With the NHL pausing the 2019-20 regular season March 12 due to concerns about the coronavirus, here's a look at the top six NHL rookies age 25 and older (NOTE: A player at least 26 years of age, by Sept. 15 of that season, is not considered a rookie):

The play of several high-profile rookies, including forwards Jack Hughes of the New Jersey Devils and Kaapo Kakko of the New York Rangers, the No. 1 and No. 2 picks of the 2019 NHL Draft, respectively, is one of the major storylines of the 2019-20 season. Each Monday, NHL.com will examine topics related to this season's class in the Rookie Watch.

1. Elvis Merzlikins (26 years, 7 days), G, Columbus Blue Jackets: A third-round pick (No. 76) in the 2014 NHL Draft, Merzlikins is tied for second in the League among goalies with five shutouts (Marc-Andre Fleury, Vegas Golden Knights; Tuukka Rask, Boston Bruins) and is a big reason the Blue Jackets are tied with the Carolina Hurricanes for the first wild card into the Stanley Cup Playoffs from the Eastern Conference. Merzlikins is 13-9-8 with a 2.35 goals-against average and .923 save percentage in 33 games (31 starts) and has a .900 save percentage or better in 61.3 percent of his starts. He ranks first among rookie goalies (at least 15 games played) with a .926 save percentage at even strength despite getting the least goal support (2.35 goals-for average) of any first-year goalie with at least that many games played.

Ilya Mikheyev (25 years, 193 days), F, Toronto Maple Leafs: He was having a productive first season in North America before needing surgery on an artery and tendons in his right wrist Dec. 28 and had returned to practice prior to the pause in the NHL season. Mikheyev (6-3, 195), signed by the Maple Leafs as a free agent May 6, 2019, is third among rookies in the Atlantic Division with 23 points (eight goals, 15 assists) and 98 shots on goal in 39 games.

Roy leads all NHL rookies with 132 hits and is second with 100 blocked shots.

6. Marcus Hogberg (25 years, 147 days), G, Ottawa Senators: The third-round pick (No. 78) in the 2013 NHL Draft is one of 11 rookies the Senators have used this season. The Sweden-born goalie (6-5, 209) is 5-8-8 with a 3.12 GAA and .904 save percentage in 24 games (21 starts) for Ottawa, which has averaged 3.35 goals-against this season and 33.6 shots-against per game.
