JASON Gillespie is hoping the 'J train' steams in and keeps Yorkshire on track for the LV= County Championship title.
That is one of the nicknames captain Andrew Gale has given to new-ball bowler Jack Brooks, their leading Championship wicket-taker with 52 from 13 matches.
The Yorkshire hierarchy accept that the former Northamptonshire paceman can leak runs and is not as economical as fellow seamers Ryan Sidebottom and Steve Patterson.
But they know that when he strikes, Brooks can often pick up two or three quick wickets to change the course of an innings.
There have been seven examples of this during the summer, the most obvious coming in the second game of the season against his former county at Headingley when he took four first-innings wickets in 22 balls.
He took three in 13 in the first innings against Warwickshire at Headingley and three in 12 in the first innings at Northampton.
Brooks has also taken two wickets in five balls, two in two, two in six and two in seven in matches against Nottinghamshire at Headingley, Warwickshire at Edgbaston, Middlesex at Scarborough and, most recently, Sussex at the same venue.
"Our plan is to bowl quite full and that hasn't changed in the whole time that I've been at the club," said coach Gillespie.
"Sometimes you don't get it right – somebody like Jack Brooks, who can go for runs.
"But Galey always talks about how you never know when the J train comes in and goes bang, bang, bang.
"Sometimes he can go for runs but we know what he's trying to do and we're fully supportive of that.
"When we get it right, it works, and Steve Patterson probably gets it right as consistently as anybody.
"The stats show that him and Siddy get the ball on a fuller length more than anybody else in the country."
Brooks, Sussex's Steve Magoffin (53) and Lancashire's Tom Smith (53) are the three top wicket-takers in Division One.
After coming up against Magoffin last week, Brooks and Smith now meet in the Roses clash at Emirates Old Trafford on Sunday.
