2011-12: Baertschi made his NHL debut with the Flames in March after a dominant junior season with the Portland Winterhawks. He scored 3 goals and was plus-two with 4 penalty minutes in five games with Calgary. Baertschi and St. Louis prospect Ty Rattie were one of the most prolific scoring duos in junior hockey. Baertschi was the second-leading scorer for Portland behind Rattie and finished tenth in the WHL with 94 points (33 goals, 61 assists) despite skating in just 47 games due to an early season hip injury. Portland reached the WHL Finals after finishing second in the U.S. Division during the season. Baertschi was plus-11 with 14 goals and 20 assists in 22 playoff games.
Baerstchi is a good two-way player with high-end offensive talent. The playmaking winger has really improved his skating explosiveness while learning to change speed to throw off the defender. Since being drafted in 2011, he has really improved his vision and hockey sense as well as his overall game. The first rounder clearly projects as a top line forward. His work ethic, passion, desire and attitude to be the best are top notch.
With an extended lockout, Baertschi will have the chance to stay in the AHL and showcase his offensive talents to start his professional career. The 20-year-old will mostly likely make the jump into the Flames' starting line-up and injuries could be the only thing that stops Baertschi from being a star player with the Calgary Flames in the next few years.
