Career best, and worst
Starting with the 2014-15 season, the Red Wings began seeing more of Petr in the net as both the Wings’ starting and backup goaltenders were plagued with injuries during the season. He would continue to show his talent during this time period, going 16-9-2 with 26 starts in 29 games. With a goals-against average of 2.38 and a .918 SV%, Petr was on track to go full-time in Detroit’s net.
The 2015-16 season saw Petr on the full-time roster for Detroit, along with Jimmy Howard. Petr would take on the starting role for this season, playing in 54 games with 49 starts. Of those 49 starts, Hockey-Reference.com lists him with 31 quality starts (a .633%). It would be his last good career year in Detroit, with a 2.33 GAA and .921 SV%.
The 2016-17 season is when things began to unravel for Mrazek. He was still Detroit’s starting goaltender, appearing in 50 games in the season, and starting 44 of them. Of those games, Petr only registered 18 wins, a single shutout, a 3.04 GAA, and a .901 SV%. 19 of those 44 starts are listed as quality starts, showing a very sudden slide in performance from the previous season.
With his sudden downturn, Petr is relegated to the backup role, with Jimmy Howard taking over the starting role for 2017-18. He suits up for 22 games, starting 18 of them, and goes 8-7-3 with 3 shutouts. A 2.89 GAA and .910 SV%, with 7 quality starts shows he’s on the uptick again. However, Detroit trades Mrazek to Philadelphia in February in return for two conditional draft picks.
