The 30 year-old goalkeeper registered his 13th clean sheet of the season. In total, he has now kept 54 in 126 games for the Blues so far.
Walton currently sits joint seventh in the standings alongside Mick Burns, who also kept 54 clean sheets in 171 games for the Blues between 1938 and 1952.
Let’s take a look at the top six…

6th: LAURIE SIVELL
The Lowestoft-born diminutive keeper came through the youth ranks at Town, making 175 appearances between 1970 and 1984.
Sivell kept 58 clean sheets for the Blues and was largely an understudy to David Best and then Paul Cooper during his time at the club.
He was a vital part of Ipswich’s squad which won the FA Cup and UEFA Cup, but suffered some horrible injuries, most famously when diving at the feet of Aston Villa’s Andy Gray.

5th: DAVID BEST
The shot stopper played for the Blues between 1968 and 1974, keeping 62 clean-sheets in 196 games during his spell at Portman Road.
Best was a key part of Sir Bobby Robson’s first European campaign with the Blues, keeping a clean sheet in both legs of the famous 1-0 aggregate UEFA Cup victory over Spanish giants Real Madrid in 1973/74.
He was also in goal for both legs of the 1972/73 Texaco Cup victory over Norwich City, the first trophy Robson won as a manager.

4th: ROY BAILEY
The South African goalkeeper made 348 appearances for the Blues, keeping 69 clean sheets in the process.
Bailey was signed by Sir Alf Ramsey from Crystal Palace in March 1956, spending nearly a decade in Suffolk.
He was in goal as Town won the Third Division South title in 1956/57, before being pivotal to lifting the Second Division title in 1960/61 and then the First Division the following season.

3rd: CRAIG FORREST
The big Canadian spent over a decade at Portman Road, keeping 73 clean sheets in 312 games during his spell with the Blues.
Forrest, who was a commanding presence, played every game for Town as they claimed the Second Division title in 1991/92 to win promotion to the newly-formed Premier League.
He is, unfortunately, probably best known as the keeper who conceded nine goals against Man Utd in 1995 – still a Premier League record.

2nd: RICHARD WRIGHT
The Ipswich-born goalkeeper came through the ranks at Town, where he made 355 appearances during his three separate spells at Portman Road.
Wright kept 119 clean sheets for the Blues, winning his first on his senior debut in a 2-0 home win over Coventry City in the Premier League in May 1995.
He helped Town win promotion back to the top flight in 2000, before playing a vital part in the side who finished fifth in the 2000/01 campaign.

1st: PAUL COOPER
A stalwart of Robson’s great teams of the 1970s and early 1980s, lifting the FA Cup and UEFA Cup.
Cooper kept an impressive 186 clean sheets in 575 games for Town, having signed initially on a month’s loan from Birmingham City in 1974, before joining permanently that summer.
He wasn’t the tallest, but he was supremely agile and, of course, built a reputation as a fantastic saver of penalties – including eight in the 1979/80 season.
