Alker also wore ribbons with the Astros logo on his cap this week in honour of Workman.
Alker, who had his son Ben caddying for him for the first time this week, said it was an emotional victory.
“You can see the emotion on 18. I just saw a sea of orange today. It just reminded me of Sam,” Alker said.
“I had my son on the bag and it doesn’t get any better than that.”
Stricker was five shots behind going into the final round. He was slowed by a double bogey on the third hole, but wound up with nine birdies in his round of 65. The runner-up finish enabled Stricker to take the lead in the Charles Schwab Cup over David Toms, who tied for third with Colin Montgomerie.
Alker, who finished at 15-under 201, won for the first time this year. He won the Charles Schwab Cup last year and was voted player of the year.
”I hit it great off the tee and hit some nice iron shots, and I got it done on the back,” Alker said. “I haven’t defended a championship. I had a whole bunch of reasons today to try and win this golf tournament, and it worked out.”
Stricker knew he needed a big closing round to have a chance and his tee shot into the water on the par three third hole was going to cost him. But he played with Alker on Saturday and could see him playing well. Stricker also noticed plenty of orange Astros gear in honour of Alker’s late caddie.
”It’s meant to be for him here, really,” Stricker said. “His caddie passing a few months ago, big Houston guy. I saw some Houston Astros jerseys walking around the course today, saw some at breakfast this morning. It’s good that he’s going to win here.”
