of the season Friday, posting his team-leading seventh goal and adding a pair of helpers as the Huskies routed Colorado College 7-3. Peterson submitted two shots on goal the following night as the Huskies earned the road sweep with a 4-1 win, giving the junior centerman 10 points in as many games.
William Borgen (2015, fourth round) logged one assist and a plus-3 rating in St. Cloud State's sweep at Colorado College. Borgen has points in four of his last five games to elevate him to seven (0+7) at the 10-game mark.

Brett Murray (2016, fourth round) went without a point this past week as Youngstown dropped a pair of home-ice decisions to Bloomington by scores of 3-1 and 4-1. Murray has gone quiet in his last three games, leaving him with four goals and 14 points in his first 16 tilts.
University of Wisconsin commit Philip Nyberg (2016, fifth round) posted a team-high five shots on goal Friday as Madison doubled Team USA 4-2. Nyberg came up empty in Saturday's rematch as the Capitols fell 4-1, but garnered one assist on Sunday in a 5-4 overtime loss at Muskegon. Nyberg has four points (1+3) and a minus-8 rating in 14 contests.
Rasmus Asplund (2016, second round) failed to connect in Thursday's 2-1 shootout win over Linkoping HC, and went without a point for the third-straight game in a 1-0 overtime victory over IF Malmo Redhawks on Saturday. In 14 games, Asplund has collected three goals and seven points.
Victor Olofsson (2014, seventh round) curled off the wall and saw his shot from the right faceoff circle deflect off a defender into the net for his third goal of the year Saturday as Frolunda HC blanked Karlskrona HK 3-0. Olofsson, who picked up an assist in Thursday's 4-3 loss to Djurgarden IF, has points in three straight games and four of his last five to boost his season total to seven (3+4) in 17 contests.
Jonas Johansson (2014, third round) made 19 saves Wednesday in his only start of the week as Almtuna IS was doubled by VIK Vasteras HK 4-2. Johansson has battled a to 6-7 record this season with a 1.70 GAA and a .935 save percentage.
Djurgarden IF winger Gustav Possler (2013, fifth round) remains sidelined with a lower body injury. He has yet to play a game this season.
