Following his 3-under 68 on Monday at Innisbrook Resort and Golf Club Copperhead Course Barber began the second round ahead by four shots only to see his lead trimmed to a single stroke as he fell to 1-over with a 4-over 76.

However, it could have been a lot worse for the 12th ranked player in the Senior AmateurGolf.com Rankings. While playing the Island Course Barber bogeyed Nos. 2-4 in succession to fall drop back to even-par for the tournament before righting the ship somewhat on the back nine with birdies on the 11th and 16th holes that helped offset a double-bogey on No. 14 and a bogey on No. 17.

So far this season Barber has seven top-10 finishes in senior ranking events but is still in search of his first win of the year. His best 2017 finish so far was a tied for third at the Canadian Senior Amateur.

Fourth-ranked Keith Decker remained at 2-over thanks to a level-par 72 and he will begin Wednesday's final round in second place. Decker was 2-over for the day after a bogey on the 10th but he fought his way back to even-par with 11th and 16th hole birdies.

With a win on Wednesday Decker would capture his third AmateurGolf.com Senior Ranking event victory of the season. Decker has already won the Senior Porter Cup, Dave King Senior Invitational and Society of Seniors Spring Classic this season.

Stephen Maddalena is third at 5-over while Allen Peake and Richard Kerper share fourth at 8-over.

SUPER SENIOR DIVISION

Over on the Copperhead Course Pete Allen turned a two shot deficit into a one shot lead. Allen, 6-over, didn't record a birdie on Tuesday but he was able to play steady enough to move in front.

Neil Spitalny is second at 7-over while Don Russell and George Walker sit in third at 9-over.

GRAND MASTER DIVISION

Jerry Hutton maintained his advantage in the Grand Master Division with a 3-over 74 on the Copperhead Course. Hutton is 3-over and leading by three with 18-holes left to play.

In the second round Hutton birdied twice while bogeying six-times.

On Wednesday he will look to hold off a trio of players who are 6-over in a tie for second; George Washburn, Frank Guise and Mike Nixon.
