The story of Sunderland's spot-kick success
Jermain Defoe's two penalties for Sunderland against Liverpool on Monday extended one of the Premier League's more remarkable records into a sixth year.
Defoe netted in each half at the Stadium of Light - the 22nd and 23rd successive spot-kicks the Black Cats have converted in the Premier League.
They have a perfect record from the spot since 2012, with their last miss coming in December 2011 when Sebastian Larsson saw his effort against Wolves saved by Wayne Hennessey.
Nicklas Bendtner scored against derby rivals Newcastle with Sunderland's only penalty in a league game in 2012 and they then went a perfect six from six the following year - Craig Gardner with five of those before Ki Sung-yueng scored against Everton.
Fabio Borini had three of Sunderland's five in 2014 and, after they scored another three the following year, Borini extended the sequence to 17 in last April's 3-0 win over Norwich.
Defoe has then taken centre stage, converting four before 2016 was out and adding two in the first game of the new year.
The six strikes leave him one ahead of Gardner in Sunderland's tally, with Borini adding four.
Adam Johnson and Jordi Gomez contributed three apiece, Gomez scoring two penalties in one game to beat Southampton in May 2015, with one each for Bendtner and Ki.
Of the 21 games involved, Sunderland have won 10 and lost only four, with Monday's fixture their seventh draw.
Newcastle have been on the receiving end three times, Borini and Johnson each scoring in 3-0 Sunderland wins following the 1-1 draw in which Bendtner set the run in motion.
Three more have come against Southampton - Gomez's brace and one for Defoe this season, with two each against Fulham, Norwich and Arsenal as well as Liverpool.
Liverpool have themselves scored their last seven league penalties, but Sunderland's nearest challengers are Swansea, with 14 in a row since Manchester City's Joe Hart saved from Scott Sinclair in the Swans' maiden top-flight season in 2011-12.
