Made the saves he had to and dealt with the aerial threat posed by the Hammers by dealing with any set-pieces with catches or punches.
Skippered the side and was a rock at the centre of defence with a number of towering headers and crunching challenges. Nearly grabbed his second goal in as many home games with a firm downward header which hit the bar.
Another colossal presence at the back, he dominated Maiga at times and made sure James Chester was not missed as much as Tigers fans thought he would be.
Looked nervous in the opening exchanges, summed up in particular by a wayward backpass but grew into the game and, as his confidence grew, his willingness to get forward became more apparent.
Came back into the Tigers' backline and settled back into his position like a duck to water. Made some crucial interventions and blocks to stifle the Hammers.
Confused the Hammers' rearguard by dropping short and picking up possession whilst also showing the intent to dart in behind into the channels to help hold the ball up for his side. Following his goal last week, another positive display.
Ahmed El Mohamady
An impressive display from the versatile right midfielder who looked to get at his full-back as often as possible and whip a ball into the area. Equally, he was always looking to help out Rosenior at full back.
Sat at the base of the Hull midfield which, in turn, helped liberate the creative talents in front of him. Was largely on the periphery on the game at times, though, although it was slightly understandable given his role. So nearly grabbed a second, that said, with a low drive that hit the post.
Sprayed the ball around with consummate ease at times but his final delivery was sometimes surprisingly off. Was reliable enough from a defensive perspective when called upon.
Another laboured performance from the Tigers' most disappointing individual on the day. His touch was off and link-up play with those behind him therefore suffered. Snatched at a presentable second-half opening. Rightly hauled off.
Dispatched the penalty superbly and his all-round performance was an exciting one. The KC faithful chanted his name at every given opportunity and it reflected in some of the flair and confident wing-play he displayed on the left flank. Was taken off to a rapturous applause.
Had no chance of saving the penalty and made some impressive stops when Hull threatened his goal. Was often let down by those in front of him.
Not as assured as he has been in recent times, which may well have been down to a change in defensive partner. Aluko gave him a real test down the middle and when he shifted out wide.
Got forward with intent and put in some teasing crosses but his delivery was not always in the right place for a Hammers forward. Defensively suspect but let down by Jarvis' lack of backtracking.
Hull deliberately targeted his flank as one they could get at and, subsequently, any attacking inclinations were reserved for defensive responsibilities. Harshly penalised for the opening goal.
Saw a header cleared off the line but not his best performance at the back as he came in for Collins. Constantly looked under pressure when on the ball and didn't deal with Aluko.
Poor display. Gave the ball away frequently, offered no defensive protection and failed to beat his marker often enough, let alone supply the crosses for which he is renowned.
Given his early season form, he will be disappointed by this display but his effort could not be questioned as he constantly asked questions of the Tigers in midfield and at the back.
Was trusted with the defensive-minded right-wing role and helped force Figueroa back but lacked the inventiveness needed in the final third.
Sent off last week and unable to provide enough guile or bite in midfield to offer and sort of problem to the defensive midfield duo of Livermore and Huddlestone.
Booked for an early reckless lunge and his game never recovered from it. Didn't offer enough in the hole behind Maiga and seemed more willing to back chat to the referee than pull his team through the battle.
Cut an isolated figure up front as he battled resolutely against the physical presence of Faye. Had a low shot saved in the opening period but offered little else due to a criminal lack of service. Withdrawn as the Hammers went in search of the elusive goal.
Made very little impact during his 10 minutes on the field.
Was forced to rely on scraps as his side defended for their lives to hang on to the lead. Could not get into the game.
Came on for the final exchanges and offered no real contribution to the Tigers' success.
Supplied some impressive crosses and was always forward-thinking after he was brought on.
Was introduced midway through the second half and at least showed the makings of a more orthodox centre forward as he held the ball up and invited midfielders into attacking positions.
Ricardo Vaz Té
Did not offer enough support to Petric when he was introduced and was forced wide to try and get hold of the ball.
