Colin Montgomerie (l) with Bernhard Langer during the opening round of the Senior Players Championship in Pittsburgh
John Huston is the early pacesetter after the opening round of the Senior Players Championship in Pittsburgh where former European No 1 Colin Montgomerie made his American debut on the Champions Tour.
Monty, who turned 50 last week, made a solid start to his senior career in the States with a 69, which left him four strokes behind Huston.
The 52-year-old from Florida carded an opening five-under-par 65 at Fox Chapel to end the day one shot clear of four players.
On a day dominated by Americans, home players fill the top-10 spots - and 18 of the leading 20.
Huston, who teed-off on the 10th, made a slow start to his round before covering an eight-hole spell in six-under, while playing his second nine holes in just 30 shots.
Fred Couples, Duffy Waldorf, Fred Funk and Russ Cochran are tied-for-second and leader Huston said: "I really didn't make anything and then all of a sudden the last 10 holes I made a bunch of putts."
As for Monty, he overcame a double-bogey six at the eighth to end the round tied-for-21st, along with Englishman Roger Chapman - and is well in contention.
Montgomerie admitted earlier in the week that this tournament has been on his radar for a long time: "I've got a new hunger for the game now and I've been working all year towards this date."
