Eoin Morgan knows how infuriating James Taylor can be to play against, so is delighted to have him in his team winning matches for England.
Taylor's maiden international hundred at Old Trafford was the most telling contribution in what captain Morgan described as a "brilliant" all-round performance as England trounced Australia by 93 runs to reduce their Royal London Series arrears to 2-1.
The hosts can therefore still sneak a clean sweep of series victories in all formats this summer against their Ashes rivals, if they prevail again in the final two matches at Headingley on Friday and back in Manchester on Sunday.

Jason Roy (63) and Morgan (62) himself both made important runs in England's 300 for eight, and then spinners Adil Rashid and Moeen Ali shared five for 73 in their 20 overs as Australia never threatened to get close.
Morgan, who put on 119 for the third wicket with Taylor (101), said: "He is great to bat with.
"He's rapid between the wickets - he sort of laps me, which is quite 'enjoyable'.
"He's very unique, the way he plays.
"Having played against him a lot in county cricket, he can be annoying to captain against - which is always a good sign, if he then gets runs for us."
It was a breakthrough contribution after five previous half-centuries for Taylor in 20 one-day internationals.
Morgan senses he is among several players currently making important strides for England in the 50-over format.
"We have seen a lot of players grow up, and that's crucial - because when you come up against a side like Australia, if you're not learning, they can hurt you," the skipper added.
"But I think we are learning.
"I've seen a lot of progression over the last three games - you can always make progression, whether you win or lose.
"We have done that, and it will be a continued test against Australia throughout the rest of the series."
Among the improvers is Roy, who gave England a flying start after Morgan won the toss.
The captain said of the young opener: "He appeared to make it look easy ... effortless, it was great to watch.
"I suppose that is credit to the work he put in before the start of the series."
He was also impressed with both spinners.
"It was very promising. Having options of turning it either way is crucial.
"Adil, as I've said before, is vital to a side when he bowls well - because he can beat the bat on both sides.
"Moeen gives it a real good rip, and doesn't bowl many bad balls."
Australia opener Aaron Finch top-scored with 53 on his comeback from injury, but fell to Rashid - before the next six wickets went for the addition of just 44 runs.
He said: "I put my hand up ... I got off to a good start, got us into a decent position and then threw it away.
"It was an opportunity missed ... and I take full responsibility for that."
