Contreras went 2-for-4 with a home run, two RBI and a walk in Sunday's 7-4 win over the Reds.
Contreras helped keep the game close with his fourth-inning RBI single and eighth-inning solo homer, both of which trimmed Cincinnati's lead to one. Chicago then rallied for four runs in the ninth for its 103rd win of the year. Contreras played a key role in his team's success this year, slashing .282/.357/.488 with 12 home runs and 35 RBI in 283 plate appearances. The 24-year-old rookie excelled after his call-up in mid-June and should be locked in as the Cubs' starting backstop next year.
