The veteran former Walsall star continued his outstanding batting record at Glasshouse Park with a superb 101 before grabbing three for 37 from tidy overs of medium pace as Wardens subsided to 136 all out in response to the visitors’ 261 for six.
This result leaves both clubs locked alongside Wolverhampton and 2014 champions West Bromwich Dartmouth with a single victory after five matches as the Birmingham League reverts to its traditional 55-over win/lose/draw format for the next 11 weeks.
Boroughs arrived in the middle after some wayward home bowling had allowed openers Danny Irvine and Adam Hewlett to add a breezy 40.
He proceeded to dominate a second-wicket stand of 84 with Irvine (36) before Joe Crichard (21) joined him in a useful 50-run third-wicket alliance.
Wardens scented opportunity when Brock’s skipper was finally dismissed, having struck seven boundaries and four maximums in his superb 116-ball knock.
However, a late flurry from sixth-wicket duo Nick Powell (35) and Jack Aldous-Fountain (16 not out) then took the visitors beyond 250.
Slow left-armers Sitanshu Kotak (3-43) and Matt Hancock (0-35) were the pick of the home attack.
After tea, Nick Seager (20) and Scott Stenning (26) got starts in the hosts’ top order, but Boroughs removed both, plus Keith Bell, to reduce the chase to 64 for three.
Worse followed for Martin Donald’s side as the middle-order folded to Powell (3-16) and, when Kotak (26) fell to Matt Veale, Hewlett (3-23) was left to mop up the tail and condemn Wardens to heavy defeat.
A superb five-wicket haul from young seamer Luke Green was unable to prevent Kenilworth Wardens’ 5th XI slipping to an 89-run friendly defeat at the hands of Alvechurch 3rds.
Green’s three early strikes had the hosts under pressure at 55 for five and he returned to complete a first ‘Michelle’ in adult cricket by mopping up the tail.
However, between Green’s two spells, the hosts’ middle-order duo Bilal Malik (66) and Jordan Rollins (55 not out) dominated the middle section of the innings.
Along with a useful contribution from opener Josh Williams (32) and 47 extras, this ensured the hosts posted a competitive-looking 228 for eight from their 45-over allocation.
Opener Les Reid (17) and skipper Joe Mills (21) got Wardens’ chase away to a good start before three wickets from Steve Lines and Saeed’s two for nine pegged back the middle-order.
Some useful late blows from Chris Porter (19 not out), Gareth Evans (15) and Fintan Hanley (16) saw the visitors close on 139 for eight.
