On a Roller Coaster at AZ ALKMAAR, the Netherlands - Highs and lows come around all the time on the field of play. But man, what a roller coaster it has been over the past few games for me, my teammates and coaches at Alkmaar. In my time here at AZ, we have won several important matches and enjoyed many victories. Yet, it's hard to not rank our huge road win against Ajax Amsterdam in the Dutch Cup semifinal round near the top of the list. We knew our backs were against the wall going into the match, having to play one of our Eredivisie rivals on their home surface for the right to play for the championship in May. However, we kept our faith and believed we could get a big result. We would have been knocking on the door all game long and our defense kept Ajax off the board. Thankfully, we broke through deep into the second half and got a lead, then followed it up with two more goals to seal the win. Having a hand in all three goals was great, but most importantly, we got the win and have the chance to play for a trophy. As I said, they could have been three own goals that helped us advance. What matters most to me is that we won. But with every high, there is usually a low and just a few days later we felt that on the road against RKC Waalwijk. Such a disappointing finish to what started as a phenomenal week as we suffered a tough 2-1 loss against our opponents. Obviously, coming into the match just a few days removed from the Ajax game was tough. But we just didn't come up with the win and three points were direly needed in league play. My teammates and I have to right the ship over the course of our last nine Eredivisie matches, because the last thing anyone wants is for us to be relegated and fall out of the Eredivisie. I know we will pull through and deliver some positive results to finish strong. As you all know, personal accomplishments are secondary in my life as a professional soccer player. I am not playing the game I love every day to chase individual records. However, I do want to thank my fans, followers and members of the news media for their kind words via text, e-mail and social media after Sunday's goal against RKC Waalwijk. Your support through the years has always been appreciated and I hope to continue making you proud in the future representing club and country. In closing, I am looking forward to the possibility of being called up for the United States national team match against Costa Rica. We left Honduras with a tough result, but the hexagonal is an absolute grind in qualifying. It's 10 games, where our team's goals are simple every time out on the pitch. Win the game and get three points. Best wishes and continued happiness to you all. Follow Jozy Altidore on Twitter.
